Hey Guys, We've found ourselves in somewhat of a bind. We've got a PCB router in house which is powered from 3-phase 208V. Its a very, very long story, but its going to be 10wks till our utility supplies 3-phase power. Currently we have 240V single phase power, so I've looked into a phase converter but we still need to bring the voltage down to 208V. The other option we've been trying is to use a generator. Turns out that when the 5hp vacuum motor fires up, the generator doesn't respond quickly enough to counteract the effect, so we suck the voltage (and frequency) through the floor. This of course causes the motor controllers to complain. We've got a 20kW generator already (for a ~4kW load), so I don't think a bigger generator will fix the problem. Is there another way around this with a generator? (Ie, could we try to run the controllers from a UPS or will we kill the UPS?) If we were to run a 3-phase motor load continuously while we run the router, would it tend to buffer the effect? Power systems is well out of my league, so any comments you have would be welcome.
