CONSTANT CURRENT BUCK CONVERTER

Constant Current Buck Converter
This Constant Current Buck Converter works as a high-power constant current driver module and as a buck converter module with over-current protection.

How to set current limits:

Adjust voltage potentiometer to make output voltage reach the voltage value which you want.
Use 10A multimeter to measure short-circuit output current (directly connect two meters to output interface), while regulating the current potentiometer so that the output current reaches a predetermined over-current protection value. (For example, the meter displays the current value of 4A, then you can use the module to a maximum current of 4A)
LED indicator light:

Red light is on in constant current status and off in constant voltage status.
Blue light is on when charging and off when full charge.
Green light is on when full-charge.
