Mitsubishi MDS-EH-CV-550 AC/DC Power Supply Converter Unit for MDS-EH Series

The Mitsubishi MDS-EH-CV-550 (MDS-EH-CV-550) is an AC/DC power supply converter unit designed for Mitsubishi MDS-EH series drive systems. Operating within high-performance CNC machinery and multi-axis servo configurations, this unit rectifies three-phase AC or DC input power into a stabilized DC bus supply to power compatible servo and spindle drive amplifiers. It delivers a nominal output power of 45 kW with a rated current of 119 A, ensuring consistent energy delivery during rigorous machining cycles. The converter operates from a three-phase 200 V to 240 V AC supply (200 V class, 220 V or 230 V AC) or direct current input, generating an output voltage range of 513 V to 648 V DC. Engineered with an IP20 ingress protection rating, the MDS-EH-CV-550 is built for enclosed cabinet installation and is rated for ambient operating temperatures from 0 °C to +55 °C. Typical applications include high-precision CNC machine tools, machining centers, and automated manufacturing equipment requiring reliable regenerative DC power conversion.
