Mitsubishi Electric MR-J2S-20CP Servo Amplifier

The Mitsubishi Electric MR-J2S-20CP servo amplifier from the MELSERVO J2-Super series provides built-in positioning control and dynamic braking, allowing direct control of servo motors without a separate motion controller. Designed for industrial automation, it is commonly used in CNC machines, packaging systems, and automated production equipment. Key specs include rated output 0.2 kW (200 W); input voltage 200–230 VAC (1- or 3-phase) at 50/60 Hz; control function built-in positioning (pulse-train control); built-in dynamic brake; control modes position, speed, and torque; compatible motors HC-KFS, HC-MFS, HC-SFS, HC-RFS series; encoder-based closed-loop feedback; cooling via natural or forced air depending on panel; mounting panel mount in control cabinets; operating temperature 0–55°C; protection features overcurrent, overvoltage, overload, overheating. Status: Discontinued / legacy module. Common replacements: MR-J3-20A, MR-J4-20A, MR-JE-20A.
