I've only had this a few days. I will try to keep this review updated as I go. Initially, I'm a little disappointed that mine didn't come with a rotary knob as it is in the pictures. I should be able to wire a potentiometer to do the same thing once it's all set up, but that would have been nice to have. After looking closer, some of the picture don't have the knob in it. I have no idea what that means for anyone else getting this. The manual feels a little lacking. I was hoping for more detailed installation instructions as I've seen other's have on higher end VFD's. I'll be using this to run a large metal lathe. I have yet to connect it to power, but everything looks to be in order. I was hoping to have specific installation information like, how large of a breaker works best, if a fast acting fuse is needed, rf filter, anything like that. I get they can't recommend information for every country, but I was still hoping. I emailed the seller(they emailed back within 2 days so that's a big positive), and they basically said what the manual mentions. Connect 220v single phase to the 2 terminals mentioned in the manual, and wire the motor to the output terminals. We will see. running this much power has me a little skeptical, but I will figure it out. Again, I will try to come back and update once I've got it running. I don't yet know if I recommend it or anything else. It's definitely the cheapest option for converting this much power.Read full review

I received the item very quickly and was immediately surprised by it's small size. I have not installed it yet, but I am really looking forward to using it to (partially) replace an old, noisy, and expensive-to-replace rotary phase converter. I purchased the item on the recommendation of a friend who runs his whole shop with one unit the size of half a loaf of bread. Impressive. Unfortunately, I may eventually need more than one unit to do that in my shop, but the total cost will still be a fraction of the replacement cost of the rotary converter.

I used this to power an old 10Hp metal turning lathe. We don't have 3 phase power in our garage and I didn't want to get a phase converter. This VFD was easy to set up, cheaper to buy than a phase converter, and made the machine safer to operate. I am only running the lathe at 60Hz for now, but tested the variable speed and it works great. Nice and smooth. I may be back for another VFD once I get my hands on a milling machine.

So far so good. Have it on a 10hp IR compressor. Starts and stops it no problem, with a little tweaking on the accel/decel. At full pressure, the unit draws 56 amps at 240 on the single phase input. Motor never draws more than 24 amps. I have the pressure switch closing the start/stop input (pe 04). I do have a toggle in the input line so I can turn on the vfd and let it boot before it starts the compressor motor.

Easy hook up and runs my 3 phase 5HP Varidrive motor just fine. Fan only runs when it is sending power to the motor, that's a good thing. Tried using a YH 5hp VFD, but would not work in my situation of varying heavy load. The YH VFD kept giving me over voltage error, this one handles the load perfectly.
