RE: [CAD_CAM_EDM_DRO] Re: Power supply voltage.

I think that Tim was really trying to warn you that, as the AC input voltage
fluctuates, the DC power supply output fluctuates as well. If the Geckos are
rated at 80 volts, I'm sure there's some derating of the transistor's
rating. However, we don't know how much Mariss has derated things to come up
with his value. In addition, I understand that back voltages generated by
the motor (yes, the motor can behave like a generator) may impress much
higher voltages than the 80 volt input supply max.

Lots of things to consider. Personally, I'd stick with no more than 80
volts, if that's the spec.
