The Optidrive E3 from Invertek is a general purpose sensorless vector drive that is great for most motor types.

E3 series, 3 phase rated drives (with the exception of Size 4 IP66/NEMA 4X models) can be derated by 50% for use in single phase power applications. Please see more information under 'Documents'.

Invertek offers single phase input drives up to 10 hp, these drives are not derated.
