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

1. the function of undervoltage indicator:If voltage is large enough,the indicator is on.when the voltage is lower than 2.7V,the indicator is off and you should charge the battery,or it might be damaged.
2. when output voltage is as high as 6V,you’b better connect the input power supply first and connect the load second.

Aplications

• 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.
• make your power supply stable:when your power supply is not stable,you can use this module to make it.
