Description
INOVANCE MD200T3.7B-INT 3.7 kW Variable Speed Drive, 380-480 V, 3 Phase
The INOVANCE MD200T3.7B-INT is a compact, general-purpose AC drive designed for reliable motor speed and torque control in three-phase industrial applications. It supports open-loop V/F control and Sensorless Vector Control (SVC), providing up to 150% starting torque at 3 Hz in SVC mode.
With a 3.7 kW (5 HP) motor capacity, 380–480 V three-phase input, and 9.5 A rated output current, the MD200T3.7B-INT provides flexible motor control through automatic torque boost, slip compensation, programmable I/Os, DC injection braking, built-in dynamic braking, and Modbus RTU communication.
The MD200 series offers a maximum output frequency of 500 Hz and supports side-by-side, wall-mounted, and DIN rail installation. Its IP20 enclosure and Class 2 conformal coating provide enhanced protection against humidity and dust pollution. The drive can operate at ambient temperatures up to 50°C, with derating required above 40°C.
