RE: [CAD_CAM_EDM_DRO] electrical help wanted

I do presume you are using a diode / bridge rec etc to get the DC you need.

100 Volt caps would be ideal for this setup and as you rightly say the more
uf the better !

No need for the resistor setup you speak of as the amps should compensate
for small ripple etc

Designing a PS for Gecko drivers.
The transformer gives out 50-0-50 what size capacitor should I use ?
ie 50v rating or 100v and the bigger the capacitance the better or what?
I remember in the OLD days that one put a capacitor across the output
then a resistor inline and another capacitor across the output. I
suspect this was great for the ripple effect but perhaps the Gecko
dont care.
