DIY 0-30V Regulated Power Supply
Introduction
So over the weekend I saw a commercial 0-30V 3A regulated power supply with digital output, current & voltage control. The only drawback was it costs RM499 which is well over my budged. So I decided why not build my own from whatever i could scrap and save some money. Firstly I didn’t need current control and i needed something within 1A. Searching the interweb turned out many designs but they were all complex and most didn’t come with eagle schematics, then I remembered that last year i purchased a schematic book from Jalan Pasar which had a schematic for a 0-30V AC/DC Regulated Power Supply able to supply up to 1A, the schematic looked easy enough plus the parts were relatively inexpensive.
