This article is to explain a simple variable DC power supply circuit to explain. The circuit is simple but effective. For your more thorough grasp of this principle, we suggest that you can know more about some of the important components of the circuit, for example: LM 317. This power is based on the  LM317  variable regulator. Enter the regulator requires about 28 volts DC, and it outputs a DC voltage from 1.25 vdc 25 volts DC. Adjust the output voltage just 5 k ohm pot. Regulators will provide 1.5 amps of current.
