Gregory Member Jan 12, 2004 #1 I am building a DC power supply I am using a transformer 240V Primary to 25 volts on the secondary at 5 Amp's Could some one supply me with a circuit digram to bild this power supply with Variable voltage & variable Current

Roff Well-Known Member Jan 12, 2004 #2 Go to **broken link removed** and look at "Bench Top Power Supply", parts 1-4. Not exactly what you're looking for, but pretty close.

W Wuey New Member Jan 12, 2004 #3 I built this 1.5V-24V 5A regulated power supply a few months ago: http://home.iprimus.com.au/peterwu/Electronics/PS24V5A/Power Supply1.html The voltage regulator is LM338. I suggest you use a bigger case for maximum cooling efficiency.
