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.

IP20 (part #'s ending in 2):
- Available up to 50hp, no disconnect switch
- 3 phase models can be derated by 50% for use in single phase power applications
IP66/NEMA 4X (part #'s ending in A or B):
- Ending in B is Outdoor, with disconnect switch
- Ending in A is Outdoor, no disconnect switch
- Outdoor rated, dust-tight and washdown ready!
- Please note: For IP66/NEMA 4X three phase input models, chassis size 4 is not capable of being derated for use in applications supplying single phase power to these units.
- Size 4 chassis use film capacitors which prohibit single phase operation.
