I’ve had two phase perfects. I bought them because I understood they provided cleaner power and I had invested a lot of money on my equipment and realized an electrical problem was something I

In my previous 1PH shop, i used a phase perfect converter, and it was superb.

Eric thanks for your response. What makes the phase perfect the better choice vs a rotary converter? Price is a consideration as I’ll have lots of other shop and house projects to do so if I can

Good luck with your move! I bought a Phase Perfect and it has worked very well. The specs are good, and when Felder learned I was installing a Phase Perfect, they didn;t bother having me send in the

After 4 years in my current commercial ship rental with three phase, I’m taking the plunge and buying a house with a 1k square foot detached garage. Closing is July 22, move will take place in

Only complaint, so far, on the door opener, control box supplied with no knock outs. Does not make any sense. It is not possible to use it w/o hooking it up to power, motors and sensors

It is amusing to see solutions without a clear problem statement. Imran

David, your reasoning is why I want the OP to check the output voltages to verify they are within spec for the machine. Motors might run on lower voltage but they tend to get hot, especially the

Dave’s approach never worked for me - even by switching the 24V transformer tap inside the machines to boost the output to the control circuits and moving the PP manufactured leg around. I’m glad

Now that the machine is up and running, I'd check the voltages between the three legs and see what you have ( T1-T2, T2-T3, T1-T3 ) . Compare to what is on the motor plate to see if you are within

Terrence, Glad you are up and running. Since we really want to learn from each other I am not exactly sure what was your issue. One possibility is that the input to the PP was incorrect as described

All and especially Dave Kumm: Thanks for the input. I checked the PP documentation and determined the manufactured leg, traced it, swapped wires to keep the T3 from the machine controls (trial &

fwiw, 208v is not "low voltage" in the sense of some defect.? ? It's just a different electrical distribution system.? It's very common in certain industries, for example, IT data centers. As

David: Thanks for the tip, I called PP and they will not supply but agreed with the fix in concept. Will source one here locally. Terry

Dave: I checked the 3 prongs at the plug, they read 120, 120, and 208…I have no idea how to move the 208 from the control circuit? The Dual spins the right way. Terry

I had the same problem when I moved from Virginia (240 supply) to California industrial park (208 supply). The solution was a buck/boost transformer between the panel and the Phase Perfect. Phase

I do not know industrial setups. It would definitely be worthwhile to measure all 3 outputs of the PP, phase to phase. My assumption was that PP is receiving 208VAC phase to phase, if such a thing

The code is flashed by a LED. Short pause when counting long pause end of digit. If the issue is low secondary voltages then the solution would be to change transformer. You are within +/-10% input

Check the output voltages on the PP. The 208v only applies to a three phase application with three legs measuring 120v to ground vs 240 delta where the third leg measures 208v. the two incoming legs
