The INOVANCE MD200T0.4B 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 the 3-phase 380V input variant of the MD200 series, it brings sensorless vector control (SVC) to the most affordable price point in the Inovance lineup. Featuring a built-in braking unit, silent fanless design, and DIN-rail mounting capability, the MD200T0.4B is the perfect micro drive solution for compact OEM machinery, small pumps and fans, and cost-sensitive automation projects where 3-phase power is available and every millimeter of panel space matters.
