Product Description

​The Mitsubishi MR-J2S-200B is a 2.0 kW AC servo amplifier from the MELSERVO J2-Super series, engineered for high-performance motion control in industrial automation systems. It operates on a 3-phase 200–230V AC input and utilizes sine-wave PWM control for precise motor control. Equipped with built-in dynamic braking and a high-resolution 17-bit encoder, it supports SSCNET III/H high-speed serial communication with a cycle time of 0.888 ms, enabling seamless integration with Mitsubishi's motion controllers. This servo amplifier is ideal for applications requiring accurate positioning and high-speed response, such as robotics, CNC machinery, and semiconductor equipment.​
