Mitsubishi MR-J4-DU37KB Servo Drive Unit for MELSERVO MR-J4 Series

The Mitsubishi MR-J4-DU37KB (MR-J4-DU37KB) is a high-performance AC servo drive unit designed for motion control applications within the Mitsubishi Electric MELSERVO MR-J4 series. Equipped with high-speed SSCNET III/H optical communication, this drive delivers synchronized multi-axis control and rapid response times in automation environments. It integrates a built-in dynamic brake, a built-in braking resistor, and safety unit compatibility to ensure operational protection and rapid stopping under emergency conditions. The unit operates with a rated output of 0.4 kW (400 W) and a rated current of 2.8 A. It supports a supply voltage rating of 200 to 240 V AC across 200 V class power networks, as well as 283 to 340 V DC input, accommodating single-phase (2P), three-phase (3P), or direct current configurations. Housed in an IP20 protective enclosure, the MR-J4-DU37KB is rated for operating ambient temperatures ranging from 0 to +55 degrees Celsius. It provides reliable and precise motion control across industrial machinery, packaging systems, robotics, and automated production lines requiring MELSERVO J4 motion architectures.
