Mitsubishi MR-J4W03PWBRCBL10M-H Servo Amplifier for MELSERVO MR-J4 Series

The Mitsubishi MR-J4W03PWBRCBL10M-H (MR-J4W03PWBRCBL10M-H) is an AC motion servo drive and amplifier developed for the MELSERVO MR-J4 series by Mitsubishi Electric. It features a rated output of 5,000 W (5 kW) and a rated current of 14 A, operating on a three-phase 380 V to 480 V AC power supply across the 400 V class, including 400 V, 415 V, and 440 V AC systems. This unit incorporates an integrated dynamic brake and a built-in regenerative braking resistor to manage energy dissipation during motor deceleration. The servo amplifier is equipped with RS-422 and RS-485 serial communication capabilities for system interfacing and control. It features an IP20 ingress protection rating and is rated for operation in ambient temperatures ranging from 0 to +55 degrees Celsius. Functionally equivalent to MRJ4500A4, this drive provides precise speed and position control for compatible MELSERVO J4 motion systems.
