Mitsubishi MR-J4W03PWBRCBL20M-H Servo Drive for MELSERVO MR-J4

The Mitsubishi MR-J4W03PWBRCBL20M-H (MR-J4W03PWBRCBL20M-H) is an AC motion servo drive engineered for high-performance motion control within the Mitsubishi Electric MELSERVO MR-J4 series. This servo amplifier provides a rated power output of 5 kW (5,000 W) and a rated current of 14 A, delivering reliable speed, torque, and position management for compatible industrial machinery. It includes an integrated dynamic brake, a built-in braking resistor, and compatibility with safety units, making it equivalent to the MRJ4500A4RJJ001 drive configuration. Designed for demanding factory automation applications, the drive operates on a three-phase 380 V to 480 V AC supply (400 V class) or a 283 V to 340 V DC input. The unit features built-in RS-422 and RS-485 communication interfaces to facilitate efficient integration with motion controllers and automated production systems. Housed in an IP20-rated protective enclosure, the amplifier is rated for reliable operation in ambient operating temperatures ranging from 0 to +55 degrees Celsius.
