Indicator Light :
Constant current indicator (red LED)
Charging indicator(light red)
Charged full (Light Blue)

Applications:
High-power LED constant current driver
Lithium battery charger (including ferroelectric),4V, 6V, 12V, 14V, 24V battery charger,Nickel cadmium, nickel metal hydride battery pack charger
Solar panels and wind driven generator.

Battery Use:
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)
