ProductDescription : Specifications:
Size of PCB: 50 x 32 x 18 mm
Default Value:
Low Voltage: 10.5 V  
Shutoff Voltage: 14.8 V (adjustable, might be different)
Wiring Method: Please wire according to instruction. Do not change wiring.

Instruction:
Connect any wire of 220 V with the COM port of relay, and connect charger with OFF port.
The charger must be full bridge rectified output.
The DC output voltage can be between 13.8 and 14.8 V.
Charging test for the first time: battery voltage should be about 10 V.
Function 1: Current cannot be larger than 10 A.
Function 2: The board has reverse connect function. There is no output if no battery is connected. No output if the polarity of battery is wrong.
Output short circuit automatically shut down: It is a practical . As long as the output short circuit, the charger will automatically shut down output, so the charger from burning.
