Instead of using batteries, which have a limited lifetime, a variable dc power supply can be used which is implemented in this project. This is the best variable power supply circuit diagram. With these costing you only $25 and having short circuit protection, thermal protection, overload protection and … This bench power supply design uses a pass transistor which works like a variable resistor, regulated by a zener diode. With the device powered down, adjust the output voltage control, p1, to get zero volts, the current control pot, p2, for optimum current (maximum resistance), and pt to zero resistance. Prices today for a lab power supply well exceed $180. But it turns out a obsolete computer power supply is perfect for the job instead. The majority of the power supply designs thus far incorporate a linear series stabilizer.

It's also very easy to build, making it an ideal beginner's project. For smaller voltages, we normally use batteries as a reliable source. Yescom 110v ac 30v 10a dc power supply. Best of all this design does not require you to mess around with any high. Power supply is based around a lm723 voltage regulator chip and has current limiting.
Dc power supply variable 30v 10a. It will keep a stable voltage when it has any load. I have used several power sources for my projects over the years. Or incorporating a single chip for the active functions. Aside from the atx power supply itself, we will need a few additional components to build our bench supply. The design needs to have a suitable current meter. The three things you list would be my preferences for a kit. In this instructable, i will show you, how to make a variable lab bench power supply with a limited budget.it is a great diy project for beginners as well as any one interested in electronics.
Here is what i used to build my supply (not including the materials i used for an enclosure).
No voltage/current display good, so i can add my own. Or incorporating a single chip for the active functions. Hello, friends in this video we will make a variable power supply. I consider this to be just below the dmm in essential test equipment. With the device powered down, adjust the output voltage control, p1, to get zero volts, the current control pot, p2, for optimum current (maximum resistance), and pt to zero resistance. The question arises, though, as to what type of supply and what features should be incorporated so as to make it as universal as possible. For this project i am using an old atx power supply which has been salvaged from an dell optiplex desktop. I recently upgraded it, you can watch my 12v & 19v ups video.
