SEW MDX61B0550-503-4-00 Inverter Drive – 55kW, 105A, IP00

The SEW MDX61B0550503400 is a high-capacity frequency inverter drive from the MOVIDRIVE® B series, engineered for maximum power delivery and precision control in industrial heavy-load applications.

Designed for linear and square motor loads, this inverter supports 55 kW output for linear motors and up to 75 kW for square-load motors. It accepts a 3-phase input of 380–500 V AC ±10% at 50/60 Hz ±5%, drawing 94.5 A, and delivers 105 A output current at up to 73.5 kVA.

This unit is housed in an IP00 open-frame chassis, making it ideal for protected cabinet installations in temperature-controlled industrial environments up to +40°C.
