Make sure of the voltage and current of the battery you need to charge
Adjust the constant voltage potentiometer to make the output voltage same to the charge voltage
Potentiometer Adjustment Direction: Clockwise (increase), counterclockwise (decrease)
Use the multimeter in 10A current scale to measure output short-circuit current, and adjust the current potentiometer to make sure the output current to the expected charging current value
The charge current of transfer lamp is default 0.1 times of the charging current (constant current value)
Connected to the battery and try to charging (for previous 5 steps, module input terminal is connected to power source, output load is NOT connected to batteries).
LED Constant Current Driver Use:
Make sure operating current and Max operating Voltage of the LED you need to drive.
Adjust the constant voltage potentiometer to make sure the output Voltage is up to LED Max operating Voltage.
Use the multimeter in 10A current scale to measure output short-circuit current, and adjust the current potentiometer. To make sure the output current to the expected LED operating current.
