Mitsubishi Electric MR-J2S-10B Servo Amplifier

The Mitsubishi Electric MR-J2S-10B is a 0.1–0.2 kW AC servo driver amplifier in the MELSERVO-J2-Super family, designed for precise, high-speed motor control in CNC machines, robotics, and automated production equipment. It accepts 200–230 V AC (single-phase or three-phase), uses sinusoidal PWM/current control, and supports SSCNET high-speed communication for reliable, synchronized motion. Key specs include a speed frequency response of ≥550 Hz, built-in dynamic brake, self-cooling operation, operating temperature 0 to 55°C, and protection functions for overcurrent, overload, overvoltage, encoder fault, and overspeed. Mounting is panel-mount for control cabinet installation, and common replacements include MR-J2S-10A Servo Amplifier, MR-JE-10B Servo Amplifier, and MR-J4-10B Servo Amplifier.
