Mitsubishi MDS-DH2-SP-200 Spindle Drive Unit for MDS-DH2 Series

The Mitsubishi MDS-DH2-SP-200 (MDS-DH2-SP-200) is a high-performance spindle drive unit engineered for use with Mitsubishi MDS-DH2 series drive systems in computer numerical control (CNC) machine tools. Designed to provide precise speed and torque regulation for high-speed machining spindles, this unit ensures reliable operation in demanding industrial manufacturing environments. Operating on a 400 V class power architecture, the unit accepts a three-phase AC input voltage ranging from 380 V AC to 480 V AC (including nominal ratings of 400 V AC, 415 V AC, and 440 V AC) as well as a DC input voltage from 513 V DC to 648 V DC. The drive delivers a rated output current of 85 A to drive compatible spindle motors. Built with an IP20 degree of protection, the enclosure safeguards internal power electronics against solid objects while operating within an ambient temperature range of 0 to +55 degrees Celsius. The MDS-DH2-SP-200 is typically deployed in multi-axis milling machines, CNC lathes, and automated machining centers requiring consistent spindle velocity and rapid acceleration.
