AC 220V Variable Frequency Drive Single Phase Input to 3 Phase Output Frequency Converter VFD Inverter for Spindle Motor Speed Control (0.75KW 1HP 5A)

Amazing nice for the price, highly programmable, yet easy to setup with basic knowledge. For my purposes, I just needed to change hz from the European standard of 50 cycles/second, to the US standard of 60 cycles/second, I also limited frequencies to 30% at the lower end and 60% at the high end to make things a bit easier on my equipment. Works great so far.

Received with massive internal damage. The damage is so severe (see picture) that it's hard to imagine it happening in shipping. The damage is more likely the result of the product being crudely slapped together by incompetent, cheap labor, and never tested before leaving the factory. Note that the circuit board's plastic mounting boss has completely broken free of the housing. The inverter would have to have been dropped twenty feet for that sort of damage to happen. It's far more likely that it was shipped out that way. Unfortunately, I'd already fabricated a mounting plate and wiring harness for this project before noticing that it was junk, so now all my work is wasted. I will be asking for a refund, but I certainly will not risk ordering another one of these pieces of junk!

Works great on my lathe.
