MR-J2S-200B 2kW SSCNET Servo Amplifier MELSERVO J2S | Mitsubishi

The Original New Mitsubishi MR-J2S-200B is a 2 kW (2000 W) AC servo amplifier from the MELSERVO J2-Super series, designed for high-performance motion control in industrial automation systems. It operates on a 200–230 V AC single-phase or three-phase supply and communicates exclusively via the SSCNET high-speed serial network interface, receiving position, speed, and torque commands from compatible Mitsubishi motion controllers. The amplifier features a built-in dynamic brake and forced ventilation cooling, delivering reliable performance for material handling systems, industrial robots, and X-Y working tables. This product is discontinued and available as a spare part for maintaining existing MELSERVO J2S installations. For new designs, the recommended replacement is the MELSERVO-J4 series MR-J4-200B-RJ020 with conversion modules.
