MR-J2S-200A 2kW Universal Interface Servo Amplifier | Mitsubishi

The Original New Mitsubishi MR-J2S-200A 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 supports position, speed, and torque control modes with a speed frequency response of 550 Hz or higher. The amplifier features a built-in dynamic brake for rapid deceleration and is compatible with HC-SFS and HC-LFS series servo motors with 17-bit (131,072 ppr) encoder feedback. This product is discontinued and available as a spare part for maintaining existing MELSERVO J2S installations.
