Cedar auto 4a what is the output voltage. How to use the charger cedar. Safety Requirements

The Kedr AUTO 4A charger is designed to charge and restore the performance of acid lead 12-volt batteries, partially lost as a result of sulfation and oxidation of the electrodes, as well as their training by conducting charge-discharge cycles in order to increase the resource, service life and shelf life.

The Kedr AUTO 4A device provides automatic shutdown at the end of the charge in the "AUTOMATIC" mode. The device is equipped with a pointer indicator (ammeter) and a light indicator, which: when the "AUTOMATIC" mode is switched on, does not glow; at the end of the charge in the "AUTOMATIC" mode - flashes; when the "CYCLE" mode is turned on, it glows evenly.

The KEDR-AUTO device provides an accelerated charge mode for a completely discharged (up to 10 V) battery with a compromise value of the initial current equal to 3 - 4 A. At the same time, after 1 - 2 hours (depending on the degree of battery discharge and the mains voltage), the value of the charging current decreases to a value of about 2 A and continues to decrease towards the end of the charge to 1 A or less. This mode eliminates significant battery heating during charging and reduces the charge time for a fully discharged battery to 3 - 6 hours.

Before using the device, it is necessary to study the rules for the care and operation of batteries.

Open the cover on the back of the charger and remove the cords. Set the toggle switch for turning on the automation to the "CHARGE" position.
The “CONTINUOUS-CYCLIC” charge mode toggle switch allows you to select the battery charge modes.
If it is necessary to charge the battery, switch the charge mode toggle switch to the "CONTINUOUS" position.
If it is necessary to form or desulfate the plates, if the battery capacity decreases, switch the charge mode selector switch to "CYCLIC". Connect the load to the battery terminals (light bulb 12V 6 W).
Connect, observing the polarity, the cord with the clamps to the battery.
The electronic protection of the Kedr-M device against short circuit and incorrect polarity connection is designed in such a way that the charging current appears at the output only if a voltage source (battery) with a voltage of at least 10V is connected to the output terminals.
The lamp connected to the charger terminals will not light up, as it is not a source of voltage.

Working in battery charging mode.

Switching between the operating modes of the device "INTERRUPTED-CYCLIC" and "CHARGING-RECHARGE" can be done in the process of charging the battery without disconnecting it from the mains.
Connect the plug of the 220 V power cord, and the process of charging the battery begins, as evidenced by the ammeter readings.
The charge current of a completely discharged battery at the beginning of the charge can be 4 A or more, then the current will decrease during the charging process.
When the battery charge is reached, the charger automatically turns off, as evidenced by the glow of the "END OF CHARGE" LED
Switch the toggle switch for turning on the automation in the "RECHARGE" mode and continue charging the battery. The battery is considered fully charged if the density of the electrolyte does not change during the charging process for two hours.
In the cyclic charging mode, after every 45 seconds of charging, the battery is discharged for 15 seconds through the load (light bulb) connected to the battery.
In the "CYCLIC" or "RECHARGE" position, the automation is switched off.

Possible malfunctions and methods for their elimination

Despite the fact that the charger is simple and reliable in operation, in practice there are cases when consumers, due to improper use, cannot obtain the required charging current and mistakenly consider this to be a malfunction of the charger. These errors are summarized in the table.

Regular maintenance is required to prolong the life of your starter car battery. One of the mandatory items is to maintain a normal charge level. This is especially true for winter operation, because due to the large number of powerful consumers and severe frosts, the standard car voltage relay is not able to fully charge the battery.

Maintenance

Device overview

The charger is made in a plastic case small size(185x130x90 mm). The low power of the device led to its low weight.

On the front panel are:

• Pointer ammeter to control the charge current;
• LED indicator of operating mode;
• Mode switch "Cycle - Automatic".

A power cord and wires with terminals for connecting the battery come out from the rear panel of the device.

Technical characteristics of the Kedr Auto 4a device

This charger provides a charge current of up to 4 A. This is enough to maintain the capacity of not completely discharged batteries. Other specifications:

WET batteries are standard wet lead acid batteries. Do not attempt to charge an AGM, EFB or GEL battery with this charger.

The set of memory includes instructions for the rules of use, which details the procedure for operation and possible malfunctions with the order of their elimination.

Features of the device and for which batteries it is suitable

The automatic charger is designed to charge lead-acid batteries with a capacity of 40 to 75 Ah.

Important! The larger the capacity of the battery, the longer it will take to charge it. Moreover, many manufacturers recommend setting the charge current equal to 1/10 of its capacity. Therefore, this device is not recommended for regular charging of high-capacity batteries with a high degree discharge.

The device has built-in protection against incorrect switching on - polarity reversal. Output voltage and charge current are absent in such cases:

• Incorrectly connected battery;
• High degree of discharge (voltage at the battery terminals is less than 10 V);
• No battery.

Kedr Auto 4a has two modes of operation - "automatic" and "cycle". Each of the operating modes uses its own charging algorithm.

The operation indicator light has the following modes:

• Redeemed - "Automatic" mode;
• Blinking - in the "Automatic" mode, the charge is over;
• Continuous glow - the "Cycle" mode is on.

Machine

This mode is the main one and is designed to charge batteries without user intervention. The logic of operation is such that when a discharged battery is connected, the device starts to produce a maximum current, which decreases as the charging process proceeds. When the voltage reaches 13.2 V at the battery terminals, the charge automatically stops.

Important! The initial current depends on the degree of discharge of the battery, but does not exceed 4A in the most extreme case.

Cycle

The mode is designed to restore batteries with signs of sulfation. In the cyclic mode, the charge alternates with a short-term discharge with a low current, which contributes to the dissolution of large sulfate crystals in the active mass of the plates.

How to charge the battery using Kedr Auto 4a

The use of an automatic device simplifies battery maintenance as much as possible and allows it to be done regularly without a significant investment of time.

Procedure:

• Connect the battery to the output terminals of the device;
• Connect the device to the mains;
• Select the required operating mode by pressing the button on the front panel.

Important! In the case of desulfation (“Cycle” mode), a load must be connected in parallel to the output terminals - a 12 V 6 W car lamp, through which a training discharge of the battery will be performed.

Using a more powerful lamp will increase the discharge current, resulting in a longer charging time. A weak load, on the contrary, will not give the desired effect.

During the charging process, it is necessary to control the density of the electrolyte. The absence of density growth with an undercharged battery indicates that desulfation is necessary.
