Purchased this as a retrofit to a 40 y...ear old air conditioning condenser to quiet it down, save energy and improve pressure control. Relatively easy to set up. Can use either single or three phase input power to drive a 3 phase motor. Made initial setup of the drive with the motor at home easy. Only down side is the documentation is sometimes unclear or has outright mistakes in it (Chinese to English translation). There is NO mechanical information about mounting the drive to be found at all - a mounting and outline diagram would be extremely helpful.

I rebuilt an old Hobart 5HP 3phase meat grinder fo...r my processing business and needed a way to run it off single phase. The previous owner used a phase converter, which drew high amperage on start up and was very harsh on the irreplaceable motor. Well, we couldn't have that. This drive fit the bill perfectly. I got the drive about one week after purchasing on E'bay and, after a quick wire up and a bit of programming, had the big Bart running. The motor starts up real smooth and actually draws less amperage then expected. I highly recommend this drive for those whom do not have three phase power.

This unit raised... the ceiling to motor compatibility with my production machine. While I could never run a 7.5KW motor on the circuit, it has the flexibility to match a required output power.

I have purchased some dozen Huanguang VFDs. We are runn...ing pumps, machine tools, air compressors, HVAC compressors etc. The are powered by a large solar system. They are difficult to program but I have been able to figure them out and have never tried to contact company. The main prob I have had is equipment that runs high duty cycle like heat pumps. The VFDs tend to burn up their electrolytic caps in about a year or two. Now, when we install them on heat pumps, I Install a VFD with about 3 times the capacity. For example the 10 HP VFD I am ordering now will go on a 3 1/2 Hp heat pump. I have had no problem since I started this policy 4 yrs ago. Km
