Thread: RAM EDM running off a Phase Perfect Phase Converter?

Does anyone have any first hand experience of running a CNC RAM EDM off a Phase Perfect phase converter? I just want to make sure there are no unforeseen issues I don't know about in respect to these machines and the Phase Perfect. I ask because as an example, a digital multimeter doesn't always work correctly checking voltages on my 3 phase equipment run off the Phase Perfect. I have to use an analog meter so I don't get bogus readings. However the Phase Perfect generates power doesn't work with how the digital multimeter checks. This is not really related, but it is a type of unforeseen thing. I want to make sure there is nothing similar in respect to CNC RAM EDMs running off a Phase Perfect.

I don't have the specific 1st hand experience you are asking for, but I can tell you the output of a PP unit is as good, or better, than utility power in terms of voltage balance across phases, waveform shape, etc.

I've been using a Phase Perfect for several years now.

It runs everything just fine.

A Matsuura MC 1000V VMC, Cincinnati Milacron 208U chucking lathe, my Aratron 300 sinker EDM, and the manual mill.
I can run up to three units at a time, so long as the load on each is light.
I would never try starting more than one at once, due to the initial surge load .

The one issue I had was that my building is actually wired 208 Wye, so I had to move a couple of wires in the unit to get correct output.
Phase Perfect tech was very helpful despite my not buying the unit from them, I bought it used.

When I finally get a better building with three phase power, I expect to recover my purchase price passing it on to the next user.

my Cnc Fadal VMC, and my old non cnc Raycon r20 both run off my PP. at the same time.

I suspect your PP is not right if your digtal meter does not work correctly on it. Maybe you have bad capacitors?

get someone to oscilloscope the output, under load and not. should be quite clean looking.
