DC power supply for CNC?
I got two 10,000 uF capacitors from digikey, 100v max, 18000 hours
life. When charging the caps niitially, would the diodes be stressed?
Oversize the diodes; large rectifier bridges are dirt cheap. I've buit
many supplies for AMC and Copley servo amps with just a transformer,
rectifier bridge and cap and never had a problem. Oh, and don't forget
a bleed resistor for the cap.
Ah, come on. You're spoiling Iggy's fun. I got zapped by an electrolytic cap
once. Gets your attention, and then you learn all about bleed resistors and
never forget them.
