Re: Plasma voltage servo : Mariss?

Hi Mariss-
Further up the thread I mentioned that I built the circuit, but it
only steps inside the deadband and we need it to step outside the
deadband towards the deadband. I believe we are looking at 115-130
volt D.C. and from what I've read it looks like 1/2 volt is a pretty
standard dead band. Due to the variances in every system ( plasma
brand and steps per inch of movement ) I think it makes sense to
build the board with sockets for easy component changes or maybe
variable pots.
Thanks!
Todd
