Default Current Ratings.

Hi Mahmoud.


Just one question after this long discussion,

Is this power supply stable for long time operation?

have you loaded it with fixed loads for 1 hour? to draw 6 amps? 4 amps?

what is the current rating for it?

It can deliver +/-50V 6 Amp continues?
Thanks...

Hi,

This is a fascinating design and I built it using my own layout. I would like to share it with others DIYers. I modified it for different voltages.

The design works perfect with around 500W constant load with little rise in mosfet temperature.
Controller board is same for both designs
