Mitsubishi Electric MR-J2S-40A Servo Drive Module

The MR-J2S-40A is a 0.4 kW class digital AC servo amplifier in Mitsubishi Electric's MELSERVO-J2-Super family, designed to drive compact servo motors in general automation. As a 40A power-class MR-J2S model, it accepts standard 200–230 VAC input and provides precise position, velocity, and torque control for servo systems. Commonly paired with 0.4 kW motors such as HC-KFS43, HC-MFS43, and HC-UFS43, the MR-J2S-40A integrates with Mitsubishi automation ecosystems and supports MR-J2S control interfaces. Typical applications include CNC, packaging, electronics assembly, and general automation machinery where reliable, precise motion is required.
