Phase Technologies Phase Perfect PT-355 Phase Converter
Large motors run more efficiently and last longer on three phase (3Ø) power than on single a.k.a. split phase power. We’re way the heck out at the end of the power line and it would cost $85,000 to bring in 3Ø power for our butcher shop. Not happening.
The solution is to either run the machinery inefficiently on single phase or to get a three phase converter. Since the equipment is rather expensive I don’t want to shorten its life, or make it noisier than necessary which also happens with 1Ø power.
Three phase converters come in several varieties. The rotary phase converters have been around for a long time but are in efficient and not as cheap as they appear since you have to essentially buy twice as much power as the rating of the equipment.
Digital phase converters are newer and more expensive. Doing the math I discovered that the digital phase converter’s increased efficiency meant that it will pay for the higher cost vs the cheap rotary phase converter within in one to two years. After that it starts saving us money every month. I like that.
Digital phase converters also produce cleaner power which is better for the motors and they’re quieter, although not silent. Interestingly, their buzz is high enough pitched that not everyone can hear it. Both Will and I could quite clearly when I powered our new unit up. It works. It’s not going in the office. Good thing we built a dry mechanical room for it!
Now for the tricky part. The phase converter arrived and we took it indoors. I went to open it but couldn’t figure out how. Now I’m very good at puzzles so this was unusual. And there were no instructions on how to open it. After a bit of unproductive pondering I called the company and spoke with tech support. Turns out you have to use an unusually large allen wrench inside a hidden spot within the door bumper. And where were the instructions for how to do this? Inside the machine, where else! You can see the manual there on the far side after I got it open. Cute.
Well, it works. We got it hooked up to our single phase also known as “split phase” power which really should be called two phase power in my book and out the other side of the phase converter flowed three phase power. Nice!

I to Will: Do you have a vise?
Will: No, but I would like to learn to smoke.
