Description:
This module has a delayed disconnection and can automatically restore output function. That is, the module will disconnect the output after the battery is under voltage for 3 to 5 seconds, thus avoiding the misoperation due to the voltage fluctuation of the battery when the large current load starts. When the battery's voltage picks up to a charged voltage, the battery automatically turns on the load and disconnected the charger.
Voltage values of undervoltage and voltage-filled voltages can be set by adjusting potentiometers. Setting these two values requires 12V power and multimeter. You shouldn’t adjust yourself without these two tools. The default undervoltage value is about 10.5V to 11.5 V, and the voltage of the recovery output (full voltage) is 14.4v to 14.8v (other voltage can be inferred from this).

Examples Explain:
Example 1:
If the load is the motor, the voltage of the battery will fluctuate at startup, the delay time can be used, and the time-delay module can be used, and the delay of 3 to 5 seconds is enough to restore the battery voltage.
Example 2:
When the car started, the light in the car would flash.This is because the current is larger at startup, the voltage of the battery fluctuates, and the time-delay module can be used, and the delay of 3 to 5 seconds is enough to restore the battery voltage.

Features:
1>. With the indicator light, the protection function is straightforward.
2>. Strong commonality;
3>. The maximum is 30A current of the board that is suitable for most battery.30A refers to the load current (load not exceeding 30A) of the relay contact, not the current (capacity) of the battery.

Wiring Instructions:

 



Turn on the battery, the green indicator on board light up.
When the battery voltage is normal (load output), the red indicator on the board is on and the load is connected;When the battery is under voltage (below 10.5 v-11v), the board will automatically disconnect the battery and load, connect the battery and charger, and the red indicator will be out. When the battery is full, the load will be automatically switched on and the charge will be disconnected.
Note:
The battery interface and the charging port are without reversed electrodes protection. Please distinguish the positive and negative poles before wiring.


Force Boot Up Instruction:
Connect the load first,then the battery and finally the charger.
The first time to connect the modules. If the voltage of the battery does not reach the voltage charged, the load may not be connected. If you want to force the boot, you can short-circuit the following two points with a pair of metal tweezers to force the boot up.


Potentiometer Adjustment:


1>. Adjust the under-voltage voltage load off voltage:
Clockwise adjustment the voltage step up and counterclockwise step down.
Turning half lap clockwise is up 0.4V(Do not exceed two laps adjustment.), while turning half lap counterclockwise is down 0.4V(Do not exceed two laps adjustment.).
2>. Adjust Over-voltage voltage charging off voltage:
Clockwise adjustment the voltage step down and counterclockwise step up.
Turning half lap clockwise is up 0.5V(Do not exceed three laps adjustment.), while turning half lap counterclockwise is down 0.5V(Do not exceed one lap adjustment.).
Note:
When you adjust the potentiometer, please remember the number of laps.
