Mitsubishi MR-JE-100A MELSERVO-JE 1kW General-Purpose AC Servo Amplifier

Mitsubishi Electric MELSERVO-JE MR-JE-100A is a general-purpose AC servo amplifier for high-precision motion control in industrial automation and OEM systems. Rated output 1 kW (1,000 W) at 200-240 V AC, single-phase or three-phase input. Supports position, speed, and torque control modes with 17‑bit absolute encoder feedback (131,072 pulses/revolution). Built‑in dynamic brake, built‑in regenerative resistor, and advanced one‑touch auto‑tuning simplify setup and reduce commissioning time. 4 Mpps maximum input pulse frequency (differential receiver).
