Why utilize the old UPS

Everyone should know that the battery that served his term is a dangerous waste capable of harm to the environment and health of people. Substances included in the UPS (uninterruptible power source) are extremely dangerous and poisonous. Such a device, being on the landfill, highlights toxic components in the soil and water, poisoning everything around. Special danger represents lead. This metal slows down the growth of plants, and also causes serious diseases in animals and people.

Can be used by the UPS, and a few can recycle

That is why it is important to properly dispose of the device. Just throw away the battery on the dump and all the more storing it at home or in the garage will not be enough. You must pass the battery to the reception point so that experienced employees dispose of it for all safety rules.

Advantages of UPS disposal

Passing the old power source to the reception point, you can:

• Safely get rid of unnecessary things;
• Ability to protect the environment;
• Industrial enterprises provide material (all UPS delivered in the end fall on processing plants, where lead and plastic are produced from them, and new devices are manufactured);
• Get a decent reward for each battery sent to secondary processing.

What is UPS

General

UPS (UPS) is a uninterruptible power source that can supply other devices if there is no current in the main power grid.

They are often used in offices where unacceptably unplanned shutdown of computers due to the danger of loss of important data, as well as in everyday life. In addition, uninterruptible power supplies are used in other systems, for example, in server networks. In general, the UPS creates the necessary conditions in order to support the performance of devices in the occurrence of electricity interruptions, it is safe to save data and disable the technique.

The use of the UPS is 3-5 years, after which the device needs to be disposed of in the nearest reception item.

After seven years of use, any UPS is subject to disposal

Device and types of uninterruptible power sources

The UPS usually includes such metals as nickel, iron, antimony, cadmium, copper and lead. The main element of the UPS is the rechargeable battery. It is she who accumulates the necessary energy.

UPS batteries are divided into 3 main groups:

• Lead;
• Nickel-cadmium (alkaline). Used mainly in trains, metro, wagons, elevators;
• Gel. Used in the arrangement of residential autonomous power systems.

About reception locations, who are what they need it

Where to attribute the old UPS

Today you have a few opportunities to hand over an uninterrupted power source. First, contact the auto parts store. Some car masses are engaged in the buyer of the batteries, including the UPS. However, specify in advance whether such a device is being taken.

Secondly, you can pass the battery in a specialized battery or scrap metal reception. At the moment, such organizations are available in each city. This option is much more profitable from the point of view of profit, since at acceptance prices for old UPSs are usually higher than in auto shops.

How to choose a reception point

In order to find a reception point, you can use the search engine of our website:

To view reception points in your city, click the "Select Remains and the City" button, located on the right, and select your city. You can familiarize yourself with the prices, addresses of telephones, and on the basis of this, choose that acceptance that most suits you.

Attempts to revive the UPS far from always lead to the desired result

Rules for receiving UPS

Going to the reception point to hand over an uninterruptible power supply to secondary processing, it is necessary to take into account the following requirements:

• The device must be in an unemployed form and without damage;
• It is advisable to wipe the device outside of dust and dirt;
• When transporting it is necessary to ensure that the UPS does not fall and is damaged.

Preparing IPB to hand: careful packaging will help protect against damage

When passing the battery, you do not need to have any documents with you. The monetary remuneration is paid immediately after the staff of the reception point will examine the UPS, appreciate its model and quality.

Prices for intake of uninterruptible power supply

The cost of serving UPS may vary depending on the city and the reception point, so it is better to call several acceptance in advance and choose the one where the price is highest. On average, a standard uninterrupted power source is received by 53-58 rubles per kilogram.

There is good use for old uninterruptible power sources that are not used because of a small malfunction or because it is unprofitable to replacing the battery. I have such a block, the release of the mid-90s, with a long-notable battery. I will redo it.

In these UPS, hermetic acidic batteries are usually installed, which can be easily removed, twisting 1-2 screws through the door at the bottom. In my case, it turned out that the battery swelled, flowed, covering the compartment with white acid crystals. Therefore, it took to remove the body to remove and clean it.

Electrical modification

We assume that the electronics is proper, then the alteration is as follows:

1. Turn off the network cable. Sut off the network plug and solder the connector for 12V. Although this cord will work, it is better to use another, with a large wire diameter. Low voltage and permanent current mean high ampening values, therefore, need thicker wires.

2. Insert a new cable into a regular hole and strengthen the stopper.
3. Disconnect the wires from the circuit breaker. One wire of the new cable is soldered to the rear contact of the circuit breaker.
4. We connect the wires of the battery to the new input. One wire connect with a 2nd contact of the circuit breaker. Other - with the second wire of the new cable. Polarity should be observed! Usually on cars Red wires are "+", and black "-".
5. We modify the mechanical switch on the front panel so that the unit works immediately when connecting the connector (you can also apply a two-position switch). Often they have 3 positions. "Shared" is usually in the middle, the value of 2 others determine the tester when the switch is pressed. Connect a common with the contact Test / Network on.

Testing

Check the performance, correct voltage and frequency values.

To configure them in these blocks, there are usually trimming resistors.

Caution! There is a high voltage in 220V!

Using

We collect the case. The new inverter can be used for laptop, etc. Do not connect devices to it, where there are engines. For the UPS, it is recommended that the load is not more than 75% of the output power. If you did not use a fairly thick wire and fork, I would recommend to reduce this figure to 50-60%.

And I also want to celebrate one moment, if you decide to buy a new car, that is, an excellent car dealership in Moscow, where prices will pleasantly surprise. Hurry up, promotions and loans, discounts and responsive staff will help you with a choice.

UPS (Uninterruptible Power Supply) - a device that feeds a specific power system in cases if there is no energy in the main power network. Such batteries are involved in various equipment and techniques. Most often, they can be seen in offices, stationary power systems and server rooms. In fact, the UPS creates the minimum necessary conditions for maintaining the performance of devices in the event of interruptions with electricity.

Useful use of the battery for uninterruptible power sources is 3-5 years, after which the device is replaced with a new one. It is prohibited to drop batteries to the dump, since in the decomposition process they begin to distinguish toxic substances into the ground and air. Help the environment and well to make it possible, if you pass the battery of our company. We carry out the use of UPS batteries at the highest prices in Moscow and Moscow region. The list of services provided and the current scrapbook can be found in the relevant sections of the site.

Our prices for receiving batteries

Areas of use of batteries from UPS

The main component of the uninterruptible power supply is the battery. She is able to accumulate, keep and spend energy in emergency cases. Their composition includes various non-ferrous metals. This is usually lead, iron and copper, but nickel, cadmium and antimony use in a number of devices. It turns out that the Akb in the specialized reception point is beneficial.

All existing types of batteries from the UPS are divided into 3 main groups:

• Lead. Used for autonomous and spare systems with standard and alternative energy sources.
• Nickel-cadmium (alkaline). Batteries of this type are used in various highly specialized techniques and machines: trains, metro, wagons, elevators.
• Gel. The average operational period of such batteries reaches 10 years, due to the implementation of the redistribution of hydrogen and oxygen. Instruments are characterized by increased safety, stable with powerful discharges, explosion-resistant and have a large coverage of operating temperatures. These factors led to the ubiquitous use of gel batteries in the arrangement of residential autonomous power systems.

In addition to the battery from the UPS, our company can be handed over other types of batteries: automobile, traction, in ebonite buildings.

Conditions for receiving batteries

To pass the batteries as a scrap, the following conditions must be observed:

• We produce batteries without visible damage in unbearable form. When estimating the value of the scrap, the weight of non-metallic inserts is not taken into account.
• Lead and nickel-cadmium devices must have a minimum blockage.
• Alkaline batteries must be empty - without acid.

Prepare batteries for delivery is not difficult. If any difficulties occur, it is enough to call us for qualified advice.

Why utilize old acb?

Substances contained in batteries from the UPS cause irreparable harm to nature. Such devices have a second class of danger, but at the same time dozens of batteries come to the landers. Toxic components accumulate in the ground, then seep into the water and evaporate into the air. Animals and plants become a peddler of severe diseases, the risk of contamination of the population increases.

Our company provides you with the opportunity to deliberately treat the problem of environmental pollution. Everyone has the right to attribute unnecessary batteries into our specialized reception points and get good money for it.

Establishment of spent batteries

Our company buys batteries from the UPS at the best prices in Moscow and the district. In addition, we provide a number of related services that allow you to quickly and comfortably get rid of the old scrap. We do:

• removal of scrap metal;
• dismantling old metal structures;
• disassembling cars and engines.

Sale of batteries - another our direction of activity, so if you want to sell old and immediately buy a new battery, then just call us.

In order to solve whether it is necessary at all the uninterrupted or not, it's a pretty think about what problems with power supply May occur when working on a computer:

All current uninterruptants for computers are divided into three groups. Uninterrupted rooms from different groups differ among themselves with some properties, the presence or absence of some functions, etc.

Something else that you need to remember is that the disappointment is that your computer is immediately turned off when the power is turned off even for a few seconds. When it comes to buying the right uninterruptible power supply for your data center, the size matters.

• You forgot to specify email address.
• This email address is not displayed.
• You exceeded the maximum limit of characters.
• Specify the corporate email address.

And it became that "more better" is usually perceived as something of granted.

How to choose a uninterruptible computer

After the user learned about the existence of such devices and met them closer, he may want to acquire himself uninterrupted. But in order to buy, you need to first carefully weigh the pros and cons" And whether this device really needs to be solved. After a positive response, it should be understood in uninterrupted books, not to get into the unpleasant situation or in vain to spend more money than was originally assumed.

First, we need to understand the terminology. The power factor is defined as the ratio of "real power" and "apparent power", but this is not a technical article, so everything we are going to say on this issue. But this is a watt figure, which is important for today's data centers, so we can allow this mystery.

We need to understand that this thing, called the power coefficient, is rarely 0, with the exception of incandescent lamps, heaters and toasters. It is usually less than 0 and never larger, so watts are usually smaller than Volt-amps. With the best coefficients of power, it is even smaller, so we said that the error does not matter if you do not have a large number of hardware.

The power of the uninterrupted (BA) must be equated to the plug-in load (W) and the resulting value is divided by 0.7.

It is very important to note that sellers can confuse VA and W, which can provoke a non-compliance in the calculations of the buyer and the recommendations of the seller. If we assume that the buyer will go to the seller who made such a common mistake, he will have to be content with the source of uninterrupted nutrition, the power of which will be significantly less than the expected approximately 1.4 times, which subsequently cause problems, not to mention the spoiled mood.

Communal enterprises regularly summarize the reasons for any electricity outages in their newsletter or regular reports. The reasons vary from everything that is listed above, to animals penetrating into transformers and other components. Regardless of whether the power break occurs for a few seconds or a few days, it is necessary to continue. And they must do it continuously and consistently.

Causes may vary, but interruptions in work are concerned about how projects will be completed on time and in the budget. Each business and households need lights, heat, equipment and other essential items, and, of course, flourish. No power, injury, loss, damage and reduced income become unnecessary.

conclusions

Uninterruptible power supplies are devices that can help users in their work on personal computers. In addition to power maintenance, some uninterrupted models perform control function For voltage and warning breakdowns. It is possible to state the fact that uninterruptants can extend the operation of a personal computer and to protect it against the adverse effects of power problems.

Now imagine another script when the power source takes place. In case of a long-term disconnection, it allows a lot of time to convert into an alternative power source. Imagine that your building is a building that continues to hum, despite the circumstances, and people inside him are tranquility, not chaos.

What is uninterrupted power supply systems?

And with the full system, you can remove the "power output" from your list of problems. The technology continues to improve as the importance of maintaining power for basic systems and operations is becoming increasingly more important. Many people do not understand how much the world based on data has changed the general needs for energy, since the Internet and large data as a whole continue to stimulate demand for cleaner and reliable electricity. Energy jumps, spikes or failures cause fluctuations and disorders that may adversely affect your equipment and your data, so the systems provide a clean, serial and continuous stream of power that protects against these effects.

No one is insured against the unpleasant consequences of various failures in the power grid. This can happen with each of the users of personal computers. But problems can be eliminated by the presence of a uninterruptible, which perform security feature and relieve troubles.

It is not so difficult to choose a uninterruptible, but it is definitely impossible to call this process. The fact is that all the characteristics of uninterruptible power sources are not so easy to fit in the head, and not everyone can figure out. But in principle, if you remember the main important functions of uninterrupted, you can choose a device that is suitable for a specific personal computer.

Generally speaking, the uninterrupted nutrition system can be anything from a small black box that sits somewhere near your table and protects your personal computer from megaton, megawatny models that can manage a large business. Protection against electricity interruptions ensure sufficient power during short-term breaks and "travel time" for conversion to backup power. Turn on the backup power source for long-term discs, such as generators. Specify the quality of the power as it arrives in the building, office and equipment. . Usually you will find battery-based systems in small operations, such as a home computer or office, as well as the configuration of the flywheel in large systems used to power large objects.

Acquisition of a uninterrupted person for his personal computer will allow the user to avoid problems that are most often associated with failures in power networks. If the problem occurs, the uninterrupted can be switched to power from batteries, which will extend the work of the computer. This will allow the user avoid possible problems With data damage or with their loss.

Manufacturers of uninterruptants for a computer are enough, but to break the head and choose the device of a certain manufacturer of the presented assortment is not worth it. This does not justify the spent forces and nerve. There is no need to carry out a deep comparative analysis, since, in fact, all models are uninterrupted, which have similar characteristics worth the same and work approximately the same.

Uninterrupted rooms - indispensable assistants of users who perform a huge amount of work and whose activities are inextricably linked with the computer. You can hope for the illusory quality of power networks and their uninterruptedness, but it is better to act practically and once again progress.

In our electrical networks, unfortunately, there are sometimes interruptions, and in such situations it is necessary to protect expensive equipment from overloads. In addition, in such cases it is important to keep information on the computer from irrevocable loss. For this, there are sources of uninterrupted nutrition, abbreviated - UPS. Today we will talk about how to choose a good UPS for a computer, and that is important in this device. The market presents a huge number of similar equipment, and if you decide to read this article, it means that you cannot decide on the final option. Good power supplies for a computer today can be made through the most different technologies. Depending on what purpose you use a computer, and you need to choose this equipment.

Types

It is pre-talking about the basic types of uninterruptible power sources for a computer, which in the market there are three options.

Reserve

Reserve UPSs are most primitive in terms of design. They are distinguished by the fact that they react to a 10 ms power supply network. At this point, switching to the battery. Such budget dietary supplies for a computer are suitable for private home use only if you do not have any problems with power interruptions. There is no voltage stabilizer, which means that with any intermittent device will switch to the battery, which addicted to the duration of its service.

Linear interactive

Linear interactive power supplies for a computer solve this problem. In the event of a voltage jumps in the network, they automatically adjust to the existing current level. This largely increases the life of the device. By the ratio of price-quality power for a computer of this type are considered the best.

Online

The best, but most expensive are the online UPS. They react to the voltage drop in the network instantly. The principle of operation of this type is to double the transformation of incoming electricity. First, the rectifier converts alternating voltage to constant. Then the inverter back converts it into a variable. But unlike the backup and interactive computer and other devices constantly get energy from online, and electricity with a clean sinusoid, leveling voltage. This device constantly responds to changing the current, and transmits this information to the computer.

Main settings

Here we will deal with the main criteria of devices that will help determine the choice. You can also understand which parameters affect the cost of equipment.

Power

Power is considered one of the main characteristics of any UPS for a computer. If the indicator of the total power of the computer will exceed the power of the inexpensive device for the computer, then this may lead to the output of the latter, or constant reboots. Be sure to pay attention to this parameter before purchasing. You need to know what power consumes your personal computer and all peripheral devices connected to it. To determine this indicator for uninterruptible power sources, it is worth multiplying the existing total value by 1.4. It is this power supply that is necessary for this device.

Battery life

This parameter for most budget UPSs for a computer is approximately the same. Autonomous time is approximately 5-8 minutes. This is often enough to save all applications and complete the operating system in the right mode. For those who use their PC resources to the maximum, this may not be enough. Fortunately, some manufacturers offer models whose battery life increases to 15-20 minutes. Of course, you can independently increase the battery capacity, and make it better. For this, manufacturers produce additional batteries on the market. By their required time characteristics, they can be achieved.

Software

Many modern best UPSs for the computer are supplied with special programs that allow you to save the device statistics files. If a person is not at home, the equipment will independently save all operating information on the hard disk. This is a very useful option, for which you need to pay attention to when buying.

Number of connectors

The inexpensive UPS for the computer is often supplied exclusively with a computer connector. In fact, there can be a wide variety of peripheral devices. It is necessary to calculate how many houses you have such devices, and on the basis of this already draw conclusions about the purchase of a particular equipment. There should also be a socket with protection against voltage jumps. Do not forget about the protection of the telephone line. If this is not done, then the modem connected to it, during interruptions with electricity, can soon fail soon.

Noise level

It is also worth paying attention to the purchase of the power supply. Some inexpensive UPSs for the computer work loud enough, which can cause various troubles; For example, people may have headaches. Try not to install the power supply directly next to the bed. It is better to even separate it from his bedroom partition.

Indication and controls

Modern best UPSs for the computer are capable of not only to feed sound signals in the event of switching modes of operation, but also to issue information using LEDs. It is very convenient if there is an opportunity to observe visually for the state of the block. Some models are able to inform the user about the need to replace the battery. Relatively recently, equipment appeared on the market, which is equipped with liquid crystal displays. It may be displayed up to 20 different states of the block. In addition, some models are complemented by controls. They allow you to adjust the power supply under a specific network operation mode.

Ability to replace the battery

Today, you can find uninterruptible power sources for a computer that implies the replacement of the battery during operation. The average battery life is approximately 5 years. During this time, he completely exhausts its resources. There are models that intend to replace the battery after its expiration date. Pay attention to them before buying, because it is better to buy a battery than a new UPS, and such devices will save your money in the future.

Manufacturers

Today, you can find various both expensive and inexpensive UPS for a computer on the market. There are many producers like this. The best are the companies - APC, FSP, IPPON.

Conclusion

Sources of uninterrupted nutrition have long settled in our homes along with computers. And the benefit of these devices is difficult to overestimate, because they protect computer techniques from failures in the electrical network, and in this regard, our nerves will shove in. A good UPS will reliably protect your electronic devices from overload. Thanks to him when the electricity is disconnected, your computer will work for a while, feeding from the battery of the equipment. This will allow you to safely save all the data and turn off the computer in normal mode. In conclusion, it is still recommended to do not particularly save on the price of the device, and to buy at least linear interactive so that it works in automatic mode, and better - online UPS. That's all that I would like to say how to choose a good UPS for a computer that will last long. Take care of your e-equipment and do not spare money for a good device.

Many PC users have the old IPS spent on their best. Their cause of disability is the failure of batteries. Since the replacement for new batteries is unprofitable, and sometimes it is simply impossible due to the lack of analogues, these devices simply roll out without affairs or are thrown into the garbage.

But you can give the second life of the UPS, making it a very useful device from it - an inverter that converts 12 in the onboard network of the car into a 220 V for some instruments. Moreover, the factory version of the inverter will cost considerable money, and so you will save money, and make the necessary thing from the rubble.

So, the first thing you need to do is remove old, dried batteries. They are simply dismantled enough by removing the bottom cover and turning off the power wires. If traces of dried electrolyte remain, clean the housing from oxidation crystals.

Such an operation will ensure the elimination of further intend to the acid, and will also greatly facilitate the weight of the device.

Changing the connection scheme

According to the design, uninterrupted rooms are different, but the principle of operation is the same - transform the voltage of 12 V 220 V. That is, each model has a platter with an electronic voltage converter. I need it. But there is one condition, it should be workers.

Since the devices that will connect to this device have a standard fork on 220 V, it is necessary on a side or rear panel, set a conventional household outlet for hidden wiring. To her, and solder the wires from the converter 220 V, which were previously approached to a special three-rod fork on the rear panel of the UPS.

In the first and second case, the wires are soldered to the fact that they went to the battery of the UPS. It is very important to comply with the polarity of the connection. Red wire is a plus, and black is minus.

Like in the network of cars and in the UPS, these colors should coincide. Best of all, of course, check the polarity by a multimeter to make sure.

This connection scheme provides for the instantage of the device when it is connected. If you want to make an inclusion through a toggle switch or automatic, then simply in the wire, which comes from the car's battery, tear the "plus" and attach one wire to the entrance, and the other to the output of the machine fixed on the UPS housing. Thus, the power of the inverter is broken when it is necessary.

Subtleties in work

It should be understood that such a device will not give a greater power. Usually. It is no more than 150 W, but this is quite enough to connect a small TV, laptop and other low-speed technology.

Why the car battery does not charge from the charger
