DPS Single Phase to 3 Phase Converter, MY-PS-7.5, Best for 5Hp(3.7Kw) 15 Amp 200-240V Motor, Should Only Be Used for One Motor per One, Input/Output 200V-240V

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.

I purchased this unit to do a 3 phase conversion on a 5.3 HP CNC Spindle. My plan got changed so I really did not even use it or hook it up. The support from the seller was absolutely great. They were very helpful and insistent on ensuring you are ordering the right product immediately after your order is submitted. These units are for single driver only and each model is designed for a certain Horsepower rating. The Item came almost 3 weeks early from the estimated shipping duration.

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.
