Mitsubishi MR-J4-15KA-RJ AC Servo Amplifier for MELSERVO-J4 Series

The Mitsubishi MR-J4-15KA-RJ (MR-J4-15KA-RJ) is an AC motion servo amplifier drive engineered for high-performance motion control within the MELSERVO-J4 series. Operating on a 200 V class AC supply voltage rated at 200 V to 240 V AC (suitable for 220 V or 230 V AC), this drive supports both single-phase two-pole (2P) and three-phase three-pole (3P) power input. It delivers a rated output of 11 kW with a rated current of 68 A, making it suitable for demanding multi-axis machinery, factory automation systems, and precision motion tasks. Equipped with high-speed SSCNET III/H optical communication capability, the MR-J4-15KA-RJ ensures synchronized real-time multi-axis motion and rapid network communication with compatible controllers. The unit features an IP20 degree of protection and is rated to function reliably in ambient operating temperatures ranging from 0 to +55 degrees Celsius. Additionally designated as equivalent to MRJ411KB, this servo amplifier integrates seamlessly into industrial drive systems requiring dependable torque and speed control.
