Mitsubishi MR-J4-200A-EG AC Servo Amplifier for MELSERVO MR-J4

The Mitsubishi MR-J4-200A-EG (MR-J4-200A-EG) is an AC motion servo drive and amplifier developed for the MELSERVO MR-J4 series to deliver precise motion control in automated industrial systems. Operating within the 400 V class, this unit accepts a three-phase 380 V to 480 V AC power supply, including nominal 400 V, 415 V, and 440 V AC inputs. It provides a rated power output of 15 kW and a rated continuous output current of 41 A, making it functionally equivalent to the MRJ415KA4 specification. Engineered with built-in RS-422 and RS-485 communication interfaces, the drive ensures reliable serial networking and rapid parameter transmission with upstream automation controllers. The enclosure features an IP20 degree of protection and is rated to operate reliably within an ambient operating temperature range of 0 to +55 degrees Celsius. This servo amplifier is typically employed in demanding motion control and multi-axis machinery, providing dynamic speed, torque, and position regulation across production lines, packaging equipment, and material handling systems.
