Mitsubishi MR-JE-20A MELSERVO-JE 200W AC Servo Amplifier 200W 1‑Phase/3‑Phase 200‑240V

Mitsubishi Electric MELSERVO‑JE MR‑JE‑20A is a general‑purpose AC servo amplifier for precise motion control in industrial automation. Rated output 200W (0.2kW) at 200‑240V AC, single‑phase or three‑phase input. Supports position, speed, and torque control modes with high‑resolution 17‑bit absolute encoder feedback (131,072 pulses/revolution). Built‑in dynamic brake, 2.0 kHz speed frequency response, and one‑touch tuning for simplified setup. Advanced vibration suppression control automatically detects and suppresses mechanical resonance between 10‑500Hz. Designed for small‑to‑mid‑size precision automation, pick‑and‑place, packaging, conveyor positioning, and laboratory automation equipment.

Applications:

• Automated assembly systems and pick‑and‑place stations

• Packaging machinery, labeling machines, and form‑fill‑seal equipment

• Conveyor positioning and material handling systems

• Laboratory automation and precision instruments

• Small CNC routers, engraving machines, and X‑Y tables

• Textile machinery and printing equipment

• Food processing machinery and pharmaceutical packaging
