A switching power supply is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently.
A variable power supply is one that includes some means for the user to easily adjust the output voltage. Adjustment is most often accomplished with a potentiometer, but may also be done with an analog control voltage, a digital input, an autotransformer, etc.
The adjustable 3~12V power supply makes it suitable for different charging devices and different situations.
Durable, easy to operate, a built-in LED shows the voltage in real-time, helping you to control the charging condition in real-time.
This power supply is suitable for speed control of DC motor, light dimmer, etc.
Its efficient power adaptation provides super low interference and stable voltage help achieve highly efficient power adaptation.
