A few months ago an electric spike fried the spindle drive of one of my CNC lathes. I'm looking for protection from such incidences in the future.
I was told by a man in the business that a type that is basically a transformer will even out the spikes and limit damage, for from $500 to $2500 per machine (Of which I'd only equip the 3 most expensive).
But talking with a retired engineer who was an engineer in a large plant years ago he said a single point between incoming power and the main breaker that uses back to back zener diodes would limit the peak power at whatever value is set and anything over that value would be dumped to ground, plus would be much cheaper and cover the whole shop.
Do any of you know about such a setup and whether it would meet the need?
Thanks for any info in advance,
