Product Description
The Benshaw RSI-050-S4-4W is a 50 horsepower at 460 volt variable frequency drive (VFD) that is rated for 65 AMPS standard duty. This wash down VFD is housed in a NEMA 4X polycarbonate enclosure and can withstand the harshest of elements while providing the superior reliability and performance that you have come to expect from Benshaw drives. Sensorless vector control along with a standard braking transistor are included in the RSI-050-S4-4W which make it the most comprehensive out of the box variable frequency drive available in the market today. If you require a 50 horsepower heavy duty rated VFD, check out the RSI-060-S4-4W for a higher rated option.
