Review: Very good - Very easy installation and work good
Review: Not worthy of 1 star - Would give this product less than one star if I could. Does not work like advertised and is not really a digital phase converter. It is just a static converter with a solid state relay. Took it apart to investigate after realizing the voltages and currents were way off and it was past my return window.

A: Hello! Thank you for your kind inquiry.
Regarding your question, if you want to use DPS, the input voltage must be 200V-240V.
Also, DPS need not a ground line.
Please contact your electrician and make 200V-240V input voltage.
Have a good day!

**Q: Is the my-ps-1 compatible with a 3phase vfd to control speed of a 3phase motor (0.5hp)?  (vfd=powerflex 525)**
A: Hello. Thank you for your kind inquiry.

Regarding your question, you could use MY-PS-1 model for your 200V-240V 0.5HP motor with 0.5HP VFD.
Have a good time.

**Q: I have a band saw with a 1/2 hp 2.36a three phase motor on it. Will the my-ps-1 work or do I need to use the my-ps-2? The motor was made in the 40's.**
A: Hello! Thank you for your kind inquiry.
Regarding the rated current, it is too high compared to horsepower.

### ⭐⭐⭐⭐⭐ Very good
*by I***R on May 10, 2024*

Very easy installation and work good

### ⭐ Not worthy of 1 star

### ⭐⭐⭐⭐ A niche tool for a niche application range.
*by D***E on September 5, 2024*

This is a really interesting solution to a problem I've run into several times: Wanting to use a 3-phase device in a residential setting. However, it does have it's drawbacks. Do not attempt to use this thing with a digital system that requires 3-phase, such as an AC servo amplifier, or a digitally controlled CNC machine. Those applications require near-perfect phase balance, which this cannot supply. I would also advise against using this with motors rated for more than half the amperage that this is rated for. Otherwise, this thing works just as advertised. I have one of these running a small 0.8 amp coolant pump for a milling machine in my garage, and I have one of the larger models running the motor that drives the spindle. It works far better than limping my machine along on just 2 of the 3 phases.
