DC 12V Intelligent Charger Module Power Supply Controller Board Battery Automatic Charging Protection Board

Description When the battery voltage falls to the range of 10 5 11 5V low voltage adjustable then the protection board will automatically charge again when the power off voltage is in the range of 14 4 14 8V the protection board will stop charging high voltage adjustable During the charging process the red lamp is on when it is fully charged red lamp is off When the relay disconnects 220V input port will end charging so as to save the energy This board is assembled with a dedicated voltage control IC and a special automotive relay It is small in size large in current accurate and stable in turn off voltage considerate in protection complete in functions and reliable in performance which can really give you peace of mind Parameter Working voltage DC 11 5 14 5V the highest cannot exceed 15V otherwise the chip will burndestroy Relay closed charging voltage 11 5VRelay disconnect protection voltage 14 5VVoltage error 0 1 VVoltage detection method DC voltmeterCharging type 12V storage batteryPotentiometer adjustment VR2 start voltage VR1 full power protection voltageSize 50 x 32 x18mmSupport charger power AC 220V 10A 2000W does not support iron core transformer chargingWhen first starts charging test please discharge the storage battery If you connect the battery and the red lamp is off immediately and the relay disconnects please contact us and do not adjust the potentiometer in person or it won t restore to normal status Function 1 this b
