DPS Single-Phase to 3-Phase Converter, My-PS-7.5 Model Must Be Only Used on 5HP(3.7kW) 15 Amps 200-240V 3-Phase Motor, One Must Be Used on One Motor Only, Input/Output 200V-240V, Digital Type

came early. works well. great buy

I used this DPS unit on a 4.8 HP 3-phase Italian motor which was on an old stroke sander, wired for 230 volts. Wiring it up is brain dead simple. It took right off with plenty of power. I solved the rotation issue by switching 2 of the 3 leads for the 3-phase---got it fixed the first time. I thought this was a great / cheap solution--- way cheaper than rotary conversion.So it worked—— HOWEVER— this unit made my sander sound like a freight train (very alarming!) and I knew I was tearing it apart inside. I sent it back, then a local electric motor company made a different solid state converter for me, and that worked, but sounded like a jet engine in my garage!!Finally, I bought an American made rotary phase converter (after much down time) and my sander now runs PERFECTLY SMOOTH, like it should. So, save your time and money and get a REAL converter.

Finally got around to installing this unit on my 5hp 3 phase table saw. Seemed to work okay for the first few days. Then it would surge a couple times on start up before holding and working okay. Last night after running for maybe two hours off and on, the amperage limit tripped on the saws magnetic switch. Reset it and tried again and it started up and ran, but it sounded kinda weird, looked down and saw smoke pouring out of the DPS unit. Really sucks that I internationally bought a unit rated for 7.5hp to run a 5hp saw, just as I was advised, and felt good thinking I had plenty of overhead before I would overwhelm the unit. Smoked and fried in the first week. And no way to contact the seller through Amazon because I didn’t get around to setting it up for a few months and now I am out of the return policy time. Waste of money.

Good Deal.

This product saved me a bunch of money.The customer service is excellent and they answered all of my questions even on the weekend. I had ordered a 5.5 hp water pump online that cost over $1600.00 however did not realize that it was three phase. Then I was stuck. I didn’t want to pay the power company to install three phase so I started shopping around and found this. Very easy to hook up and has worked flawlessly for over 300 hours of run time now. This is the first amazon review that I have ever done and I have buying off of here for many years, that should tell you how impressed I am with this product. Thank you .

I purchased this Phase Shifter a little over a year ago and ir has performed flawlessly. I would of rated this four stars but it is very difficult to reach customer service. I had a problem but it ended up being something other than the DPS. But is was difficult to reach customer service, when I did reach them they were responsive and helpful. That is the only reason for it not being a five star review. The DPS was easy to install and has worked great.

I use this to power a compressor for a walk in cooler in a residential setting. It's been hooked up 3 years no problems yet.

Let me start by saying that I hired one of the best electrical companies in my area to do the install. It seemed to come together easily enough, but in the end my machine didn't work properly. It would turn on, and I would hear the motor running, and then once I put the motor into action, it would run very noisily until it shut off with an error code indicating that there wasn't enough power to make the motor run properly. Had an electrician come out and verify everything was hooked up correctly. It was hooked up correctly, but when we tested the three phases one wouldn't generate any power. U to V and U to W were reading the correct power out, but W to V was giving me no power. At this point I can only assume this is a faulty product. Now I'm stuck even longer with a very expensive piece of equipment generating no revenue for my business while I look at further options.
