Mitsubishi Electric MR-J2S-100CP Servo Amplifier

The Mitsubishi Electric MR-J2S-100CP is an AC servo amplifier from the MELSERVO J2-Super series with built-in positioning capability, enabling direct control of servo motors without an external motion controller. Rated at 1.0 kW, it accepts 200–230 VAC input at 50/60 Hz and provides encoder-based closed-loop control with a built-in positioning function (pulse train control) and a built-in dynamic brake, supporting position, speed, and torque control. Designed for panel-mount in control cabinets, it uses forced-air cooling and operates from 0°C to 55°C with protections for overcurrent, overvoltage, overload, and overheating. Compatible motors include the HC-KFS, HC-MFS, HC-SFS, and HC-RFS series, and common replacements are Mitsubishi MR-J3-100A, MR-J4-100A, and MR-JE-100A; this module is listed as discontinued/legacy.
