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 burn
destroy.
Relay closed charging voltage: 11.5V
Relay disconnect protection voltage14.5V
Voltage error: 0.1 V
Voltage detection method: DC voltmeter
Charging type: 12V storage battery
Potentiometer adjustment: VR2 start voltage, VR1 full power protection voltage
Size: 50 x 32 x18mm
Support charger power: AC 220V, 10A, 2000W, does not support iron core transformer charging

When 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 board can allow 2KW transformer, and the battery can detect high level or low level so as to achieve auto charging management.

Function 2: this board has reverse connection protection; when it does not connect battery, there is no output; whether the battery clips in the output port touch or not, users can plug it safely. When the polarity of the battery connects reversely, there is no output, this is an very practical function. Output short circuit and auto closed are also practical protection. No matter the charger is in what kind of status, once output is short circuit, then the charger will automatically close the output.

Wiring instructions:

The relay is used to control the on and off of the charger. You only need to connect any 220V line into the COM terminal of the relay, (output) the OFF terminal to the charger. The charger must use a full-bridge rectifier output, and the DC output voltage is about 13.8 to 14.4 V is enough. One end of the board is connected to the battery detection voltage, and one end is connected to a voltmeter to monitor the voltage. The potentiometer adjusts the start and protection voltage.

Adjust 1: VR1 when the battery voltage is charged to 14.4-14.8V, then the relay will disconnect, and the charging process will end (blocking voltage setting: if clockwise adjust, the blocking voltage will be low; if counter clockwise adjust, the blocking voltage will be high)

Adjust 2: VR2 when the battery voltage falls to the range of 10.5-11.5V, the relay will operate and start to charge. (starting voltage setting: if clockwise adjust, the starting voltage will be low; if counter clockwise adjust, the starting voltage will be high)

Note:

It is recommended not to adjust the potentiometer, otherwise it is easy to damage the module.Only fine-tuning potentiometer, can not be a substantial adjustment

1 x Intelligent Charger Module
