Specification

The Mitsubishi Servo Drive MR-J3-350A is a 3.5 kW servo amplifier engineered for high-precision industrial automation. Part of the renowned MR-J3 series, this model delivers exceptional performance in position, speed, and torque control modes, making it suitable for applications like CNC machinery, robotics, and packaging equipment. With a 3-phase 200 to 230 VAC power input and a permissible voltage fluctuation of 170 to 253 VAC, it ensures stable operation under varying line conditions. The drive features a sine-wave PWM control system, a built-in dynamic brake, and comprehensive safety protections including overcurrent, overload, and encoder fault detection. Its fan-cooled open structure (IP00) supports reliable operation in ambient temperatures from 0 to 55°C, while the high-resolution encoder feedback (262144 p/rev) guarantees precise positioning. The MR-J3-350A is a robust, 100% original solution for demanding motion control tasks.
