Description
ELAU MC-4/11/50/400 High Power PacDrive Digital Servo Drive
ELAU MC-4/11/50/400 is a heavy-duty high-current PacDrive digital servo drive belonging to Schneider Electric motion control lineup, specially designed for high-power synchronous servo motor closed-loop motion control in heavy-load automated production lines. This ELAU MC-4/11/50/400 adopts 3AC 380–480V main power supply with 50A continuous rated output current and 125A 1-second peak overload capacity, matching servo motors up to 35kW. As the high-power flagship unit of ELAU MC-4 series, MC-4/11/50/400 integrates internal brake bleeder, STO safety torque-off function and multi real-time industrial bus interfaces, widely deployed in heavy packaging machinery, large-format printing, metal forming equipment and high-load robotic handling systems.
