Mitsubishi MDS-DH2-SP-320 Spindle Drive Unit

The Mitsubishi MDS-DH2-SP-320 (MDS-DH2-SP-320) is a high-performance spindle drive unit engineered for use in industrial CNC machine tools and automation systems. Part of the Mitsubishi MDS-DH2 series, this drive is designed to regulate and control spindle motors with precision and dynamic responsiveness, ensuring stable operation during demanding machining processes. This unit features a rated output current of 103 A and operates from a 400 V class power supply, accommodating input voltages of 380 to 480 V AC across three-phase connections (including 400 V AC, 415 V AC, and 440 V AC nominal ratings) or a 513 to 648 V DC bus input. Built for integration into industrial control cabinets, it possesses an IP20 degree of protection and is rated to operate reliably within an ambient temperature range of 0 to +55 degrees Celsius. The drive serves as a critical component in CNC machining centers, milling machines, and lathes requiring accurate spindle speed and torque management.
