ATO 5hp VFD, 220V Single to Three Phase VFD Variable Frequency Drive, 5hp 3.7 kW VFD 220V-240V Single Phase Input 0-220V 3 Phase Output VFD for AC Motor Speed Control(1-Phase Input, 3-Phase Output)

I have purchased a total of four ATO single to three phase drives now.- First was a ~18kW drive for a stone wire saw. That drive worked very nicely out of the box with easy setup. Then we cut plenty of big rocks.- Now three of these smaller 3.7kW models for 5 HP blower motors. All working well out of the box. I don't have years of hard usage on these drives but I will say off to a good start. There were cheaper options but I went with ATO because they had good performance previously.ATO seems to have their act together. The videos on line help a lot. As usual for a Chinese company the documentation could be better but hey the docs are pretty good for the simple use cases I have for them.Five stars and two thumbs.

We have an old lathe from the 40's with a 5 hp sleeve bearing motor and it works great! Easy to set up, handles a heavy load, lots of features like reverse or jog reverse and forward. Absolutely recommend these units.

VFD was purchased to operate a 3ph sander on a single phase service. Very easy to install, clear directions, and reasonable price. VFD functioned as intended with an added bonus of being able to control sander speed.

I bought this for a 3 hp motor and can’t get it to work. Sent an email to ATO twice and never got a response. Very disappointed in this product.
