Diy Bench Power Supply Circuit. It is capable to provide up to 1.5a, from 0 to 25v. A power supply can be considered truly complete only if it has facilities for a continuously variable voltage, short, current, and over load protection and the output is perfectly regulated and stabilized.
Normally a standard lm317 ic power supply is designed to work with inputs not exceeding over 40v , which implies that you cannot enjoy the features of this wonderful linear device for. Lm338's data sheet has several very helpful application notes and circuits. Power supply is based around a lm723 voltage regulator chip and has current limiting.
This is a high quality bench power supply with adjustable output voltage from 0 to 30v and adjustable output current from few miliamperes to 4 amperes.
After many years of employing this ugly and clumsy bench power supply, i decided it was time to build something better, smaller and nice looking. It will keep a stable voltage when it has any load.
