Mitsubishi MR-J4-350B-EB AC Servo Amplifier for MELSERVO-J4 Series

The Mitsubishi MR-J4-350B-EB is an AC motion servo drive and amplifier developed for high-precision industrial automation within the MELSERVO-J4 series. Operating with a 200 V class power supply rated for 200 to 240 V AC on single-phase or three-phase line inputs, this drive provides a rated output power of 3.5 kW (3500 W) and a rated current of 17 A. It utilizes high-speed SSCNET III/H optical communication for reliable motion networking, low latency, and deterministic multi-axis synchronization with motion controllers. Engineered for demanding manufacturing processes, the MR-J4-350B-EB incorporates a built-in dynamic brake and an integrated braking resistor to handle regenerative energy and enable safe, rapid stopping. The drive features an IP20 degree of protection and is rated to operate reliably within an ambient temperature range of 0 to +55 degrees Celsius. Compatible with MR-J4 motion architectures and functionally equivalent to the MRJ4350B design, this amplifier is ideally suited for packaging systems, material handling machines, machine tooling, and multi-axis automated assembly lines.
