The Mitsubishi Electric MR-J4-500B-RJ is a 5 kW digital AC servo amplifier engineered for high-speed, high-precision motion control on SSCNET III/H networks (RJ type). Built for demanding OEM and machine-builder applications, it delivers responsive positioning and deterministic synchronization for packaging, printing, CNC, and automated assembly lines.
As a single-axis drive in the MELSERVO-J4 platform, the MR-J4-500B-RJ pairs with Mitsubishi servo motors to provide fast control loops, advanced vibration suppression, and autotuning for stable performance. The unit accepts 200 to 240 VAC (230 V class) three-phase supply, integrates a dynamic brake, and implements Safe Torque Off (STO) in accordance with IEC/EN 61800-5-2. An IP20 enclosure, compact 105 x 250 x 200 mm footprint, and SSCNET III/H RJ cabling (RJ45) streamline panel layout and wiring, while global approvals (CE, UL/cUL, EAC, UKCA) support international deployments; ambient operation is specified from 0 to +55°C.
Engineered for reliability and straightforward integration, this amplifier helps shorten commissioning and maintain throughput across multi-axis systems, and it further protects your investment with a 1-year warranty integrated into our professional supply and support offering.
