Mitsubishi Electric MR-J2S-100A Servo Amplifier

The Mitsubishi Electric MR-J2S-100A is a 1 kW AC servo drive amplifier designed to power Mitsubishi AC servo motors in CNC machines, robotics, and automated production lines. It delivers precise speed, torque, and position control via pulse-train input with closed-loop encoder feedback, enabling repeatable motion in high-demand applications. Operating from 200–230 VAC, 3-phase power at 50/60 Hz, it provides about 10 A of continuous output current, and features a built-in cooling fan and panel-mount enclosure for compact installation. The drive uses a Pulse/Direction interface with optional fieldbus modules and includes LED run/alarm indicators for straightforward status monitoring, making it compatible with the Mitsubishi AC servo series and common automation architectures. For replacements or upgrades, MR-J2S-100B is a commonly cited alternative.>
