Bill what was that step up transformer system? I know you can step up the voltage but how dose the 3 phase bit work?
It's simply that the higher voltage vfds tend to be cheaper on ebay than 240v ones.

A 1Kw VFD needs a 16A circuit so not practical to put it on a 13A plug.
Irving, my 1k5 vfd runs on a 13a plug albeit via a transformer.
