MDX61B0450-503-4-0T MOVIDRIVE® B Series AC Drive | SEW-EURODRIVE

MDX61B0450-503-4-0T is a 45 kW (Constant Torque) high-performance AC drive from SEW-EURODRIVE MOVIDRIVE® MDX61B series. It is equipped with an integrated brake chopper for four-quadrant regenerative operation. There is no built-in EMC filter, so an external EMC filter must be applied on site. The suffix 0T means the PCB is conformal coated, making it suitable for humid, dusty and mildly corrosive harsh industrial environments.
