Uninterruptible power supply for it is needed. How the uninterruptible power supplies (UPS) are arranged and operated. Often emerging problems

As a development, civilization begins to consume more and more energy, in particular, electric - machines, plants, electric pumps, lights on the streets, lamps in apartments ... The appearance of radio, televisions, telephones, computers gave humanity the opportunity to speed up the exchange of information, however, tied even more Its to sources of electricity, since now, in many cases, the disposal of electricity is equivalent to the loss of the delivery channel information flow. This situation is most critical for a number of the most modern industries, in particular, where computer networks are the main tool.

It has long been calculated that through a couple of months of operation, the cost of information stored on the computer exceeds the cost of the PC itself. For a long time, the information has long been a type of product - it is created, assessed, sell, buy, accumulate, transformed ... and sometimes lose in a wide variety of reasons. Of course, up to half of the problems associated with the loss of information arise due to software or hardware failures. In all other cases, as a rule, problems are associated with poor-quality power supply of the computer.

Providing quality nutrition of PC components - pledge stable work Any computer system. From the form and qualitative characteristics of the network nutrition, the fate of the whole months of operation depends on the successful choice of nutritional components. Based on these considerations, the following methodology was developed below, designed to further become the basis for testing the qualitative characteristics of uninterrupted power supplies.

Positions GOST

All that is associated with electrical networks, in Russia is regulated by the provisions of GOST 13109-97 (adopted by the Interstate Council for Standardization, Metrology and Certification, in return for GOST 13109-87). The standards of this document fully comply with international standards IEC 861, IEC 1000-3-2, IEC 1000-3-3, IEC 1000-4-1 and Publications of IEC 1000-2-1, IEC 1000-2-2 in terms of electromagnetic compatibility levels In power supply systems and methods for measuring electromagnetic interference.

Standard indicators for power grids in Russia, established by GOST, are the following characteristics:

power supply - 220 V ± 10%
frequency - 50 ± 1 Hz
the coefficient of non-linear distortion of the voltage form is less than 8% for a long time and 12% - briefly

Stipulated in the document and typical problems Power supply. Most often, we have to deal with the following of them:

Complete loss of voltage in the network (no voltage in the network for a while more than 40 seconds due to disorders in the power supply lines)
Sailing (short-term reduction in the network to a value of less than 80% of the nominal value for a time more than 1 period (1/50 seconds) are a consequence of the inclusion of powerful loads, externally manifests itself as flickering lighting lamps) and bursts (short-term increase in the voltage in the network by more 110% of nominal at a time more than 1 period (1/50 seconds); appear when the high load is turned off, externally appear as flickering lighting lamps) voltage of different duration (typical for large cities)
High-frequency noise - radio frequency interference of electromagnetic or other origin, the result of the operation of powerful high-frequency devices, communication devices
Frequency deviation beyond permissible values
High-voltage emissions - short-term voltage pulses of up to 6000V and duration up to 10 ms; appear during thunderstorms as the result of static electricity, due to the spark of switches, there are no external manifestations
The frequency elevation is the change in the frequency of 3 or more Hz from the nominal (50 Hz), appear when the source of electricity is unstable, can not appear.

All of these factors can lead to the failure of the "fine" electronics, and, as often happens, to data loss. However, people have long learned to defend themselves: the filters of the network voltage, "quenching" jumps, diesel-generators that supply electricity systems in the disappearance of voltage in the "global scale", finally, uninterrupted power sources - the main tool for protecting personal PCs, servers, mini-PBX And others. Just about the last category of devices and will be discussed.
Classification of UPS

You can "separate" the UPS by different signs, in particular, by power (or application) and by type of action (architecture / device). Both of these methods are closely connected with each other. By power, the UPS is divided into

Sources of uninterrupted power low power(with full capacity 300, 450, 700, 1000, 1500 VA, up to 3000 VA - including on-line)
Small and medium power (with total power 3-5 kVA)
Middle power (with a total power of 5-10 kVA)
Big power (with a full capacity of 10-1000 kVA)

Based on the principle of operation of devices, two types of uninterruptible power sources are currently used in the literature. According to the first type, the UPS is divided into two categories: ON-LINE and oFF-LINEwho, in turn, are divided into reserve and linear interactive.

According to the second type, the UPS is divided into three categories: reserve (OFF-LINE or STANDBY), linear interactive (Line-interactive) and UPS with dual voltage conversion (ON-LINE).

We will use the second classification type.

Consider to start the difference of the types of UPS. Sources of backup type Made according to a circuit with a switching device, which in normal operation provides a load connection directly to the external power supply network, and in emergency translates it to power from batteries. The advantage of the UPS of this type can be considered simplicity, disadvantage - non-zero time switching to nutrition from batteries (about 4 ms).

Linear interactive UPS Made according to a circuit with a switching device, complemented by an autotransformer-based input voltage stabilizer with switchable windings. The main advantage of such devices is to protect the load from an increased or low voltage without transition to alarm mode. The disadvantage of such devices is also nonzero (about 4 ms) switching time to batteries.

Double Conversion UPS Voltages are different in that it is first transformed into the input to the input to the rectifier in constant, and then with the help of the inverter - again into the variable. The battery is constantly connected to the output of the rectifier and the input of the inverter and nourishes it in an emergency mode. Thus, a sufficiently high stability of the output voltage is achieved, regardless of the voltage fluctuations at the input. In addition, interference and perturbations are effectively suppressed, which is replete with the supply network.

Practically, the UPS of this class when connecting to the AC network behave like a linear load. The plus of this design can be considered the zero switching time to power from batteries, minus - decreased efficiency due to losses at twofold voltage conversion.

Physics

In all reference books, four types of power differ in electrical engineering: instant, active, reactive and full. Instant power It is calculated as a product of an instant voltage value and an instantaneous current value for an arbitrarily selected point of time, that is

Since in the chain with the resistance R u \u003d IR, then

Average Power period P of the circuit under consideration is equal to constant consideration instantaneous power.

The average for the period of the power of alternating current is called active . The unit of active power of the volt-amp is called Watt (W).

Accordingly, the resistance R is called active. As u \u003d ir, then

Typically, precisely active power is understood under the power consumed of the device.

Reactive power - The value that characterizes the loads created in electrical devices by the oscillations of the energy of the electromagnetic field. For sinusoidal current is equal to the product of the active current and voltage on the sine of the phase shift angle between them.

Full power - Total power consumed with a load (both active and reactive components are taken into account). It is calculated as a product of the standard input and voltage values. Unit of measurement - VA (Volt-Amperon). For sinusoidal current is equal

Almost on any electrical device is a label with an indication of either the full power of the device or active power.
Testing

The main purpose of testing - Demonstrate the behavior of the UPS tested in real conditions, give an idea of \u200b\u200badditional characteristics that are not reflected in the general documentation on the device, in practice, determine the influence of various factors for the work of the UPS and, possibly, help determine the choice of one or another uninterruptible power supply.

Despite the fact that the recommendations on the choice of UPS currently there are a great set, during testing we expect, firstly, consider a number of additional parameters that are worthwhile before buying equipment, secondly, the need to adjust the set of selected methods and parameters. Testing and develop a database for the future analysis of the entire path of power supply.

The general test plan looks like this:

Specifying device class
Specifying the characteristics stated by the manufacturer
Description of delivery package (availability of manuals, additional cords, software)
Short description external view UPS (functions rendered on the control panel and list of connectors)
The type of batteries (indicating the battery capacity, served / maintained, name, possibly - interchangeability, the ability to connect additional battery blocks)
"Energy" component tests

In the testing process, it is planned to check the following parameters:

The input voltage range in which the UPS operates from the network without switching to batteries. A larger range of input voltage reduces the number of UPS transitions on the battery and increases its service life
Switching time to battery powered. The smaller the switching time, the smaller the risk of failure of the load (devices connected via UPS). The duration and nature of the switching process largely determine the possibility of normal continuation of the equipment. For computer load Admissible interrupt time 20-40 ms.
Oscillogram switching to battery
Switching time from the battery to external nutrition
Switching oscillogram from battery for external nutrition
Opening hours B. offline mode. This parameter is determined exclusively the battery capacity established in the UPS, which, in turn, increases with the increase in the maximum output power of the UPS. To provide autonomous food two modern computers SOHO Typical configuration for 15-20 minutes, the maximum output power of the UPS should be about 600-700 VA.
Output voltage options when working from batteries
Impulse shape at the beginning of the battery discharge
Pulse shape at the end of the battery discharge
Range of output voltage UPS when the input voltage changes. Than this range is already, the less the effect of changing the input voltage on the feed load
Stabilization of output voltage
Output voltage filtering (if it is)
UPS behavior when overloading
UPS behavior when the load is disappeared
Calculation of the efficiency of the UPS. Determined as the ratio of the output power of the device to the power consumed from the power supply
The coefficient of nonlinear distortion that characterizes the degree of difference of the voltage or current form from the sinusoidal
- 0% - sinusoid
- 3% - distortions are not noticeable to the eye
- 5% - distortion is noticeable to the eye
- up to 21% - trapezoidal or step form
- 43% - the signal has a rectangular shape

Equipment

When testing, we will use non-real work stations and servers, but by equivalent loads that have a stable nature of consumption and the power utilization factor close to 1. As the main equipment that will be used during testing, the following set is currently being considered:

The main purpose of the uninterruptible power supply source (UPS) is to temporarily provide nutrition of equipment in power supply in power supply. Connect through the UPS computers are accepted everywhere. True, for many users it is a kind of "rule of good tone", and the practical meaning of this ritual escapes them. "Well, the UPS protects the computer from voltage jumps ...". Let's try to figure it out: what, what and how does the uninterruptible power supply protect?

According to the internal device and logic of the work, all UPSs are divided into three classes: passive, linear interactive and UPS with a double conversion. Accordingly, they cope in different extent with incidents in the power grid and belong to different price categories.

Passive (Stand-BY, VFD, Back-Ups, backup) Sources are the simplest and cheap. In them, the power circuit from the battery is usually turned off, and it starts only when the voltage is lost in the power supply. The switching time from the network to work on the battery is the tenths of the second, and the output signal during operation from the battery is noticeably different from the "correct" sinusoids. As a rule, at the entrance of such UPSs installed the simplest interference filter and high-speed fuse. The first partially smoothes impulse interference, and the second must work with a significant increase in voltage in the power grid. Passive UPSs are designed to feed home and office PCs. Small "failure" output voltage at the moment of switching to the battery computer blocks Food is not afraid.

Linear interactive (Line Interactive, VI, Smart-UPS) The UPS differ in the way that in them the battery power circuit is turned on constantly. With the disappearance of the voltage at the input "Uninterrupted", its output sockets are almost instantly switch to the internal converter - for the feeding devices, this transition is almost impaired. In addition, many linear interactive UPSs are able to automatically maintain the output voltage of 220 V. It is done in two ways.

While the network voltage ranges from 175 to 275 V, the AVR mechanism is triggered (Automatic Voltage Regulation, voltage authorizer). With the deviation of the input voltage by a value from 10 to 25% below the UPS rating increases the output voltage by 15%. With the deviation of the input voltage by a value from 10 to 25% higher than the UPS nominal lowers the voltage by 15%. If the network voltage goes beyond the limit values, linear interactive UPS switches to battery powered. In this mode, it continues to work until the voltage in the network returns to normal, or the battery does not discharge. However, such UPSs should not be considered as voltage stabilizers. The regime "stabilization" they have forced and short-term!

IN Double Conversion UPS (Double Conversion, VFI, Online-UPS) The output voltage is all the time output from the converter, the converter is constantly running from the battery, and the battery is continuously charged from the network. In fact, the input and output of the UPS are galvanically isolated from each other, and a stabilized voltage enters the exit. This is the most reliable, but at the same time a non-economic scheme. The UPS itself is expensive, large and heavy, the converter is strongly heated and requires cooling with a fan, and energy loss during the conversion is tens of percent.

A dual-conversion UPS is used only to power servers and computers in critical cases. In wide sale, such models are rare - usually they are supplied under the order. Most likely, you will get passive, maximum, linear interactive UPS to power the working computers.

The power of uninterruptible power supply is taken to indicate in Volt-amperes (VA, BA). To translate these values \u200b\u200binto more familiar watts (W), you need to multiply the power in the volt-ampere on the coefficient of 0.6. For example, the UPS with a capacity of 600 VA will provide power to the technique with a maximum consumption of 360 W. If you give a big load, current protection will work, and the "uninterrupted" will turn off. In practice, it is desirable to provide about 30% of the reserve in power. Thus, the most common UPSs by 600 or 650 VA are suitable for powering a computer with a real consumption of 200-250 W and a monitor that takes about 30-60 W.

If the placement of computers in the room allows, it is more profitable to use one powerful UPS instead of several small. On two office Computer It will take the "uninterrupted" with a capacity of about 1000 Wa. To power the three computers standing near, just one source with a capacity of about 1400 VA.

So what does the UPS protect?

With the restriction of pulsed interference from the network, filters in the power supply of the computer and the monitor are well coped. Nevertheless, two filters are better than one! Overvoltage protection is also important. If, for example, the zero wire in the shield will corrupt, the voltage can be a voltage of almost 380 V. In the power blocks of computers and monitors, in this case, varistors and fuses are usually burned. Repair a kopeck, but takes time. In theory, the UPS must respond to the voltage throw earlier than the fuses are burned in the technique connected to it.

However, data protection goes first. If the computer is disabled, all incomplete information disappears. The UPS allows either to save open documents and complete the work correctly, or translate the computer into sleep mode. Manually save documents easier. Turning to meals from batteries, the UPS begins to squeeze loudly. Once heard such a warning - check whether everything is saved. Further, look at the setting: or just turn off the computer, or move it into sleep mode.

To activate automation, you need to connect the control port (USB or RS-232, depending on the model) of the uninterruptible power supply to the computer signal cable and install the required software on the computer. Unfortunately, many users do not even suspect about such an opportunity! The operation of the UPS manages the built-in microcontroller. Its firmware (firmware) constantly monitors voltages and currents in external circuits, when turned on and periodically during operation performs testing of electronics and batteries. It also gives the control port on the current mode of operation, the state of the IPS components. By cable, these data go to the computer, where they are processed by the monitoring program.

To work with the UPS, it is advisable to use the program that its manufacturer offers. For example, for APC (www.apc.com) This is a Power-Chute program for IPPON (www.ippon.ru) - WinPower2009 and Ippon Monitor, etc. The program can be installed from a disk coming, but better download the most The fresh version from the manufacturer's website.

In the settings of the application you need to set parameters automatic shutdown. As a rule, two options are offered to choose from: or turn off the computer through a certain time After moving backup power, or do it for some time to the intended full discharge of the batteries.

How much time "Uninterborne" is able to work from the battery?

It depends on the battery capacity and power consumption. In most mass models, one battery voltage is 12 V and a capacity of 7 Ah. Theoretically, the UPS with such a battery has about 80 watt-hours. Simply put, it must feed the load with a capacity of 80 W approximately 1 hour, 160 W - half an hour, 300 W - approximately 15 minutes, etc. Really, taking into account the losses for the transformation, this time is roughly twice.

In sources with a power of more than 800 VA, two of the same batteries or one are usually installed, but more containers. Tables or calculators to determine time autonomous work With different loads for different models Listed on manufacturers sites. However, "Notevdka" can be taken that any model will be able to feed the load with a nominal capacity for itself for about 5-15 minutes. If you need to provide a sufficiently long meal of the computer from batteries, it is better to take a high power UPS with capacious batteries. It will work all over a third or a quarter of the rated power. But such a load, low for yourself, he will be able to supply the energy of half an hour and longer.

Network equipment (switches, routers, NAS) uninterrupted food is also useful. Otherwise, when the energy is disconnected, the network will immediately "fall", and the documents opened from network folders, Save will not succeed. You can power the switch from the UPS the workplace nearest to it, although it is more correct to put a separate "uninterrupted" small power for this.

The battery life is limited. As it is work, its container is steadily decreasing and after 3-5 years of operation drops almost to zero. Even before the indicator on the UPS signals the need to replace the battery, it becomes noticeable that the battery ceases to "keep charge." With each time the battery life is reduced. In principle, there is enough pair of minutes to save documents and correctly turn off the computer. When the UPS begins to disconnect even earlier, the battery is definitely time to change.

Replace the battery is easy. In the popular UPS of the APC brand and some other battery is under a removable luch or lid. To get to the battery in the IPP IPPON, SVEN brand and the design of it, it is necessary to twist the four screws on the bottom and disconnect the halves of the case. In the instructions and on the official website, you are unlikely to meet the description of self-disassembly and replacement: as well as manufacturers of printers, UPS manufacturers a significant share of revenues receive from the sale of "original" batteries with their installation in authorized SC.

Nevertheless, almost all computer stores sell sealed lead-acid batteries of the most running sizes. Mark and role manufacturer do not play: it is quite standard products. Pre-open your "uninterrupted" and find out what battery it is installed. For most of the "Office Class" UPS (500-700 VA), batteries with labeling 12V 7AH with dimensions of 151 × 94 × 65 mm are suitable. Setting new battery, Try tightly dress terminals on the contact petals of the battery. If the terminals weakened, they can be carefully filtered with pliers.

After installing the UPS battery, it is desirable to calibrate so that its firmware appreciates and remember the parameters of the new battery. Fully charge the battery during the day. After that, remove the plug from the socket so that the UPS moves to autonomous food. Give the battery to completely discharge until the "uninterrupted" does not turn off myself. It is better to use a computer as a load (although in extreme cases and it is permissible), and several light bulbs with a total power of about 300 W. Then again connect to the network and turn on the UPS - let the battery charge, and the device will continue to work in normal mode. In addition to calibrating the device as a whole, such a procedure is both a "training" of the battery. After the full cycle of "discharge - charge", the battery begins to maximize its container.

Why are telephone (RJ-11) and network (RJ-45) sockets made on many UPS?

Neither phone nor the local network "Uninterrupted" is not needed by definition. Just as a "bonus" in one case with the device, the passing filters of pulse interference for the telephone line and the network are installed. Connect one socket with a handset on the wall, and turn on the telephone. If a high-voltage tip appears in the telephone line, for example, during a thunderstorm, the filter will smooth the voltage throw and protect the phone.

Embossed power supply is one of the main problems of the failure of household, office or industrial equipment. Despite the fact that nozzles arising in the electrical network are periodic, they have a detrimental effect on the components of modern electronic devices connected to the outlet. To protect the critical equipment or storing data when the supply voltage disappears, uninterruptible power sources are most common.

The main schemes of work and scope of uninterruptible power sources

The assignment of the UPS is to ensure the correct operation of the load with sharp "failures" or "bursts" of voltage, as well as ensuring the short-term offline operation of the connected equipment with the full shutdown of the electricity. Modern uninterruptants are divided into three classes:

Backup or offline
Linear interactive
Double energy conversion

Their design and functionality are somewhat different, but, how to use a smoothie, everyone can understand.

Why do you need a reserve UPS? The main scope of its application is the protection of household computer and multimedia equipment. The scheme of its work is extremely simple: the load is powered by the network, and when the voltage disappears in it, the device switches to battery mode. The switching time between the types of functioning is nonzero. It is relatively inexpensive and will allow protecting equipment from minor voltage drops and short-term stress disappearance.

The advantages of the Linear interactive type UPS are more smoothly stabilizing the signal and the possibility of working in a wide range of input voltages. Such devices do not allow to adjust the frequency of the signal from the power supply, in the same power mode from the battery cells, may produce "pure" or approximated sinusoid. How can I use Line-Interactive uninterruptible? It is great for protecting monitors, system units, LAN nodes, workstations, computer peripherals and other devices with pulsed blocks Food, which makes it excellent.

The most perfect equipment protection - UPS with a double energy conversion. But what is valuable in uninterruptible designed according to the Online scheme? It is characterized by instant switching between operation modes and the independence of the signal parameters at the output from the parameters at the UPS input. Therefore, this type of UPS is designed to switch equipment, especially demanding power to the quality of the power supply. Among uninterruptants online topology, based on the scope of their application, you can select the following types:

Alternative protective equipment options

Many wonder: Does the uninterruptible need, if the voltage in the network does not disappear, but simply "jumps"? Does you need a uninterrupted computer in that case? The answer to these questions may be a look in the direction of voltage stabilizers. These devices allow you to adjust the signal in a very wide range, feeding the voltage of this level to the load input, which was set by the user. This is the main advantage of these instruments. The main disadvantage is that the stabilizer ceases to work simultaneously with the disappearance of the voltage in the power grid. The main problem of stabilization devices is the inability to ensure the autonomous workload. Therefore, it is important to clearly understand what the equipment must be protected: from fluctuations in the signal level or from frequent and short-term power outages. In the first case, the output from the situation will be the voltage stabilizer, in the second, the source of uninterrupted power supply, the purpose of which is somewhat extensive.

But what to do if the signal level in the power grid is relatively stable, but there are long-term power outages? Out of such a situation can be the acquisition of a diesel generator. They are produced with different power ranges and can be applied to maintain both domestic and industrial facilities. There are models on diesel fuel and on gasoline. The device starter can be both manual and electric. The advantage of using such an installation is that it can provide for a long time of autonomous operation of equipment with interruptions exclusively on service or refueling. This technique is compact, easy to maintain and easy to use.

The operation of DSU is not deprived of a number of shortcomings, they can be attributed to them:

The inability to independently transition to the power of the load when the voltage disappears in the power supply network;
Noise in the process of work;
The presence of exhaust gases;
A large number of consumables (candles, fuel, etc.)

Complex solutions for protecting electronic equipment

To ensure maximum protection of telecommunications, server or industrial equipment, the use of one type of devices may not be enough. Therefore, the most optimal decision It can become their combination. For example, the UPS for emergency lighting will not provide a proper level of autonomy. This task is solved by the consistent connection of the uninterruptible power supply and DGU. Why do you need a uninterruptible in such a scheme? To filter the voltage and ensure the autonomy of the system, until the generator starts and does not enter the operating mode.

Why and how can you use a uninterruptible pair with a voltage stabilizer? For the correct operation of the equipment in the sections of the power grid, where private voltage differences are observed, which are not accompanied by its full disconnection. Due to this, a significant reduction in the construction can be achieved: an inexpensive stabilization device will ensure efficient signal adjustment, and the UPS of the average will allow achieving an acceptable level of autonomy.

Select UPS

First of all, attention should be paid to the following characteristics:

Maximum power, measured in Volt-amps "VA" and watts "W" (the choice depends on the power of the computer and the monitor than they are more, the more should be the figures from the UPS);
Battery life with full and half load (good indicators 5 and 15 minutes);
The input voltage range (under what limits will be cope with the UPS without using the battery, it is desirable 180-250 volts or wider);
The number and type of sockets for connecting devices (there may be ordinary "Euro-sockets", and there may be special computer).

When buying a UPS, it is better not to save, otherwise you will have to regularly pay extra (on too frequent replacement of the battery or repair), and whom will it want?

When choosing a uninterruptible power supply, you can follow simple rule: do not buy cheaper $ 90.

There is one exception of this ruleI described in comments To this article ().

Starting from $ 150-200, there are even more reliable models that work on a more advanced principle, but this price is already available not to everyone.

UPS compatibility and computer power supply

Before buying a UPS, one important point should be known, which is not often said about:

Some computer power supplies incorrectly work with the UPS!
You can clarify the seller, saying the power supply model.

In one of the following IT lessons (but already on more high level preparation) We will look at why this is how and how to avoid this problem. If the question does not tolerate, then contact the comments to this article, I will try to help.

Connecting a network filter and UPS

Connection is pretty simple:

The network filter or UPS turns on the power block, monitor and other power cord external devices (scanner, printer, etc.).
The cord fork of the filter itself or the UPS is connected to the outlet of the home electrical network.

If you are using the UPS, the network filter is not necessary, except to increase the number of outlets or as an extension cord.

Note:the laser printer cannot be connected to the UPS, as it has too much power, often a special outlet is provided for it, which does not feed on the battery, but has a filter from interference (on the last photo in the article such a socket is painted with white).

Summarize

The main idea of \u200b\u200bthis lesson is that the network filter and the uninterruptible power source - things needed and should be used with each computer. If you still do not have these devices, then surely buy at least a network filter!

So, with important additions figured out, now you can go to the sixth IT lesson. He is already on the way, follow the news! Here is a link to receive the news of the site for mail.

Video Supplement

Today, as an addition to the video from the company "Chip and Dip" about uninterrupted power sources:

P.S.Isn't it too complicated information? I have a request for you: Write in the comments to this article, which is not clear, I will adjust!

Share with friends:

Communication and exchange of experience (146 comments):

And I'm abstract, because The article is written very superficially.
UPS cost from 600 UAH. Normal, inexpensive, reliable ARS. Alternatives in terms of durability and no propestory and which is actually depicted in the photo in your article.
And about the protection of phone lines, Lan you are generally silent?

Network filters? For 30 UAH there will be a cheap Chinese nonayimov extension. How do you write " best defense"Provide ARS, Belkin worth 150-200 UAH. And the ability to turn off the power separately in each rosette as in Sven Pro? And again the protection of tel. and lan lines?

And about the third type of protection - the stabilizers why not say not said?

The article is designed for housewives with which the UPS will only need to have to keep the page in classmates.

No offense.

I love criticism and welcome (if it is reasonable, adequate and constructive).

I will answer your comment, Valentine.

1. UPS from 600 UAH
UPS, which is depicted in the photo serves me for 11 years without replacing the battery and is no longer produced.
There are UPS, which costs $ 80 (640 UAH.) APC BK500-RS Almost like mine, he does not have the protection of telephone lines, but the model mentioned is really good. Can be considered this model except from rule.
The next price of the BK500EI model is already more than 800 UAH (she and voltage range is wider and connected to the computer via USB and telephone line filter).
(Link to this note is added to the article.)

2. About the surface of the article.
Most likely, you did not pay attention to the description of the site and the category of this article.
I will explain: this site is a guide from a novice to the professional and the complexity of the material grows gradually. This lesson refers to the category of "Level 1 Newbie", so I did not complicate the material. When you get to level 2 and 3, then we will consider in more detail different components, including those mentioned in this lesson.

3. "How do you write the" best defense "will provide ARS, Belkin worth 150-200 UAH."
Where did you see that I advise "Belkin worth 150-200 UAH"? How did the phrase about the UPS "not buy a cheaper 90 $"? This is about network filters I said "the best protection - models from $ 12" to which the Sven relates, Platinum Pro.

4. Pro Protection of phone lines, separate switches for outlets, stabilizers, etc.
Far no longer need a telephone line protection, but in the recommended price range it is. As an email, I can explain the effectiveness of this protection "for a tick" (in this price range).

I have a network SVEN, Platinum Pro, I can say on my own experience that the presence of individual switches is not necessary for everyone, this is not the main characteristic.

Stabilizers I did not mention, as they are applied less often (again, based on my practice), and the determination of the need for them and even more so their choice is a separate topic.

The main thing that should remain at the newbie in memory after this article is the importance of the need for at least a network filter, as well as the idea of \u200b\u200bthe possibility of acquiring the UPS.

And I'm not offended by that, on the contrary, thanks for criticism!

It is not entirely clear to me, due to which the network voltage is filtered, a network filter. It may be in this network filter there is some kind of scheme except five sockets for forks. My computer and other consumers are powered by voltage stabilizer. The question is how you can connect the car battery to the voltage stabilizer to protect yourself from unexpected voltage shutdowns.

Of course, Victor, in the network filter, in addition to sockets, there are elements that reduce sharp voltage jumps (which last the fraction of seconds).

Directly connect the car battery to the stabilizer will not work. Additional special schemes are needed: one to convert the battery voltage (+ 12V) to the computer power supply voltage (~ 220V), the second to track the lack of voltage in the network and switching the power to the battery with the converter. It's all in a simplified form.

I do not think that it makes sense to try to make such schemes yourself, since cheaper, reliable and safer use uninterruptible power system (UPS).

I bought an UPS with calibration 425. Explain, please, whether I connected to the rear panel of the UPS system and monitor. Battery Backup 3 nests on the left, connected 1 super monitor, 2-below its system. Whether I did the right thing that I connected the monitor and the system system to the output of the UPS with backup power. This is all on the left. On the right there are 2 nests of the UPS) only with voltage filtering. In these nests, I did not install anything and also on the right under them there is an input network connector, this connector with a fork connected to a network filter outlet. Please email to my e-mail. There were no drivers and instructions in the package, I will go to the store to understand.

Hello, Lyudmila.

Since the exact description of the model of your UPS is not, I can answer only focusing on the comment on which I can assume that you have an IMP-425AP or IMD-425AP model. If so, then the monitor and system unit You connected correctly (in the photos from the site. The inscription "UPS + SURGE").

Instructions, of course, should be complete with the UPS itself. If the store is rehabited, you can download the instructions with a href \u003d "http://www.pcm.ru/" target \u003d "_ blank" REL \u003d "NOFOLLOW"\u003e official site.

Check with the model designation at the UPS itself, if you are questions - contact.

Thank you, Seryozha, for a quick answer! The full name of my Ipple-interactive UPS. Imperial Oops, with display. Improved protection. The store gave instructions and cable with USB. When I connected this cable, it's good that I have a lot of slots on the rear and front panel of the Systemizer. The battery readings appeared 1 pc. HID UPS Battery, Him. PDAC. Energy supply - power supply. I am confused by what is written about the battery: the date of manufacture 12/23/2009. Do not the battery industry? Drivers were not. I downloaded from Ineta Prog Upsmon, but she writes, it is impossible to connect to the UPS. I have a 4-core comp, Athlone 640 3.0 GHz, GT 440 1 GB video card (128), 750 GB screw, 4 GB RAM. BP-400. The computer is seized for 2 years (warranty). All data from AIDA. It seems to me that the UPS with 425 VA, 255 watts for my computer is weak, although enhanced protection is written. Mostly the computer was taken for games. I look forward to your advice. Sincerely, Ludmila.

Indeed, for your configuration, the power of UPS 255 W is small.

Here is an approximate calculation of the power of your PC:
ATLON 640 processor - up to 95 watts
Video adapter GT 400 - up to 65 W
System board - up to 35 W
Hard disk - about 12 W
DVD - about 10 W
RAM - up to 10 W
USB devices etc. - up to 10 W
Total for the system unit: 237 W
Add 20% in stock and get 285 W.

Do not forget about the monitor (which diagonal?) For 22 inch monitor 30-45 W

TOTAL, system block + monitor - up to 330 W In the maximum load!
Real figures can be lower, but the UPS is desirable power at least 300 watts.

P.S. I would pay attention to the computer power supply. If the manufacturer is too "economical", then the real maximum power may be far from 400 watts, but somewhere 200-300 W. If the BP is high quality, then there should be no problems.

Regarding the date of manufacture, I will give an excerpt from the instructions for the UPS:

6.3 Terms of long-term storage UPS
6.3.1. At the storage medium temperature from -15 ° C to +30 ° C (from +5 ° F to +86 ° F), it is necessary to recharge the UPS battery every 6 months.
6.3.2. At the storage medium temperature from +30 ° C to +45 ° C (from +86 ° F to +113 ° F), it is necessary to recharge the UPS battery every 3 months.

Those. It can be concluded that two years of storage without recharging could well reduce the battery life. How much is reduced, it is difficult to say.

Monic Acer 19 *, I think for a close distance on the table, it is ideal, large monics strongly affect the eyes (close distance to the comp. Table). Upgrade can be made only after 1 year, warranty for 2 years. But my computer is very quiet, all games black OPS, crisis, metro, etc. pulls without problems. WDC WD7500AARS-00Y5B1

It is a tempo. After ks 1.6. If I only change, then the south bridge of Mammy ASROSK 68, I believe that it is weak for my company. Although the upgrade is better not to do, and every 3 years buy a powerful gaming computer. Auch- I think this is the temperature of BP.

No diagonal influences vision, and the brightness and method of its adjustment, which was implemented by the monitor manufacturer (a separate article on IT lessons was scheduled for this topic).
Also affects the fatigue size of the interface details, which depends on the screen resolution for the current diagonal.
But we were distracted, the question was about the power of the monitor 🙂

At the expense of temperatures - everything is fine, but it was originally about the quality of the power supply.
You can compare voltages (especially +12 V) with minimal and maximum load. But it is better not programmatically, but in fact (tester), only in your case it is not possible (the system unit is selected).
If the voltage deviations are quite large, then such a power supply is not trusted.

Good afternoon, I will ask with a question on the UPS and interference (running background waves) launched on the monitor (LCD) because of it, which are noticeable mostly in the last games (crisis 2, Witcher 2, Sniper Elite, Batlfield 3)
Monitor- ASUS 24T1E-H
UPS- EP1500.
Socket is not grounded.

Diagnostics:
1. When the monitor is connected, the interference is not detected to the free socket. (UPS on the distance ~ 1 meter from the monitor)
2. When connecting to a network filter outlet in 1 plug, the power cord is inserted in the 2nd monitor power cord - interference is detected.
3. Connecting the power of the monitor directly to UPS (connected to the outlet without ground) - interference is detected.

P.S.
1. A PC with a block is connected to this UPS. power Antec. HCG 750.
2. These interference is noticeable only in powerful 3D games, when watching movies and work in these interference, there is no interference.
3. With all tests, UPS did not move and is located at a distance of approximately 1 meter. (I did not see the point of rearrangement, since it was not detected to the straight to the network.)
4. Interested to connect to Oops a Network Filter APC P1-RS (which by X-Cam. The manufacturer filters E.M. interference), and the monitor power cable has not helped to it.

Please tell me how to get rid of the interference by connecting the monitor with the system to the UPS.
Conduct grounding will not succeed.

Thanks for attention.
With respect, Chernyshenko Vladimir Anatolyevich.

So, still, about stabilizers - as far as I understand, they are something intermediate between the network filter and the UPS, only here, not all the UPS have the functions of the stabilizer. But in what situations stabilizers are needed in practice? Do they perform the function of the network filter or exclusively stabilize the affected / overestimated voltage?

This is the situation - from the air conditioner blinks the light in the apartment and the computer in the games (i.e., when loaded), it happens to the stealing - will the stabilizer solve this problem or do we certainly spend money on a more expensive UPS?

Alexey, first clarify two questions:
1. The light blinks periodically for short intervals (up to 1 second), or a longer time the light remains dim (more than 5 seconds), and then returns to normal?
If periodically and up to 1 second, the UPS should cope.
2. Do I realize that you already have a UPS and, despite this, a computer with short (?) Voltage jumps reboots?
At the expense of stabilizers. Their purpose is to lead the voltage level to the norm (220 V) and hold it a long period of time. If voltage jumps are rare and short, and mostly voltage is normal (about 220 V), then preferably a good UPS.
- 1. The light blinks on a split second.
  
  2. No, the UPS is not available.
  
  In general, I would like to understand what is called, the reverse continuity between these three devices is a filter, stub and UPS. Those. Will there be a stabilizer to perform functions incl. Network filter, and UPS perform a network filter and stabilizer functions? Or, if I want to provide maximum protection, I need to buy a network filter, connect the stabilizer to it, and from the stabilizer to power the UPS?
  
  And another question is related to power supplies - as far as I know, the expensive models of BP are already embedded by various systems of protection, filtering and stabilization of voltage - is it and if yes, then how this correlates with the equipment discussed by us (Filter, Stub, UPS)? And how to determine the presence of such a functional in BP.
  
  Thanks for answers.
  - BP, UPS and stabilizer must contain a filter, but in cheap models the manufacturer "misses" it or greatly simplifies.
    Dear UPS contain a filter and stabilizer. You can find them on marking "LINE-INTERACTIVE" (interactive). For maximum (!) Protection on servers use UPS "With Double Conversion" or "Online".
    The stabilizer is mainly used to feed household equipment (when the voltage is strongly leaving the standard or in the network there are frequent voltage jumps). For PC, a preferable is a good UPS, if necessary, then with a built-in stabilizer.
    The range of input voltages (and for BP too) is indicated in the specifications.
    - It turns out more profitable to take some FSP Aurum CM 550W with a filter, a stabilizer 90-264B and all kinds of protection (OCP, OVP, SCP, OPP, OTP, UVP), rather than spend on expensive filters, stubs and UPSs. Who does not need a safety policy of the work done in the form of a battery, of course.
      
      Apparently, the reboot of the computer is not related to the blink of light, at least dependences I did not follow - I can leave it overnight, and in the morning wake up and discover that he rebooted. At the same time without blue screens And other errors, just sharply goes on overload and that's it. It happens not often, but strains. Can this be connected with the power supply? I have FSP Hexa 500W 80 Plus.
      - A good stabilizer with an input range of 90-264B, and even at an affordable price is problematic to find.
        I repeat, it is better to take a good BP (from 40-50 cu) + good UPS (from 80-90 cu).
        
        At the expense of the periodic reboot of the computer, it is impossible to say the off town. Look at the "System Journal".
        There may be bp, and RAM, and the joint venture, and railway, and the video adapter ...

Hello, please tell me what is the reason. The computer turns off overnight, and in the morning it does not work, turns on only when replacing the cord from the system to BP, while the BP itself is working and the other computer works with that cord that they replaced and the same BP

Hello Tatiana.
Judging by the description, it looks like a bad contact between the cord and the connector in the power supply. It is very rare, but I had a similar case in practice. If everything works well with the second cord, then leave it and the problem is solved if the problem is repeated, then try the following option:
It is necessary to check (visually) contacts on the pins in the BP connector, if they are oxidized or dark, then carefully cleaned. You may have to choose a cord that will work well in this connector of your power supply.
But these recommendations are relevant, only if you described the problem completely.
1. confuses the phrase "Cord from systemic to bp". May be "Cord from the system unit to the UPS"? Where is the cord connecting from the power supply in the system unit?
2. Is there a network filter and / or UPS?
3. In the morning, when the computer does not turn on, we tried to simply pull the cord from the outlet, then connect it back and press the power button?

Good afternoon, Seryozha! I already addressed your help and thank you for your professional answers. Sorry, again you need your advice: the battery icon from the UPS 99% (left) is shown in the tray. Battery name
HID UPS Battery, PBAC chemical composition, Energy supply: Network from the network, charging. Manufacture date 12/23/09 Question: can change the battery, time using UPS 2 months. Sincerely, Ludmila.

Hello, Lyudmila.
Given that the battery is 2.5 years (from the moment of production), the wear by 1% is a very good indicator. So far, there is no point in changing the battery, post for her condition in the next 2-4 months. If in 2 months the condition of the battery will deteriorate by more than 5%, then it is worth thinking about too fast wear. But now there is no reason.

Good day, Sergey! As always, I hope for your professional answer! The UPS stands, the monitor and the system are connected to it, then connected to the network filter, the power filter is already connected to the outlet. Question: With a thunderstorm, if there is an UPS, is it necessary to pull the plug of the network from the system and remove the plug from the power filter.?

Hello, Lyudmila.
During thunderstorms, first of all it is necessary disable the cord by which you are connected to the Internet (Wit a pair of network card or router, telephone cable from the modem). After disconnecting the cord, it is advisable to place away from the connector and the device itself (computer, laptop, router, modem).
Why first? Statistics show that most often during a thunderstorm fails the network card and / or the PC motherboard.

In the second place is desirable disable from outlet A device that isted computer (filter, UPS or power supply cord). Additionally, pull the cord from the power supply no sense. It is also advisable to place a disconnected plug at a distance from the outlet.

At all, during the thunderstorm, it is advisable to disable From electrical network all devices, especially in a private house.

* After disconnecting the cord, it is advisable to place away from the connector and the device itself (computer *, - did not know!

* It is also advisable to place the disconnected fork at a distance from the outlet * -. DONT KNOW!

So, the UPS will not save the computer during a thunderstorm!

Thank you very much, Seryozha! So I will do how you advised!

Good morning, Seryozha! You for me like ambulance For my company. On this battery, right-click: Power Properties, there is a tab: Schemes Control Schemes, now list:

I trust you, so I really need your advice! Sincerely, Ludmila

Thank you, Seryozha! Everything is clear and understandable! Today, the light turned off, the UPS filed, it was a message on the monitor urgently change the battery, the charge was 77%. Somewhere min 5 There was no light, the UPS did not disabled, the cut, and then the light turned on and the battery began to charge up to 96 percent. Sometimes 99% will appear, but already less often. Five months passed. After buying a UPS. The UPS itself does not need to change, only batteries, right? And what value of these batteries, I have only one. When will I buy, how to determine the year of the battery? Sorry again, I no longer contact someone, I do not trust sellers, it is advisable to sell the stuck goods.

You can not yet on the topic: in May 2013, the 2-year warranty of my systemizer ends, the case of which is seated with stickers. Will I act correctly:
1. Note a specialist to brush from dust and change all the coolers and radiators on the expensive.
2. MOVA I have a budget cheap, there the southern bridge is heated in games in the summer of up to 65 degrees, is suitable for her video card Jifors GT 560 DDR5 (I know that 256 bus is better than 128) not on 1 GB, but 512 MB, but Tire 256.
3. I will not add the RAM, since I love XP and I don't want to change to another OS, but 4 GB I will have enough (for COP and D.Komp games)
BP I have 440 GB I think the new video card will not stand, change the 650 PB chief.
Your advice: Will my mother will withstand this upgrade, percents I like AMD 4-kernel 640, does not heat. Can only change the cooler and the radiator on the video card? I need your advice as a specialist. Sincerely, Ludmila.

The discharge of 20% in 5 minutes is quite normal, you can not change the battery. When in 5 minutes it will be discharged to 20%, then you can think about replacing.
Interestingly, the message "Change the battery" was output from OS or from the UPS manufacturer?
How does the UPS feed? The instructions for your specifies the following:

Rare Bip signals (once in 2 seconds) - backup power from the battery.
Frequent Big Signals (2 times per second) - Low charge degree of battery.
Continuous beep - overload.

Of course, the smoothness itself is not needed - only the battery.
To find out the cost, you can see here: http://hotline.ua/computer/akkumulyatory-doma-ibp/ (as I understand it, you live in Ukraine).
Presumably you have a battery CSB. GP1272 F2 or Yuasa. NPW36-12 (maybe NPW45-12), accurately check when disassembling the UPS (see the instructions). The reference to the first http://hotline.ua/computer-akkumulyatory-dlya-ibp/csb-battery-gp1272/ talks about the price range 180 - 235 UAH.

date of manufacture Specified on the accumulator package:
- CSB is a circle with an arrow;
- Yuasa has numbers near the Red Terminum, the first two to the year, the third and fourth month (09021830 - February 2009).

Hello ... Today, something happened to the PC and he hung ... I had to turn off straight from the outlet (I didn't help anything .... After this, I backed it on it (and when all the cords flew well), but IPP now I can not turn off (( Button and everything .. after, and it does not turn off .. it turned out from the outlet so it is frightened and everything ... What I just didn't do ... very strange (why did it happen? I am afraid that it turns off the light, and it will squeak 3 hours and I I can not turn it off

It is difficult to judge about what happened from your words, too little information.

1. When you turned off the computer, did you try to press the power button and keep more than 5 seconds (as indicated in class 6)?
2. Is your computer now turn on and off normally (it is the computer, not the UPS)?
3. Leave the UPS included for several hours, then repeat the shutdown process (according to the instructions from the sixth lesson).

If something works not as it should, describe detail Your actions and result.

Hello, Sergey!
Recently, my computer was put in order with the master and he issued such a note-information: "Why do you turn off the power? In the same place in Bios, the battery ((he meant probably battery ??)) it costs, may spoil ... "
I feed the computer, monitor, columns (active) through the extension to 5 sockets with a switch. Completed the work, everything calmed down, climbed the switch ... and so easily it becomes)))) you can sleep quietly)))
After completing the computer, there was a computer "economy", and I see: a mouse under nutrition; Monitor in the stand-Bae, the diode is glowing; The keyboard indication is glowing; And bliss, resting, only the main block (but also in this is not fulfilled).
In general, I still continue the power to turn off the switch on the extension. And the doubts are allowed))))

Hello, Valery!

Indeed, the system unit does not rest when the computer is not disconnected from the network (with a button on the filter or the UPS button). Inside the system unit there is a standby voltage required to control the state of some devices (network card, modem). The power supply itself, of course, is also under voltage, although it consumes a bit.

I am myself always turn off the computer completely (switch on the extension filter before UPS). Really quieter and nothing flashes 🙂
In addition, in case of malfunctions in the electrical network (lightning, inattentive electrician, etc.), the minimum probability of damage to the computer and peripheral devices.

At the expense of a battery packing BIOS chip: this is not a battery, but a lithium battery Type CR2032, its main task is to store the settings in the chip, the service life is 3-6 years, costs less than 1 cu Why save on it?

Defoable time, Sergey. This is what problem. What is the problem. Bucked 5 days ago I bought a new computer (Quadro AMD FX-4100 (3? 6) / 4GB / 1TB / GeForce GTX.5500ti / 1GB / DVDRW / CR / GLAN / Miditower). And everything was well smoothly until I turned on one of the "heavy, large-scale" buh (Dragon Age, Aion, and so on). The luck lasted for 40 minutes, after which The computer suddenly began to reboot and turned off in the process at all and some time did not include any time. And this happens every time when you start such games, the rest of the time the latch is ideal. In fact, the store where the computer was bought, it was tested and assured that everything is fine with him. I did not believe them for the word and gave the computer to the diagnosis in another computer interior (independent, so to speak), but also there I did not reveal anything, no errors, failures, overheating, etc. . Specialist who was engaged in my computer suggested that the problem is in my home power grid. What will you advise in this case? Is the problem really in this? How to solve it? What kind of uninterruptible power source (I understand that if the problem is in electricity, it is necessary that it is necessary will you buy?) Need to purchase (do you need? And will it help?), what power, etc. (and, if possible, not really expensive), I myself, as you probably already understood, I will not mean anything ... I will be very grateful if you help me with a good advice!

Hello Svetlana!
If the computer restarts and turns off only when launched GamesT. i would have checked on overheating.

Perhaps the conditions when checking in the computer cabin were cooled than you at home. Is it worth the system unit at the battery, are the ventilation openings are not covered with the side (for example, the side vertical surface of the computer table or pressed to the sofa), etc.?

Run the program PC-Wizard (IT lesson 12 and 13), go " Voltage, Temperature and Fans"And look at the temperature immediately after switching on, and then compare with a fully loaded processor and video adapter. First, check the temperature of the video adapter.
If you make sure that nothing is heated more than 60-70 degrees, Only then will be able to think about the problem of power supply.

Check, then write me the result, then we'll figure it out in more detail.

Good day,
I have a question similar to the waves on the monitor. Waves appear in the last toys. And so there is no them. If the monitor is disabled from the UPS and turn on the filter - everything disappears immediately, it seems why does he need me then?. This system is: 500W power supply. Video, percent, monitor and all other in the amount of no more than 300W at maximum loads. Uninterrupted such Powercom BNT-1000AP (600W). Already changed the filters and all that - all, too, if the monitor is directly, then there is no waves.
Thanks in advance.

Hello, Alexander!
A similar problem (which is described above in the comments) Vladimir decided as follows:

"Most likely the case is in the earthen loop. The land, except for the power supply, goes and the VGA cable - it turns out a loop, where there is too much dirt on the VGA cable screen. In the load increases energy consumption, the current on the cable flows high, it is also more in the land, so there is no interference. When I turn on in different sockets, no loops, therefore everything is normal. I don't see any reasons for this situation.

From all sockets in the network filter. In our apartments of the former USSR, there is usually no land for ordinary outlets. There would be an earth, there would be no problems.
He took a tee without earthlings, connected it to Oops, and the cable from the monitor and the problem disappeared.
Now the PC and the monitor work from UPS without any problems. "

In addition, pay attention to the type of cable to which the monitor is connected to the video adapter, if it is a VGA cable, then it is very susceptible to interference and it is better to have it away from the UPS and the high-current lines. If possible, it is better to use a DVI cable.

Good evening, Sergey! Thank you for answering! Made everything you wrote.
The only change that has made on its own initiative - for the computer itself used another network filter (+ other socket), everything else (monitor, columns, a table lamp, etc.) left at the same place. Direct: almost one and a half hours of the game without rebooting .

maybe it was worth playing longer to make sure that there would be no reboot, but ...
Can a change of socket and a network filter be a solution to the problem?

Suspiciously that the voltage instead of + 12V is displayed 10.75 V.

Go to the BIOS and check the readings in it (model of the motherboard you did not report, so I can't call the name, you can see in the instructions or in turn goes to each section).

Sergey, I'm sorry, this is again I ... nothing foreshadowed trouble ... games have not been running ... The computer turned off and the following rebooting appeared in the reboot process:

Power Supply Surges Detected During The Previous Power ON
ASUS Anti-Surge Was Triggered to Protect System from Untable Power Supply Unit
Press F1 to Run Setup
Press F2 to Load Default Values \u200b\u200band Continue

do not help clarify the situation? Please!)

The phrase "Power Supply Surges Detected During The Previous Power ON" is translated "The races of supply voltage during the previous inclusion are revealed."
By pressing F1, you will go to the BIOS settings, and pressing F2 will reset the BIOS settings and the download will continue.

In order not to appear "ASUS Anti-Surge Was Triggered to Protect System from Unstable Power Supply Unit" when downloading, you can turn off the Anti Surge function in the POWER section.

But it will not solve the problem.
1. It is necessary to deal with the supply voltages of the power supply (in the previous my message I drew attention to the deviation from + 12V)
2. Do you have a light at home periodically flashing? Do you know how much the stress on the network differs from the set 220 volts?

good evening, Sergey! I have a hurry to report, what ended my misadventures with a new computer)
A little less than a month was on a business trip, upon returning from which he decided to achieve justice, solving my problem. In the second time, he gave his computer to the diagnosis, once again they informed me that he was in perfect condition. And at that very moment, When one of the employees wanted to turn off my computer (and all this time he worked, they were repeatedly tested) and touched it before the place on the rear panel, where the power supply is located, this very employee struck the current (rushing, of course) and the computer again began to reboot As such a thing has been at home. In general, the problem was, as you assumed, in the power supply, something there with grounding)!
Thank you very much for the advice))) and Happy New Year to you)

In computer technician, you can often find such unstable problems.
Glad for you, Svetlana, that such an accident helped solve the problem on the spot 🙂

Sergey, Greetings! Interestingly Your opinion. The following is the following: Systemsman isted from a network filter. Difference from the outlet 217-220 V. In turning on the computer during the boot of Windows (the moment when the blue squares run) for some reason these squares stop and loading gets up. Helps shutting down a power pilot and then everything loads fine. What is the problem ???
And the second question: if the release of the UPS is only one, is it appropriate to use a network filter at its output as a breeding?

Hello, Paul!
Computer hang occurs every time you turn on? Or maybe only after recovery from the sleeping / waiting mode?
Is I realized correctly that the "Reset" button does not help, only power off helps?

At the expense of the UPS, I would use a regular extension with multiple sockets (in order to avoid the possible effect of the filter chains on the IPS output circuits). And if we are talking about the choice of UPS, it is better to immediately buy a model with several outputs to avoid unnecessary adapters and extension cords (they potentially reduce electrical and fire safety).
- Yes, the hanging happens every time they are turned on. These were not, it is necessary to turn off the power filter to the network filter, after switching on, the computer is loaded normally. That's such a primitive (
  - Definitely determine what the problem is difficult. It is necessary to carry out detailed diagnostics.
    The first step, I would drop the BIOS settings to make sure that they are not the cause. Then try to turn off the computer (through the "Start" menu, and not the power button), do not turn off the filter power, wait 30 seconds (so that the HDD pancakes stop), turn on the PC, to see if it will load without freezing. Remember the result.
    The second step, I would check the actual voltage values \u200b\u200bissued by the power supply (via BIOS or using the PC Wizard program. It is desirable to check the voltages with different loads (CPU and video adapter). Deviations from standard stresses must be minimal.
    I would repeat the situation on the net version of the same version (you have to reinstall Windows or install on the second hDDIf there is any). This step may be problematic, but it significantly narrows the circle of search.
    After these steps, you can do the first conclusions.

Good evening, Seryozha! I decided not to wait for the warranty on the sidewood for 2 years as 2 years old and send to those skilled in the dust and change all the coolers to new ones. And immediately change, as you advised, video card on jiffs 560t DDdr5 Tire 256 bits. And at the same time I change the BP on a more powerful due to the video card. But I have such a question: my UPS is now pulling a computer, without light 8 min. But whether he will pull when I put this powerful video card and BP at 750, if it is 425 via, i.e.e 255 watts. I don't want to change the UPS, he is so expensive, 680 UAH. Lyul 2518 rubles. What do you advise? Sincerely, Ludmila.

Hello, Lyudmila.
From my analysis on the upgrade of your computer has passed for three months. The situation in the video recorder market has changed noticeably. The GEFORCE 5XX change came the 6xx series - more economical and less noisy. I advise you to pay attention to it. (If there are questions, then better in the theme).

At the account of the UPS:
We already considered the theoritic power consumed by your PC: with new video card (If there is 560 Ti) it will be about 340 watts (at maximum), and a monitor is connected to the UPS.
You can risk, hoping that during the disconnection of electricity (or long deviations from the voltage norm in the network), the computer will not consume not as possible power, and half ... Then the UPS, of course, will endure. Perhaps it will endure short-term load and for greater power.
But I would not recommend in this case to use UPS with a capacity of less than 400-450 watts.
I think it will not be so difficult to sell your used uninterrupted power supply, and thus saving on the purchase of a new one.
- Good day, Seryozha! Thank you very much for the consultation, I will think that it is more profitable to make. We do not have a used machine shops, we will need to look for buyers on the UPS. Without replacing the UPS, I don't want to risk new Vedigart and BP to more powerful. If I do not find the buyer, then better after 1 year 4 months. Sell \u200b\u200bthe systemaker with the UPS and buy a new powerful gaming modern PC. On the video card, the sixth series will definitely draw attention to. With respect Lyudmila

Hello, Sergey. I have a question. Can a systemaker be broken, due to the fact that the UPS is worth it? The laptop began to reboot many times and eventually stopped working. They said Cho exactly from this.

Hello, Tamara.
If there is an incompatibility of the UPS and the computer's power supply unit (there is a mention in the lesson and comments), then with voltage jumps, the computer will really reboot. And such a frequency reboot can lead to the failure of PC.
The same can occur if the UPS is faulty.
Did you say that it was faced within the system unit?

Sergey, good evening you can tell me the PowerCom BNT 800AP USB UPS, connected to it to one socket system, to another through a network filter for UPS LED monitor LG LED E2242C, the system system works, and there is no monitor. What could be the reason?

Yuri, try changing cords with places (the one to which the Systemic is connected, use for the monitor).
It comes across and marriage, it even encountered such that the length of the contacts in the connector is incorrect, as a result, the device did not work.

Hello. While everything is clear. Many thanks for the lesson. Please pay attention to this text. Here one word was repeated twice. (What would be literate like me 🙂

--- In one of the subsequent IT lessons of lessons (but at a higher level preparation), we will look at why this is how and how to avoid this problem. If the question does not tolerate, then contact the comments to this article, I will try to help. ----

word - * lessons *

as for the UPS, you have a good you need. But I have a laptop

Hello Dear Sergey there is such a problem
Neighbors started a large repairs with welding (heating, grid, Waller for a dog, and something else yes plus to all the concrete mixer and other powerful tools and all this in the private sector) we sit on the same line on the second not jump out there. Even worse, "apparently there at all the iron bunker build"
And so from 17-00 to 22-00, I have a disco and at times, it simply fades the light to the "Illych Light bulb" mode measured the voltage during attenuation by 10 seconds shown on the "Chinese Tester" 170-time to 116 volts and As a result of cutting out the computer, although the TV standing next to unchanged (apparently there is another junction on the transformer)
There was an option to use scooped stabilizers (under the TV) but now the voltage is even lower and it does not cope
Today, Pretchuln went to the analysis with the neighbors and remembered that my neighbor (the other) sold the computer and the UPS had it left but he lay down to selling a computer somewhere
Its BNT 400A model (the manufacturer is not specified) it is 210 wat the maximum connection it did not give anything
I am an electrician myself but did not come across the UPS not once
The autopsy has shown that the preloader was convicted at the charging circuit (replaced) but the battery showing 3-5 volts attempted to charge it with a small current from the charger for the car Akb did not give anything after I pulled out and saw a significant bloating and crack (Gel) did not notice, but I started it with the help of a yuloka nutrition (Labotor), but it (block), at startup, littered, but after switching the contour to "Network" stopped
There is an idea to connect to it Akb from a car by 60 amps (they say it will help) but confuses the charge current it 0-75 amps does not destroy the plates of the battery?
Or is it possible to use the UPS as a stabilizer? (This feature is available) and cut the UPS from laboratory BP ???
Replacing the battery immediately disappears because there is no money on the scholarship and eat nothing ...
Big pose Reply to e-mail because I am writing from someone else's computer (I have a disco with differentials)

Stanislav, I sympathize with you. With a similar situation, I came across when I lived in a private house, saved by the consistent inclusion of the autotransformer and the UPS.

I do not have experience with connecting the car battery to the UPS. Of course, the first thing to check is the correspondence of charging currents and the presence of the required voltage. On the forums are often advised to divide charging chains and converter. Come to the conclusion that the battery will not have to be charged, as a result fails.

Mention of UPS + Car Battery Working Systems meet (example: http://forum.oszone.net/post-1323278-26.html), but before an experiment with the connection of the car battery to the UPS, the differences in the specifics of their use should be taken into account: http://www.1000va.ru/actual/?actual_id\u003d10
- Do not be shy. Consult a complaint (to start by phone) in the management of power supply networks and set out your claims. They must come and figure out. In the end, as a consumer, you pay money for electricity that must comply with the requirements of GOST. For the connection of the welding transformer to the lighting network in the evening and on weekends, they must insert wick insert.

Good evening, Seryozha! My imperial linear interactive UPS began to buzz if the plug was in the outlet, but he himself is turned off, hears the hum. Charging battery 96 percent.

Lyudmila, in fact, the buzz at the included in the socket, but the UPS disabled is concerned relatively often. Sometimes this buzz is very poorly audible, sometimes stronger.

If the sound appeared "suddenly," and loud enough, then carry service centerlet them understand what the problem is.

Good day, there was no time and the opportunity to contact you Sergey. At first, I also had no grounding and there were problems with the computer and the UPS, everything was decided! Now it works. The modem failed due to overvoltage, but when, on the advice of one computer, I connected a modem through the IPS-became another picture, the truth had to make a mini outlet for connecting at the UPS itself (it is a pity that all times are not intended for the Modem BP).

Please tell me why the UPS (IPPON is 700 VA) gives short signals and turns off ??? Connected via a network filter. R.S. In the house Al.Kotel.

Olga, the reasons may be several.
1. Perhaps the voltage in the network is over for too long for a valid range (too small or too large);
2. Maybe the battery has developed its service life and it's time to replace it;
3. The problem may be in the load (in what is connected to the UPS);
4. There is a chance that the UPS himself failed.
And these are not all options.

Little information to prompt more accurately, start from checking the first and third paragraph.

In your home, the wiring does not correspond to the power of email. It is necessary to immediately replace the wiring in the house using copper wires in accordance with the maximum power consumed (with a reserve) and soldering places of connections made by a twist. You should also check the quality of the wiring from the meter to the power supply line (on the column). Do not risk.

I read with the pleasure of articles, I can not ask any question, just if something does not clearly reread the article and answers to questions from other users. Thank you.

Hello, Sergey. When I do not work with the computer, I turn off the uninterruptible. I turn on the uninterrupted first (APC Back-UPS 700), then the electrical appliances connected to it. Sometimes the electric power turns on normally. There are cases when when the device is turned on, the uninterrupted starts to squeak, on the connected devices, the light bulbs flashing dimly. Sometimes a squeak and blinking continues for a couple of seconds, then the devices work fine. Sometimes electrical cracks are heard in the instruments in the devices when you have an unpreharika. Just on / off help in all situations. Further everything works fine. The problems described appear only during the primary launch of the uninterruptible. What happens? Inverter with primary startup required time to compensate for lack of power? And the main question: is uninterrupted with electrical appliances? All this is blinking light bulbs and electric crackle worried me.

I am worried about some "network filters" that many have. They look more like simple extension cords. After breaking such a "network filter", you will not find anything like that that can protect the technique. Maximum that can be on this sample is a thermosorrheater and switch. But there is no interference filtering unit at all. I was lucky with my APC. For almost six years, he serves me reliability. But I decided to buy a new one. Sergey, what will you advise me? 🙂

Victor, with filters really not so simple, and most of them are extension cords.
Even the cost does not always talk about the quality of execution, for example:
APC PF8VNT3-RS is one of the most expensive, but there are complaints of assembly quality in recent years.
APC Ph6T3-IT also has controversial solutions that are written in this review.
Energy Elite Most EHV (but not ER) seems to be a good scheme, but there are also complaints.
Good feedback About Defender DFS 805 and Defender DFS-PRO5, but I did not find full-fledged testing.
Cheap filters with minimal permissible parameters Filtration: SVEN Platinum Pro / Sven Platinum / Sven Gold (there are complaints of assembly quality).

If you briefly, I don't know the perfect filter, I do not buy not the cheapest with filtration chains, disassemble and look at the build quality, if there is a need - I correct or leave it as an extension.

For a computer, I consider the UPS mandatory protection.
- Thank you! 🙂 I chose Defender. 😀 And I already have a UPS. APC CS-500. Only he is not working condition. Eashes sound signals and hits. At the same time, the "On Battery" indicator flashes. Even if you disconnect the battery. There is no reaction to the POWER button.

Hello Sergey! I wanted to describe my "uninterrupted". He since 2010. Three years old changed the battery. Model: Back-Ups ES 525. I like it! Although he was expensive at that time, he justifies himself. 3 outlets and one.3 - from interference and battery, and one - only from noise. And this one socket is always working even when I off. uninterrupting button (to this socket I connected a stationary phone-answering machine). There is even a connection with a wire to a computer. If there is any interference on the network, it will be picked up (and if the light is off. It is frowning more often) I open it, and I look at what happened Networks and when. And there is still a fixed telephone protection in it. The cool box is - I like! Thank you !!!

Hello, Sergey. And whether there will be problems if the UPS will be with a network filter (with a fork to connect to the UPS) will be connected 5-6 electrical appliances (monitor 20 ", non-player system, speakers, table lamp, TV 40")?

Hello, Alexander. The main rule is not to exceed the maximum power to which the UPS is calculated (and better, leave the stock of 20-30%). Fold the maximum power consumption of each device (usually indicated from behind on a special sticker), and compare with the maximum permissible powerless power.

Hello, Sergey! I also ask for advice.
I have a laptop on the table, there was Dell since 2008, now ASUS N56V. I rushes. In 2008 I bought a Pover Cube Pro filter, worked fine, always turn on the laptop in the morning and until night, turn off only if I'm leaving.
Recently, he spoiled a toggle switch, he tried to insert him herself
Ships when turned on. Decided to replace, found in Eldorado Pilot GL,
It is more expensive 2 times than Moscow, it seemed to me normally. In the store demanded to believe, paid. At home turned on was afraid - but everything is fine, in the same conditions worked for a week, and yesterday, when turned on-loud cotton, like an explosion, fire and
smoke and turned off the machine guns for the entire apartment. I was afraid to turn on-unexpectedly filter made me a KZ and waited for an electrician.
Today I discovered that in other stores this model is more than more times more expensive. I don't know what to think. I read your article and decided to buy a UPS. I was on the TV Defender RJ45 / RJ11, he has 2 free outlets, but I do not want to load it. By the way, I do not understand it, he needs to change the batteries? He did not bother me, although the filters were saved, the light turned off, the neighbors did a renovation with redevelopment, the noise is incredible, I endured behind the wall, and others came and turned off all automatic machines in the shield, including mine. So my network filters saved me hol-k, TV and laptop. What would you
advised? UPS without any filters? And which? While I have a laptop directly, it is bought, and a month later, the model was removed from production, so I don't know if he has protection against overload, etc.

Hello, Alla!
The filter that has arranged a short circuit - be sure to return under warranty.
Batteries in the UPS eventually have to change, but the service life depends on the quality of the battery and the UPS, there is on the site.
The UPS can be used without a filter, but worse from the filter will not be.
Regarding the recommendations: I have a good experience with the APC UPS, but lately The complaints became more, you need to choose a model according to reviews / reviews (not chase at low price). Good reviews about APC Back-Ups CS 500VA, pay attention to the warranty must be 1-2 years old.

Before you buy a new UPS, you should familiarize yourself with some "internal" aspects of its functioning. And in order for the uninterruptible power supply to serve you as long as possible and investing your funds turned out to be as efficient as possible, try to follow the advice below.

What batteries are used in the UPS

In all UPSs produced by ARS (and other well-known major UPS manufacturers), lead acidic acidic rechargeable batteries, very similar to the most common car batteries. The difference is that, if you already give a similar comparison, then the batteries used by ARS are manufactured by one technology with the most expensive car batteries available today: the electrolyte contained inside is in the gel condition and does not differ during the damage to the case; The battery is sealed, as a result of which it does not require care, does not highlight during the operation of harmful and explosive gases (hydrogen), it can be "conntive" anything, without fear of shed electrolyte.

How durable battery UPS

Despite the fact that in various UPSs it would seem to be the same battery technology, there are vibrations of the operation of the batteries of the UPS of different manufacturers widely. It is very important for users, since the replacement of the batteries is expensive (up to 30% of the initial cost of the UPS). The output of batteries reduces the efficiency of the system, is a source of downtime and excess headaches. The temperature is significantly influenced by the temperature of the battery. The fact is that natural processes that cause aging of the battery are largely dependent on temperature. Detailed test data provided by battery manufacturers show that the battery life of the temperature at a temperature of each 10 ° C is reduced by 10%. This means that the UPS design should provide for the minimum heating of the battery. All UPSs with online topology and hybrid online sources are stronger than the backup or linear interactive (which is why the first fan is required). This is the most important reason why the UPS of the backup and linear interactive types less often need to replace batteries than the UPS with the Online topology.

Is it worth paying attention to the design of the charger when choosing a UPS?

The charger is an important component of the UPS. Conditions for recharging batteries have a significant impact on their durability. The battery life of the UPS battery is maximum in the event that it is continuously recharged from a charger with a constant or "floating" type of voltage. In fact, the life of the rechargeable battery significantly exceeds the period of simple storage. This is because some natural aging processes are suspended by constant recharging. Therefore, you need to recharge the battery, even if the UPS is disabled. In many cases, the UPS is disconnected regularly (if the protected load is disabled, then there is no need to keep both the UPS, since it can work and cause unwanted battery wear). Many of the services offered on sale do not provide an important function of constant recharging.

Does the voltage affect the reliability?

Batteries consist of separate cells, approximately 2 to each. To create a higher voltage battery, individual elements are connected sequentially. In a 12-volt battery - six elements, in 24 volt - 12 elements, etc. When the battery is under continuous recharging, as in the UPS systems, individual elements are recharged simultaneously. By virtue of the inevitable variation of parameters, some elements are selected greater compared to other stakes of the charging voltage. This causes premature aging of such elements. The reliability of the group from sequentially connected elements is determined by the reliability of the least reliable element. Therefore, when one of the elements fails, fails and the battery as a whole. It has been proven that the speed of aging processes is directly related to the number of elements in the battery, in connection with this, the speed of aging increases with increasing the battery voltage. IN best types The UPS applies a smaller number of more powerful elements instead of more elements of less power, thereby achieved increased reliability. Some manufacturers are used by high voltage batteries, which at a given power level makes it possible to reduce the number of wired connections and semiconductors, thus reduced the cost of the UPS. The battery voltage of most typical UPSs with the power of the order of 1QA is 24 ... 96 V. With this level of power in the batteries of the UPS, the company ARS, in particular the Smart-UPS family, voltage does not exceed 24 V. Battery low voltage In the UPS produced by ARS, have a higher service life compared to competing devices. The average life in the ACS batteries is 3-5 years (depending on the temperature regime, the frequency of the discharge / charge cycles), while some manufacturers indicate the service life of only 1 year. During the 10-year term of using the UPS, users of some systems spend on batteries twice as much as the device itself! Although the development of UPS with the use of high-voltage batteries is simpler and costs the manufacturer and cheaper, in this case, hidden expenses are lowered in the form of a shortened service life of the UPS.

Why "pulsing" current reduces battery life

In the perfect embodiment, to increase the time of use, the UPS battery must be kept constantly on "floating" or constant recharging. In such a situation, a completely charged battery selects a small amount of current from a charger, called floating current, or a self-reading current. Despite the recommendations of battery manufacturers, in some battery UPS systems are additionally exposed to a pulsating current. The pulsating currents occur because the inverter generating an alternating current for the load consumes the input constant current. The rectifier located at the UPS entrance always issues a pulsating current. The coefficient remains non-zero even when using the most modern straightening and pulsation suppression schemes. Therefore, the battery included in parallel to the rectifier output has to give some current in those moments when the current at the output of the rectifier decreases, and vice versa, to recharge when the current at the outlet of the rectifier falls. This causes mini-cycles of discharge / charging with a frequency equal to the doubtable operating frequency of the UPS (50 or 60 Hz). These cycles wear the battery, heat it and cause its premature aging.

In the UPS with a battery located in reserve, such as a classic reserve, reserve ferroresonance type, linear interactive, the battery is not exposed to pulsating currents. ONLINE type UPS battery in varying degrees (depending on constructive features), but nevertheless always exposed to their effects. To find out if there are pulsating currents, it is necessary to analyze the topology of the UPS. In the UPS type Online battery is placed between the charger and the inverter, and the pulsating currents will always be. This is a classic, "historically" the earliest type of UPS "Online with a double transformation". If, in the UPS type on-line, the battery is separated from the inverter inverter with a locking diode, a converter or a switch of one or another type, then the pulsating current should not be. Naturally, in these structures, the battery is not always connected to the contour, and therefore the UPS with a similar topology is usually attributed to hybrid.

What in the UPS cannot be reed

Battery - the least reliable element of most well-designed UPS systems. Nevertheless, the UPS architecture can influence the durability of this critical component. If you keep the battery under continuous recharge even when the UPS is turned off (as is done in all UPSs produced by ARS), its operation is increasing. When choosing the UPS, avoid topologies with high battery voltage. UPSs should be watched, in which the battery is exposed to pulsating currents or overheating. Most UPS systems use the same batteries. Nevertheless, constructive differences between the UPS of various systems determine significant differences on the service life of the batteries, and therefore, in the size of operating costs.

Before the first inclusion of the new UPS should be charged batteries

The batteries of the new UPS during transportation and storage in the warehouse, of course, lost most of the "factory" charge. Therefore, if you immediately put the UPS under load, the batteries will not be able to ensure the proper level of power maintenance. Moreover, the self-test procedure automatically launched each time the UPS is turned on (except back-UPS), among other diagnostic operations, checks whether the battery is able to cope with the load. And since the uncharged battery can not cope with the load, the system may not be reporting that the battery is faulty and requires replacement. All you need to do in such a situation - give batteries to charge. Leave the UPS connected to the network for 24 hours. This is the first charging of the batteries, so it requires more time than the usual standard charging, regulated in technical description. UPS itself can be turned off. If you brought the UPS from the cold, let it be warm at room temperature for a few hours.

Connect only the load to UPS, which really requires uninterrupted power supply.

Using the UPS is justified only where the power loss can lead to data loss - in personal computers, servers, concentrators, routers, external modems, strippers, drives, etc. Printers, scanners and certainly lighting lamps do not need UPS. What happens if the printer loses food while printing? A sheet of paper will deteriorate - its value is not comparable to the cost of the UPS. In addition, the printer connected to the uninterruptible nutrition device, when switching to batteries, consumes their energy, taking it from a computer that really needs it. In order to protect the equipment from discharges and interference, the equipment that can be lost as a result of a power failure is enough to use a network filter (for example, APC Surge Arrest) or, with significant voltage fluctuations in the network, a network stabilizer.

If your source often goes to battery power mode, check whether it is configured correctly. It may be that the trigger threshold or sensitivity is too demanding.

Test UPS. Periodically launched a self-test procedure, you will always be sure that your UPS is fully ready for work.

Do not turn off the UPS from the outlet.Turn off the UPS using the button on the front panel, but do not pull it out of the cord from the outlet, unless you leave it for a long time. Even in the off state, the UPS produced by ARS carries out batteries.
