Mitsubishi MDS-EH-CV-370 AC/DC Power Supply Converter Unit for MDS-EH Series

The Mitsubishi MDS-EH-CV-370 (MDS-EH-CV-370) is an AC/DC power supply converter unit designed for high-performance MDS-EH series servo and spindle drive systems. Operating as a central power conversion stage in CNC machinery, this unit converts incoming three-phase AC or DC input power to stabilize the common DC bus that feeds multiple servo drives. It delivers a rated output capacity of 30 kW with a rated current of 82 A. The supply voltage supports a 200 V class range of 200 V AC to 240 V AC at 50/60 Hz, outputting a steady DC bus voltage ranging from 513 V DC to 648 V DC. Engineered for demanding industrial environments, the converter features an IP20 degree of protection to shield internal circuitry from solid contaminants. It operates reliably within an ambient operating temperature range of 0 to +55 degrees Celsius. The MDS-EH-CV-370 is widely deployed across automated machining centers, machine tools, and multi-axis CNC systems requiring dependable power management and stable bus supply.
