Used for 2HP(1.5kW) 6A Motor, Single to 3 Phase Converter, My-PS-3, 1 DPS Must Be Used for 1 Motor Only, Input/Output 200-240V, UL Listed | For 2HP(1.5kW) 6A Motor, Input/Output 200-240V, UL-Listed, 1 DPS per 1 Motor Only, Easy Set Up, Digital Phase Shifter

I needed it to power up my 3 phase 2hp 2J head BP mill. Rotary convertors were a little on the steep side as well as phase invertors. This guy works great. The directions are pretty good, but might a little vague for someone with who's not an electrician or has knowledge of 3 phase power, phase rotation etc. But even then, its something they should not be attempting if that's the case. I ran a dedicated 20amp 240v circuit for it and put a 2 pole disconnect in front of it. As most digital convertors and VFD's create phase interference and distortion on the lines without filters. So the disconnect stops any of that when not in use. Then put it on a 3 pole contactor with 120v coil so the mill head gets no power unless for immediate use. Then from the contactor to the drum switch on the mill head. Make sure the phasing is correct for the rotation so when the drum switch is put into low range it spins correctly and the same in high range. Had it installed now for like 5 months now and runs great. Also make sure you get the right size for your motor load. Getting one of these too small, will over drive the unit and burn it out. Getting one too large will underdrive the DPS and not create the ideal 3rd phase sine wave. The unit creates the 3rd phase immediately after the motor is turned on. So it's not ideal from a start up standpoint, but under operation it's fine. Ideally maybe a cap bank as a buffer or a VFD ramp up would be best, but then you're getting into a serious investment. For the weekend machinist project work I do, its perfect. If you're looking at this for full time, professional power solution; a rotary convertor or getting a 3phase service would be best.

Purchased to run a 2 hp 3 phase motor on a Bridgeport mill. Wired it up and it worked. Motor started and ran. Then experienced that the motor would drag on start up. Checked voltages between phases and found 60 volt variations between phases. I can’t continue to subject my equipment to this.

First I bought other brand with bigger size, the motor started to get very hot in seconds. But this one with the recommended size works very well, I run it for 10 minutes without loud and no heat, I cut 50 cuts in peace of hard maple the motor shows no significant heat. I don’t know about the long term usage of this phase converter but it seems it has very good potential.

I was using a VFD, but you cannot do a hard reverse with the one I had without faulting out, Nearly built a rotary phase converter then I found this. Supper simple to wire up. Behaves just like 3 phase power. And costs pennies on the dollar. Only had it for a couple of months but so far so GREAT

It worked! I finally got a surface grinder up and running. This is so far the easiest phase converter that I've ever installed. Wiring is simple and straight forward. Two hot wires in, three hot wires out. But, there is no connection for a grounding. YOU MUST HAVE A GROUNDING WIRE! Every component must be grounded from the main panel to the disconnect, to the switch, to the machine you're running. Easy enough, just go around this converter with a grounding wire. Doesn't look the best but it works. Since the wire connections on this converter are inadequately covered place this device where you are less likely to come into contact with it. Be safe UPDATE! Used this device to burn out one motor, and came seriously close to destroying a second one. It may work, but you’re taking your chances. We’re taking the knowledgeable advice of an electric motor repair tech and getting a rotary phase converter. Motors ain’t cheap! Especially when some equipment has its own special (and darned hard to find ) parts. Thank you!

Running my 3 phase table saw. Make sure your switch is before the converter.

I went this route over a VFD simply for the ease of install and that was a mistake. This is wired the same way as a static converter so no need to redo the wiring to and in your drum switch to work with a vfd, simply wire U to 1, V to 2, and W to 3. I did all that and the motor spun at maybe 30 rpm so i turned it off and began trouble shouting, Double check wiring first and it was correct. Next I checked voltage to ground output and things got crazy. It was feeding 2 legs 120 and the third was all over the place from 12-180 volts. When i checked voltage across the 3 legs to each other it confirmed it. I wrote the seller with my findings and they didn't even address the voltage issue. They told me to keep trying different variations of wiring and that i would eventually succeed lol. I'm embarrassed to say that I did try that but had the same results. My motor is good and i believe this unit was defective with the phase sequence not working and the voltage balance also not working.

I bought this for a 1.5 hp motor on my engine lathe. It will not balance the phases unless the motor is loaded. For light loads like polishing or finish passes it leads to a 3 Amp phase imbalance. I will keep the product even though it won't work for this. It will work perfectly for something like an air compressor.

works fine, it's amazing

Solo falta que de nfabrica tenga protección de sobrecarga

No me gustó el motor se calienta y no recibo respuesta del proveedor, ya que se consultó con el previamente ante de comprarlo.

I bought this, and even after reading the reviews, I thought I would be safe. Well I should have heeded the warning! Just about burned my 2hp motor on my milling machine after 3 min of running time. Absolutely no help from the seller at all. And told me that it " would technically not damage the motor, if it was running too hot" and now will not respond to any of my emails at all. Once they have your money, they don't care. Please, do yourself a favor, and don't gamble on these. Find a more reputable seller and don't get burned like I did. Balance rates on every aspect were way out on voltage and amperage! I read several reviews that stated this same thing, and I thought, "ah, must be just a bad unit" but nope. Don't risk it!!

Sin ningún problema funcionó Perfecto, lo recomiendo, se uso en motor de 3 fases a 220V
