Product Description
The Benshaw RSI-020-H2-4C variable frequency drive (VFD) is rated for 20 horsepower at 460 volt 3 phase and is housed in a protected chassis IP20 enclosure. This next generation 30 AMP VFD is rated for both standard duty (20 H.P.) and heavy duty (15 H.P.) applications along with an Internal IGBT dynamic brake that comes standard. A fully functioning keypad with LCD screen allows for complete programming along with HAND and AUTO operations.
Looking for a 20 H.P. heavy duty rated drive? Try the Benshaw RSI-025-H2-4C to match that specification.
