5A DC-DC Step Down Voltage Regulator (Buck Converter) Constant Voltage, Constant Current

This step down voltage regulator uses high frequency switching to make a very efficient DC-DC converter. It can take an input of 6V to 38V and lower it to between 1.2V and 36V at up to 5A (output). The voltage is set with one potentiometer and the constant current can be set with the other from 0.1A to 5A.

Voltage in : 6V - 38VDC

Voltage out : 1.2V- 36VDC

Constant Current Range : 100mA - 5A

Maximum Output Current : 5A

Dimensions : 52mm x 26mm
