Mitsubishi MDS-EH-CV-300 AC/DC Power Supply Converter Unit

The Mitsubishi MDS-EH-CV-300 (MDS-EH-CV-300) is an AC/DC power supply converter unit developed for Mitsubishi MDS-EH series multi-axis drive systems and CNC machine tool applications. Operating as a centralized power supply stage, the converter rectifies incoming electrical supply to deliver a continuous direct-current bus voltage that powers paired servo amplifiers and spindle drives. Engineered for demanding industrial operations, this unit delivers a rated output of 26 kW and a nominal output current of 72 A. It accepts a three-phase alternating-current input or direct-current input within the 200 V to 240 V AC range for 200 V class power systems, accommodating 220 V and 230 V AC nominal supplies. The converter produces a regulated DC link output ranging from 513 V DC to 648 V DC. Built with an IP20 ingress protection rating, the unit is intended for installation within protective control cabinets and operates across an ambient temperature range from 0 to +55 degrees Celsius, providing stable performance and protection for high-precision machining environments.
