Title: Dual Tracking power supply regulator wanted!
Post by: BobbyK on March 29, 2013, 01:57:08 am

I was wondering if anyone had any schematics lying around or could point me to something useful. What I have in mind is a fully regulated, and current limited dual tracking supply. No need for fancy control scheme - pots will do. The problem has been finding something that can handle +- 70V (i.e. 0-70Volts on each output) and at least 1 Amp on each output. I'd appreciate any schematics that could be modified to suit my needs. Thanks in advance.

What on earth do you need ±70V at 1A for?

Power amplifiers!

Oh, and I have already built a suitable power supply (~800VA) that I could use, but I really would like to be able to limit the power to my devices, and also to ramp up power slowly before putting the final touches on this amp. The parts alone have cost me upwards of 600 USD for the amp boards - don't want to damage them :(. And regulation would be awesome too, to test future amps,....hence the need for a current limiting dual tracking power supply :)
