Function Description:
1. The module has IN/OUT, ON/OFF two buttons:IN/OUT button switches input voltage and output voltage display, long press to switch output current output power display;ON/OFF button control output ON or OFF, long press can set default output state is ON or OFF when powered next time.
2. CC is current setting potentiometer, clockwise rotation can increase setting current, when the load current reaches setting current, it enters constant current state, and CC constant current indicator light (red) lights up;CV voltage setting potentiometer on the right can be rotated clockwise to increase output voltage.ON indicator light shows output state, which lights up when output voltage, otherwise lights off.

Matters needing attention:
1. Module input IN- must not be short-circuited with output OUT-, otherwise the constant current function will fail.
2. Please make sure that the power of the power supply is always greater than the power required by the output load!
3. If the module wants to output at full load, the input voltage must be above 8V.
4.The module has input under-voltage protection function, the default is about 4.7V
