Mitsubishi MDS-EH-CV-450 AC/DC Converter Unit for MDS-EH Series Servo Drives

The Mitsubishi MDS-EH-CV-450 (MDS-EH-CV-450) is an AC/DC power supply converter unit engineered for use with Mitsubishi MDS-EH series multi-axis servo drive and spindle drive systems. Operating within industrial machine tool automation environments, this converter supplies regulated direct-current power across a common DC bus to coordinate multiple drive axes smoothly and efficiently. Technically, the MDS-EH-CV-450 delivers a rated output capacity of 37 kW and a rated output current of 99 A. It accepts a three-phase AC input or direct DC input voltage ranging from 200 to 240 V AC (200 V class, 220/230 V AC nominal), converting it into a rectified intermediate DC link output of 513 to 648 V DC. The unit features an IP20 protection degree housing and is rated to operate reliably in ambient temperatures from 0 to +55 degrees Celsius. Built to support demanding multi-axis CNC machines and production lines, this converter unit delivers dependable power distribution, stable bus voltage control, and robust thermal performance under heavy operational loading.
