bap8guy | Adjustable Bi-Polar Power Supply, 0-24v 1A @bap8guy | Uploaded February 2022 | Updated October 2024, 22 hours ago.
Utilizing a low cost regulator board from China, I decided to cobble together a usable bench supply for use with my op amps. For the regulator to function as a usable adjustable power supply requires finding a good cabinet, switching the small trim pots to actual front panel potentiometers, installing an on/off switch, several terminal binding posts, and the construction of a transformer driven filtered power supply! All of this was done and the unit functioned...for awhile.
The regulator board claims to be good to 1A, however there is not sufficient cooling for the regulators on the board. As a result, the positive regulator failed during testing and required replacement. I also have de-rated the supply to .5A until additional cooling can be installed.
The video is a review of what has been done.
