12V automatic charging power control board, automatic charging, automatic power off anti-overcharge protection device
Product Description: When the battery voltage drops to about 11.5V (low voltage adjustable setting) when the protection board will automatically charge, when the voltage reaches about 14.5V protection board power failure to stop charging. To achieve automatic charging, automatic power off anti-overcharge function.
The board uses a dedicated voltage control IC and automotive special relay assembly, small size, current, power off accurate and stable, well thoughtful, full-featured, reliable performance, really can let you rest assured.
Operating voltage: DC 11.5-14.5v, the highest can not exceed 15v, otherwise the chip will burn.
Relay closed charging voltage: 11.5v
Relay off protection voltage 14.5v
Voltage error: 0.1v
Voltage detection mode: DC voltmeter
Charging type: 12v battery battery
Potentiometer regulation: VR2 start voltage, VR1 full protection voltage
Product Size: 33 * 50mm
Support charger power: AC 220v, 10A, 2000 watts, does not support the core of the transformer charger
Status display: red light when charging, full of red light off, the relay disconnect the 220V input end of the charge, which play an energy saving effect.
Function 1: This board uses genuine pine music relay control, support the charger transformer maximum power 2KW, the battery through the protection board to detect high and low level to carry out automatic management charge.
Function 2: This board has a reverse protection function, not connected to the battery No output: regardless of whether the output of the battery clip is interrupted, can be assured plug. Battery polarity reversed no output: This is a very practical function, even if the blind is not a problem. Output short circuit automatically shut down: This is also a very practical protection, no matter what the state of the charger, as long as the output short circuit, the charger will automatically turn off the output, so as to effectively protect the charger will not burn out due to short circuit.
