SEW MOVIDRIVE MDX61B0750-503-4-00 | 75kW General Purpose Inverter

SEW-Eurodrive MOVIDRIVE B MDX61B0750-503-4-00 — 75kW, 3-phase 380-500V AC, 130A output, 91kVA, EtherCAT/PROFIBUS/Modbus, Size 5 drive.

Overview

The SEW-Eurodrive MOVIDRIVE B MDX61B0750-503-4-00 is a high-power Size 5 industrial frequency inverter rated for 75kW under constant load — one of the largest capacity units in the MOVIDRIVE B general-purpose family. It accepts a 3-phase 380–500VAC input at 50/60Hz, drawing a nominal input current of 117A (at 400VAC), and delivers a rated output current of 130A with 91kVA of apparent output power across a 0–400Hz output frequency range.

Communication capability remains extensive at this power level too: RS485 Modbus RTU is built in, alongside support for Ethernet, EtherCAT, Fieldbus, PROFIBUS, and SBus, so this drive integrates just as readily into existing plant automation networks as the smaller MOVIDRIVE B models. Onboard PID control and V/f control mode round out the control feature set, and the I/O configuration (2 analog inputs, 8 digital inputs, 2 analog outputs, 5 digital outputs) supports demanding machine control logic. A 150% overload capacity for one minute provides real headroom for load spikes on high-power equipment, and acceleration/deceleration times remain adjustable from 0 to 6000 seconds for precise motion tuning.

Available in IP00, IP10, or IP20 enclosure options, the drive measures 280 x 610 x 330mm and weighs approximately 35kg — a substantial unit reflecting its position at the top of the standard MOVIDRIVE B power range. It’s rated for 0°C to +40°C operation (storage from -25°C to +70°C).
