Mitsubishi MDS-DH-CV-370 Power Supply

The Mitsubishi MDS-DH-CV-370 is a 30 kW power supply unit from the MDS-DH series, designed to supply DC bus voltage to Mitsubishi MDS servo drives and spindle drive modules in CNC machine tool applications. The nameplate identifies a three phase input rated 70A at 380 to 440V or 380V at 50/60 Hz, with a single phase auxiliary input of 0.1A at 380 to 440V or 480V at 50/60 Hz, and a DC output of 82A across the 513 to 648V DC bus range.

The unit carries UL Listed Industrial Control Equipment certification (88R2), CE marking, and TV Rheinland Bauart Geprüft Type Approved markings (EN 50178). Identifiers on this specific unit include manual number IB-1500002, software designation BND588W000A3, hardware version L, serial number J3A4XG58WBQ, and a date code of 07/08. Cooling is provided by two rear mounted fans drawing air through an internal heatsink assembly. The chassis is constructed for side by side mounting against MDS spindle and servo drive units sharing the DC link.

The MDS-DH-CV-370 is commonly installed in Mitsubishi M700, M70, and M70V series CNC controlled machining centers and lathes that use the MDS-DH drive platform. It functions as the regenerative power supply for the high voltage 400V class drive line, converting incoming AC to the DC link voltage required by the connected spindle amplifier and servo amplifier modules. The unit must be placed adjacent to the largest capacity spindle drive on the NC communication bus per the MDS manual. MPN MDS-DH-CV-370. Manufactured in Japan by Mitsubishi Electric Corporation.
