300W Voltage Step Down

300W 40V 20A DC DC Voltage Step Down Power Supply Module

Voltage and Current Adjustable Step Down Power High Efficiency Low Noise

The pots on the product are multi-turn (30 turns).  To see the voltage drop, you need to turn it about 20 turns counterclockwise.

Attention, this product only steps down voltage. It cannot be used in the voltage step up operation.

     300W voltage step down module. There is a 1V voltage drop between input and output. Thanks to the terminal blocks at the input and output, connections can be made easily. When the device is running, the led next to the input terminal blocks is on. 

     There are 2 adjustment pots next to the output terminal block. Voltage and current adjustment pots. These pots are multi-turn (they can turn 20-30 turns.). To be able to see the effect, you must turn the pots a lot. You can use it with a constant current output by limiting the output current to a certain value.

     The switch next to the input terminal block is used to turn the product on and off.
