12v Battery Charger Controller
Non-returnable
BD 7.500
12V Battery Charging Controller Module Protection Board Automatic Charging Stop
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 protection 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 protection. As long as the output short circuit, the charger will automatically shut down output, so protect the charger from burning.
Adjustment:
VR1 relay disconnected to shutoff when battery charging voltage to 14.4 V. (shutoff voltage setting: clockwise lower, counterclockwise higher)
VR2 relay connected and began to charge when battery voltage is 10.5 V(low voltage setting: clockwise lower, counterclockwise higher)
Package includes:
1 x Charging Control Board
