Mitsubishi MR-J4W03PWBRCBL2M-H AC Servo Amplifier for MELSERVO MR-J4

The Mitsubishi MR-J4W03PWBRCBL2M-H (MR-J4W03PWBRCBL2M-H) is an AC motion servo drive amplifier designed for the MELSERVO MR-J4 series. Engineered for precision motion control in industrial machinery, this unit features a built-in dynamic brake, an integrated regenerative braking resistor, and full compatibility with functional safety units. It delivers a rated output of 5 kW (5,000 W) with a rated current of 14 A. The drive operates with a three-phase supply voltage rating of 380 V AC to 480 V AC (400 V class, including 400 V, 415 V, and 440 V AC) or a DC input range of 283 V DC to 340 V DC. Built-in serial communication capabilities include RS-422 and RS-485 interfaces for drive configuration and monitoring. Housed in an IP20-rated enclosure, the unit is rated for ambient operating temperatures from 0 °C to +55 °C. Equivalent to the MRJ4500A4RJJ001 specification, it is commonly applied in multi-axis automation, packaging machinery, material handling, and automated positioning systems requiring dynamic servo performance.
