Re: [CAD_CAM_EDM_DRO] Power Supply Circuit

Great!

I need to build up a snubber for my supply. Is yours some kind of
zener/driver/power transistor?

I am running at reduced speed and acceleration due to a too small power
supply.
I recently got 3000w transformers that will give me about 60 vac. That will
give about
85 vdc which is about right for a 90vdc max amp. The combination of line
overvoltage
(common here) and servo regeneration charging the cap could cause amp
overvoltage
shutdown often so a snubber would be a good thing for me.
