Description

Mitsubishi MDS-A-CV-300

An essential part of CNC machine tools, the Mitsubishi MDS-A-CV-300 Power Supply Unit is made to supply DC currents to Mitsubishi MDS Spindle Drives and Servo Drives. This power supply unit guarantees that your machine runs as efficiently as possible because it is designed for maximum performance and dependability.

Technical Description:

The MDS-A-CV-300 is specified with a rated input of 3AC 200-230V at 107A and a maximum rated output of DC 270-311V at 144A, boasting a capacity of 30kW. This substantial power capability underscores its suitability for demanding CNC applications, precisely supporting servo and spindle drives.

One of the notable features of the MDS-A-CV-300 is its efficient cooling system. The unit operates a cooling fan at the rear, ensuring optimal thermal management even under high loads. Proper placement next to the MDS Spindle Drive Unit, as the MDS manual recommends, is crucial for maintaining orderly connection and efficient operation.

In terms of thermal performance, the use of power supply regeneration in the servo drive significantly reduces heat generation. This efficiency, combined with the integration of the IPM, ensures that the MDS-A-CV-300 remains cool and reliable under heavy operational demands.

The MDS-A-CV-300 is equipped with a high-speed CPU on the control PCB and a 100,000 pulse/rotation sub-micron detector for high-speed and precision processing. This setup allows faster and more precise interpolation, improving positioning time tracking and reducing machine vibration during acceleration and deceleration. The high-speed spindle orientation feature also ensures smooth operations and minimal orientation times, enabling direct orientation from high speeds during spindle drive operations.

Compatibility:

The MDS-A-CV-300 belongs to the MDS-A Series, a drive system compatible with the MELDAS M500 Series NC. This series was developed to integrate servo and spindle drive sections seamlessly. The subsequent MDS-B Series, designed to meet European Safety Standards, carries forward these innovations with enhanced safety and performance features.

Key features of the MDS-A-CV-300 include its compact and lightweight design. By integrating converters previously built into individual servo and spindle drives into a single unit, Mitsubishi has drastically reduced the drive system volume, installation area, and weight. This integration is achieved through high-density mounted electronic parts, including the Intelligent Power Module (IGBT-IPM) and a high-performance heat-radiating fin.

Applications:

The Mitsubishi MDS-A-CV-300 Power Supply Unit is crucial for various industrial applications, particularly in CNC machining. It provides DC power to servo and spindle drives, ensuring precise control and high-speed operations in CNC machining centers, lathes, and grinding machines. This unit supports accurate and smooth movements for milling, drilling, turning, and grinding tasks. It is also used in EDM machines, laser cutting machines, and robotic systems for precise control and repeatability. Additionally, it enhances efficiency in injection molding, textile machinery, and packaging processes.
