User guide

How to use

First give the right input voltage,and then monitor the output voltage with a multimeter and regulate the potentiometer to change the output voltage until you get the right output.(usually output increase clockwise,decrease counterclockwise)The output voltage can be regulated continously.

Little notes

When temperature outside is over 40 degrees centigrade,please lower using power or strenthen heatsinking.


  • mobile power supply:when you are on business trip or in tourism,you can prepare such a mobile power supply so that you can charge the battery of your mp3 or mobilephone with some other batteries.
  • voltage adjusting:when you design needs different voltages,it will be a good choice to use this module.
  • stablize your power supply:when your power supply is not stable,you can use this module to make it.
