Input reverse polarity protection.

Built in output short protection function.

Built in thermal shut dowen function.

LED digital voltmeter tube,the accuracy is adjustable function,can be aimed at your multimeter adjustable accurate.

Press the right key to let the dispaly show the input or output voltage.when the right".

OUT" led light,it shows output,the left "in" led show input.

Note: Some customers report: "The module can not be adjusted, the output voltage is always equal to the input voltage." When you encounter this problem, please counterclockwise rotation of the potentiometer 10 laps or more, then you can adjust the output voltage. Because the factory default output voltage is 20V.
