Mitsubishi MR-J4-DU30KB-RJ Servo Drive Unit for MELSERVO-J4

The Mitsubishi MR-J4-DU30KB-RJ (MR-J4-DU30KB-RJ) is an AC motion servo drive unit designed for high-performance motion control within the MELSERVO-J4 series. Engineered for precision positioning and dynamic motor operation, this servo amplifier delivers a rated output of 3.5 kW (3500 W) with a rated current of 17 A. It operates on a three-phase 200 to 240 VAC supply voltage and incorporates both an integrated dynamic brake and a built-in braking resistor to ensure controlled deceleration and efficient energy management during heavy cycling. Equipped with a multi-network interface that supports EtherCAT communication, this drive unit enables rapid data exchange and synchronized multi-axis control across industrial networks. The unit features an IP20 degree of protection and is rated to operate reliably within an ambient operating temperature range of 0 to +55 degrees Celsius. It serves as a direct functional equivalent to part number MRJ4350TMECT, making it suitable for material handling, packaging machinery, assembly systems, and machine tool axes requiring robust servo drive performance.
