Charger cedar 10a. Review of chargers for the car battery series "Cedar. Safety Requirements

Comments (17):

if you put a zener diode at 8.5V, will it be okay? will it not affect the operation and characteristics of the device in any way?

# 2 root June 14 2017

Victor, here are the parameters of the KS175Zh, which is installed in the circuit:

The minimum stabilization voltage is 7.1 V;
Nominal stabilization voltage - 7.5 V;
The maximum stabilization voltage is 7.9 V;
The stabilization current of the zener diode is 4 mA.

As you can see, the zener diode has a certain spread in the stabilization voltage: 7.1-7.9 V. It is used in the circuit to power logic chips of the K176 series.
Most likely, replacing the KS175Zh with a zener diode with a voltage of 8.5V will not affect the operation of the charger in any way.

Got me in the repair KEDR AUTO 12V, I don’t know for a year. For all CEDARS I will not speak, only on the example of this instance. The printed circuit board and wiring diagram correspond to Fig. 10. Schematic diagram - fully corresponds to Fig. 7. Scheme Fig. 3 contains obvious errors, the connection of the DD4 - K176TM2 microcircuit is incorrectly shown. There, even for the DD4.2 part, the microcircuit legs are incorrectly numbered. In my copy, it was this microcircuit that failed, I had to sort it out. As shown in the diagram in Fig. 3 - the node on the DD4 microcircuit cannot work correctly. It would be better to remove it .... the circuit in Fig. 3.

# 11 root January 09 2019

Alex, thanks for your comments. Errors corrected. We checked the numbering of the pins of all microcircuits in Figure 3 - for the DD4.2 element, 12 were swapped with 13 and 10 with 11.

All health! They gave me a 12v cedar in a faulty condition, the problem is in a trance. TPP3-2-220-50k did not find anything in the current network (it consists of 1 primary 1-2, and two secondary 5-6, and 4-3, the resistance of the primary and secondary and output voltages is very necessary.

# 13 Pavel February 04 2019

Hello, What do R5 and R9 regulate? How can you limit the voltage to 14.8V?

# 14 Dmitry February 06 2019

Good day everyone! One person has already asked about the KU 202g alternative. I'm not very good at radio and electrical equipment. One of the thyristors is out of order. In the store, when buying, "master sellers" assured that KU 202g and Ku 202zh were interchangeable (at that time, KU 202g were not on sale). Yes, of course, after installing the KU 202zh, the device works, but the automatic shutdown does not work when the battery is already fully charged.
You have to constantly watch so that there is no recharge and the plates in the battery do not crumble.
Maybe there is still an alternative EXACTLY KU 202g?

# 15 root February 06 2019

Thyristors KU202G and KU202ZH are identical in characteristics with the exception of the parameter "Constant voltage in the closed state", where it is equal to 50V and 10V, respectively.

The circuit is low-voltage and this parameter may not be so critical here, perhaps some other details are out of order. It is necessary to check if all the transistors and diodes are in good working order, to study the operation of the device and check the microcircuits.

On the board there is a trimmer resistor R5 "End of charge" (diagram in Figure 7), it may have been twisted without understanding and the device is not configured to turn off the charge when a certain voltage level on the batteries is reached.

# 16 ALEX February 11 2019

Hello. For the memory, the cedar stopped working due to the breakage of diodes in the circuit of the control electrodes of the thyristors.
Replaced diodes and thyristors. Charging went only in a cyclic mode. When the automatic mode was turned on, the LED turned off, the ammeter showed a current of 2 A and turned off after a couple of seconds. Slightly stirred R5, the charge went a little longer. The tester on a battery / 40A / showed the power on at 13.4 and off at 14.4 everything would good, but there was no fixed shutdown. Zu turns on with the specified parameters and turns off until you disconnect it from the network. Please advise how it should be. Thank you in advance.

# 17 Alex March 14 2019

the charge occurs in a cyclic mode. those. the needle of the ammeter deviates by 1 A and then drops again to 0 A. and so on with a frequency of about 50-60 Hz.

In the arsenal of every motorist must have a car. Operation of a vehicle without this device can be significantly complicated. A car charger can be most useful during the winter months when the battery needs to be charged more frequently. When the battery is completely discharged, you will have to "light up" the car, which is not always convenient, and in some cases may require additional expenses due to contacting the service station. It is much easier to charge the battery at home. One of the most popular brands of car chargers is "Kedr" - devices of this brand are bought by many vehicle owners.

Model range of chargers: "Kedr-M"

Charging "Kedr-Auto" is intended for recharging car batteries. Such equipment is mainly used to restore the performance of batteries, which have lost it due to the reactions of sulfation and oxidation of electrodes. In addition, the service life can also be increased with the help of the Kedr-Auto Mini charger by training the charge-discharge cycle.

Device functions

Automatic termination of battery charging.
Cyclic charge-discharge mode, the action of which is aimed at restoring the capacity of the battery as a result of the sulfation reaction of the plates.
Protection system against short circuits and incorrectly connected clamps.
Provided recharge mode, which allows you to collect the full capacity of the battery.

Preparation for work

On the back of the charger there is a special compartment in which cords with clips and a network cable are hidden.

The voltage of the Kedr-Auto 4A charger can harm human health or cause death. The device must be turned off before starting restoration and repair work and changing the fuse. It is strictly forbidden to install self-made fuses and block the ventilation openings of the case. In addition, the battery must not be charged in the vicinity of heaters.

Before starting work, the cords with terminals are removed from the rear compartment of the device. The first lever of the device is switched to charging mode, the second - to cyclic or continuous mode.

How to use Kedr-Auto 4A?

Continuous mode is used when full battery charging is required.

The cyclic mode is used when forming or desulfating electrodes. In this mode, a 6-watt 12-volt light bulb is connected to the terminals.

Then, the terminals are connected to the current leads observing the polarity.

The Kedr charger has a protection mode against incorrect connection and short circuits. The instructions for the Kedr-Auto 4A charger indicate that its operation is possible only if a rechargeable battery with a minimum voltage of 10 volts is connected to the terminals. When you try to restore the charge of a completely discharged battery, the device will turn on the protection mode.

Switching operating modes can be carried out without disconnecting the charger from the network. According to reviews on "Kedr-Auto", the current strength at the beginning of the charging process is 4 A, followed by a gradual decrease. The charger is automatically turned off after the battery is fully charged, which is indicated by a special LED. After that, you can put the charger into recharge mode.

Charging the battery in a cyclic mode lasts 45 seconds, after which a special light is turned on. This mode does not have an automatic shutdown, so it is advisable to control the whole process.

"Kedr-Auto 4A" and "Kedr-Auto 12V"

Both models are used for battery recovery, battery charging and charge-discharge training cycles.

On the rear wall of the devices there are power wires and connections to the battery. There is no special compartment for placing wires in these models. The instructions for the Kedr-Auto 4A and Kedr-Auto 12V chargers describe in detail the rules of operation and the procedure for use.

The charger "Kedr-Auto 12V" has the following technical characteristics:

The rating of the rechargeable batteries charged with the device is 12 V.
Supply voltage - 220 V.
Maximum power consumption - 85 A.
Current strength - up to 4 A.

Charger "Kedr-Auto 10"

This model is an improved version of the previous charger - "Kedr-Auto 4A", which was created in 2008. The device is used to charge a 12 volt battery.

Distinctive features of "Kedr-Auto 10"

Pre-start mode, the current strength in which is 10 amperes.
The rated current is 4 amperes.
The power consumed by the device is 250 watts.
The charger allows with a maximum rating of 12 volts.
The charger operates on a standard 220 V network.

Battery charging time varies depending on its capacity and degree of discharge. A microprocessor built into the charger controls charging and prestarting mode. All modes are switched on and the device is activated after the device is switched to automatic mode. First, an increased charge current is supplied, after which its strength is reduced to the nominal, which significantly speeds up the battery charging process.

Operation process "Kedr-Auto 4A"

The instructions for the Kedr-Auto 4A charger describe in detail the process of using the device and charging the battery. It is impossible to disable the charger, since the protection system protects it from damage even if the terminals were initially incorrectly connected.

Auto mode

Restoring the full charge of the battery is carried out as follows:

The terminals of the charger are connected with the correct polarity.
The charging mode "Automatic" is switched on.
The plug is connected to the 220 V network.
The charging process will be interrupted by the device automatically after reaching the maximum charge level, which will be notified by the flashing indicator.

Cyclic mode

In a cycle, the battery is charged to full capacity as follows:

A 12-volt car light bulb is connected to the battery terminals. It is advisable to select a light bulb with a power of 6 watts.
Connect the terminals with correct polarity.
The corresponding button starts the "Cycle" mode. In this mode, the charge indicator is constantly on.
The charger is connected to the power supply. This mode does not imply automatic shutdown, respectively, the discharge and charge cycle can be repeated indefinitely. For this reason, the user must independently monitor the charging of the battery.

Before the direct process of charging the battery, the plugs are unscrewed from the cans. After charging or recovery, the terminals are disconnected only after the charger is disconnected from the 220 V network.

ZU "Cedar": user reviews

Most of the reviews left for Cedar chargers are positive. The most popular model of the device is Kedr-Auto 4A. Somewhat less often you can find reviews for the Kedr-Auto 10 model.

Among the advantages of the memory car enthusiasts include simplicity and ease of operation, the low price for "Kedr-Auto" (about 1500-2500 rubles) and a long service life. Users often note that the charger can last ten or more years without any complaints. Cycling is one of the main benefits for many users, as it allows desulfation and recovery of old batteries. Car enthusiasts often note that with the help of this mode it was possible to restore the working capacity of the batteries, which had been completely discharged for a long time. Of course, it is impossible to completely restore the battery capacity, but you can achieve a positive effect.

However, you can also encounter negative reviews. Some owners of Kedr-Auto chargers note that the battery is not charged in automatic mode. If the capacity of the battery exceeds 60 Ah, then its charging takes a very long time due to the 4 ampere limit. The same rechargeable batteries with a capacity exceeding 70 Ah are not fully charged. Users also noted that Kedr-Auto chargers do not charge those batteries, the charge of which has dropped below 10 volts.

Despite all the negative reviews and shortcomings, Kedr-Auto chargers are among the best and most popular in the automotive market. The devices allow you to quickly charge batteries, are distinguished by a long service life and wide functionality, and are significantly ahead of their competitors from other brands.

The service life of the battery - the source of the vehicle's life - is 5 to 7 years. It all depends on the operating conditions. However, it is possible to increase the battery life if it is periodically recharged and special trainings are carried out. For these purposes, the Kedr charger was developed - one of the best in the entire Russian automotive market.

The operation of any storage battery is based on anode-cathodic reactions that occur between lead cells and a sulfuric acid solution. As a result of the reduction of lead dioxide at the cathode, we get an electric current. However, over time, the course of the reactions weakens. It is then that it is necessary to connect "rectifiers" that restore the original elements.

Series of chargers "Kedr"

The main purpose of the series of domestic devices "Kedr" is to charge the storage battery and restore its performance, lost due to the formation of lead sulfates and oxidation of electrodes. In addition, the "Kedr" charger can be used to "train" the battery in order to improve its technical characteristics and extend its service life.

Externally, the devices of the series are a black plastic parallelepiped of a rather large mass. The control panel is located on the front side. The device has a cable for connecting to the AC mains, two clamps that are connected directly to the battery terminals. The device is configured for recharging in automatic mode.

The series of devices includes pre-starting devices that are used to start the engine of a car with a highly discharged battery ("Kedr-mini"). Also in the assortment there are universal units that perform both functions (charger "Kedr-auto-10").

Control Panel

Before starting the device, you must familiarize yourself with the rules of its operation. Failure to follow this simple rule can cause electric shock or even death.

The most important thing is to study the control panel of the device before connecting it to the battery. In the overwhelming majority of cases, it includes:

Switch for control of automatic modes "Charge / Dose".
Fuse holder, in other words - fuse slot.
Toggle switch of automatic modes "Continuous / Cyclic".
Ammeter and indicator of full battery charge in the form of LED.

There is a small compartment in the rear wall of the device, which contains the cords needed to connect the "Cedar" charger to the mains and the battery.

Differences between devices and other chargers

The family of devices "Kedr" fell in love with domestic motorists for their ease of use.

The device recharges or restores the battery's performance thanks to the automatic functions built into its control board:

Cyclic work - provides a partial restoration of the redox capabilities of the electrodes during the sulfation of elements.
Recharging the battery - brings the constant charge to full capacity.
Battery shutdown mode after fully charged.

Also, the device is equipped with automatic protection against short circuits as a result of accidental contact of the output clamps or incorrect connection of the battery. When triggered, the protection system simply stops supplying electric current, thereby protecting both the Cedar charger itself and the battery.

Before charging

Before you start charging, you need to make sure that your battery needs recharging and is working properly. To do this, you need to measure the voltage at the terminals. In winter, the maximum allowable discharge level is no more than 25% of the nominal value, and in summer - no more than 50%. If the voltmeter shows values below, then the battery needs charging.

Standard car batteries have a nominal voltage of 12 volts. Only in this case "Cedar" - a charger (instructions below) - can charge the battery. Also read the battery data sheet to make sure that this is the case. Remember that the voltage in the charger must be higher than the battery voltage to charge. Otherwise, nothing will work.

User manual

The instruction says that to charge the battery, you must do the following:

Remove the cords from the cavity on the back wall, carefully stretch them on the floor, make sure that the clips do not touch.
Connect the device to an alternating current source of 220 volts.
Switch the toggle switches to the "Charge" and "Continuous" positions.
Observing the polarity, connect the clamps to the battery terminals.

Restoration of performance

A decrease in battery capacity occurs as a result of partial sulfation of the plates - the formation of sulfates on the electrodes. In this case, it is possible to increase the efficiency and increase the durability of the battery. This requires:

Connect the device clamps to the terminals.
Move the toggle switch to the "Cyclic" position.
Connect a 12V or 6V bulb to the battery.

The restoration of operability occurs according to the following scheme: the charger "Kedr" for 45 seconds charges the battery, and then turns off, and the lamp comes into operation, which discharges the battery within 15 seconds. Such cyclic charging / discharging increases the battery life and performance.

Possesses a high degree of protection against incorrect connection, overload and short circuit of the terminals;
The model is equipped with the most modern transformers manufactured by the leading enterprise of the Russian Federation;
There is a pre-start mode - afterburner mode (the battery is charged at a current strength of up to 10A), after which it automatically switches to nominal charging with a current strength of 5A;
After the end of the process of charging the battery with a current of 4 A, the system will automatically switch the device to recharge mode at a current of 0.5 A. Thus, the battery is fully charged and is not allowed to be recharged;
There is a possibility of desulfation of the battery in a cyclic charging mode;
The warranty period is exactly one year from the date of sale;
In automatic charge mode, the rated current is 4 A;
With correct operation and observance of storage rules, the service life is at least five years;
The weight of the device does not exceed 0.6 kilograms.
Charging the battery and restoring its performance lost due to the formation of lead sulfates and oxidation of the electrodes.

Important information for the car enthusiast who wants his battery to last a long time.

Let's take a look at the chemistry of the process

When the battery is discharged, a white coating is deposited on the plates from the electrolyte. This is a normal process (sulfation). And if you start charging the battery in a timely manner, then it is restored. But if we allowed a deep discharge, the plaque crystallizes, and charging will not provide cleaning of the battery plates, it will sharply decrease.

That is why it is necessary to recharge the battery almost daily. This means cleaning the plates and keeping the battery in perfect, working condition, extending its trouble-free life for a long time. The Kedr-auto charger allows the car enthusiast to easily cope with this task.

2. The device provides automatic transition to the low-current recharging mode upon completion of charging in the "AUTOMATIC" mode.
