Review: DID NOT WORK - 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.
Review: Failed in first week. - 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 desertcart 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.

## Questions & Answers

**Q: The motor runs fine with the DPS connected, then suddenly stops running.**
A: Check to see if the motor is overloaded. The motor should be at 90% load or less. Also, make sure that the DPS model matches the motor capacity. It is possible that the DPS components are damaged due to overcurrent.

**Q: The motor runs with the DPS connected, but the power is weak.**
A: Make sure the input voltage and wattage are normal and check the motor load. Also, make sure that the DPS model matches the motor capacity.

**Q: The motor slows down and does not run smoothly.**
A: Please check the motor load and use it with a load condition of 90% or less (overcurrent phenomenon due to overload).

**Q: The output current and voltage of the motor is too high, causing overheating and noise.**
A: Make sure that the DPS model is correctly selected for the motor capacity. This is caused by using a DPS with a capacity that is too high for the motor capacity. Also, check if the motor is overloaded.

**Q: Can the DPS be used with heaters, ovens, or sunbeds?**
A: For heating equipment such as ovens, DPS operates at an efficiency of approximately 70%, which is lower than the standard 90% efficiency. Lower efficiency may result in extended heating time compared to normal operation.
