Absolutely, but the price goes up tremendously with power. I am now pricing an 80kW system and it seems to be 70k$ (about half of it is the batteries for 30 min uptime so some of the price could be cut). Come to think about it, the rule of thumb seems to be 1k$ per 1kW I suppose a CNC system could use a simple power conditioner for the power feed to the motors and the UPS for the electronics/controller, but that does not guarantee against power surge getting into the power stage and flowing back into the controls. ------------------------------------------------------------------------------ Increase Visibility of Your 3D Game App & Earn a Chance To Win $500!
