Mitsubishi MR-J4-DU30KB4-RJ-(B) AC Servo Drive MELSERVO MR-J4

The Mitsubishi MR-J4-DU30KB4-RJ-(B) (MR-J4-DU30KB4-RJ-(B)) is an AC servo drive unit designed for motion control applications within the MELSERVO MR-J4 series. Operating on a three-phase 380 V to 480 V AC supply voltage across the 400 V class, including 400 V, 415 V, and 440 V AC systems, this servo amplifier delivers a rated output of 3,500 W (3.5 kW) with a rated current of 8.6 A. It features a built-in dynamic brake and an integrated regenerative braking resistor to ensure controlled deceleration, energy dissipation, and reliable stopping under demanding operating conditions. Equipped with a multi-network interface supporting EtherCAT communication capabilities, the drive integrates seamlessly into distributed motion networks. The unit provides an IP20 degree of protection and is rated for operating ambient temperatures ranging from 0 to +55 degrees Celsius. Delivering high positioning accuracy and rapid dynamic response, it also functions as an equivalent to model MRJ4350TM4ECT in multi-axis machinery, robotics, and high-performance production equipment.
