About the Product

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.
