This is Constant Voltage and Current Output module. Use this module to step down an input voltage between 7-35V to an output voltage of 1.2-35V . An onboard potentiometer can be used to set the desired output voltage by the user. The module can also regulate the maximum output current to be supplied between 0.2A to 9A. The required output current can also be set using an onboard potentiomter by the user.
These features make this module a great powersupply for electronic projects, battery chargers, and led drivers. Please use external heatsink and fan if you are drawing high power and temperature for the module increases beyond 65 degree Celsius.
