Mitsubishi Electric MR-J2S-350A Servo Amplifier

The Mitsubishi Electric MR‑J2S‑350A is a 16 A AC servo amplifier drive that powers Mitsubishi AC servo motors with closed‑loop encoder feedback to deliver precise speed, torque, and position control in CNC machines, robotic systems, automated conveyors, and other motion‑control applications. It accepts 200–230 VAC, 3‑phase power at 50/60 Hz and uses pulse-train input with encoder feedback, with a panel‑mount enclosure and built‑in cooling fan. Protection features include overcurrent, overvoltage, overheating, and short‑circuit protection; operating temperature 0°C to 50°C and storage from −20°C to 65°C. Interface options include Pulse/Direction with optional fieldbus modules, LED run/alarm indicators, and compatibility with Mitsubishi AC servo motors; common replacement is MR‑J2S‑350B.
