Mitsubishi MR-J4-DU55KB4-RJ AC Servo Drive for MELSERVO-J4

The Mitsubishi MR-J4-DU55KB4-RJ (MR-J4-DU55KB4-RJ) is an AC motion servo drive and amplifier unit manufactured by Mitsubishi Electric for the MELSERVO-J4 series. Designed to deliver precision motion control in industrial machinery and automated production systems, this servo amplifier features an integrated dynamic brake and built-in braking resistor to manage regenerative energy and support dependable stopping performance. It is equipped with a multi-network interface offering EtherNet/IP communication capability, enabling seamless integration into multi-vendor industrial networks and distributed motion architectures. Operating on a 200 V to 240 V AC supply voltage across single-phase or three-phase power lines, the drive provides a rated output of 400 W (0.4 kW) and a rated current of 2.8 A. Built with an IP20 ingress protection rating, the unit is engineered for reliable operation within ambient temperature environments ranging from 0 to +55 degrees Celsius. It serves as an equivalent replacement to MRJ440TMEIP across diverse factory automation applications, including packaging lines, material handling equipment, and computerized assembly machines requiring responsive closed-loop servo control.
