Baldor VS1MX41-4 Three Phase Variable Frequency Drive

The Baldor VS1MX41-4 is a 1 HP (0.75 kW) three-phase variable frequency drive designed for 460 V systems. It accepts 380–480 VAC, 50–60 Hz, three-phase input and provides a variable output up to 500 Hz with up to 500 VAC at the motor terminals, rated for 5 A input and 2.2 A output. The drive is housed in a NEMA 4-rated enclosure (listed as NEMA 4 or 4X/12 variants in some listings), making it suitable for washdown or harsh industrial environments. Footprint is roughly 6.3 in x 9.1 in x 6.9 in and the unit weighs about 8.5 lb (3.9 kg). As part of Baldor’s VS1MX general-purpose drive family, the VS1MX41-4 is used to control small three-phase motors in conveyors, pumps, and fans where a rugged, weather-protected controller is needed and 50/60 Hz mains are standard.
