Mitsubishi MR-J4-DU30KA-RJ AC Servo Drive for MELSERVO MR-J4 Series

The Mitsubishi MR-J4-DU30KA-RJ (MR-J4-DU30KA-RJ) is an AC motion servo drive amplifier engineered for motion control within the Mitsubishi Electric MELSERVO-J4 series. Equivalent to the MRJ4350GF4RJ, this unit provides precise motor regulation and control for automated production machinery and drive systems. This 400 V class drive features a rated power output of 3.5 kW (3,500 W) with a rated current of 8.6 A. It supports a main circuit supply voltage of 380 to 480 V AC on three-phase 400 V, 415 V, or 440 V AC lines, or a 283 to 340 V DC input. The amplifier incorporates an integrated dynamic brake, a built-in braking resistor, and compatibility with external safety units. For networking and motion control coordination, the device includes CC-Link communication capability. Housed in an enclosure with an IP20 ingress protection rating, the unit is rated for reliable operation in ambient operating temperatures ranging from 0 to +55 degrees Celsius.
