The INOVANCE MD200S0.4B is an ultra-compact micro variable frequency drive delivering 0.4 kW (0.5 HP) for precision speed control of small three-phase asynchronous AC motors. As part of Inovance's most affordable MD200S series, it accepts single-phase 220V input and outputs 3-phase 220V to drive small motors with sensorless vector control (SVC) technology. Featuring a built-in braking unit, silent fanless design, and DIN-rail mounting capability, the MD200S0.4B is the ideal drive for compact OEM machines, small pumps and fans, and cost-sensitive automation projects where space and budget are at a premium.
