Specification

The Mitsubishi Servo Drive MR-J3-20B is a state-of-the-art 200W servo amplifier engineered for demanding industrial automation applications. This model, part of the renowned MR-J3 series, delivers exceptional precision and reliability through its sine-wave PWM control and current control system. With a built-in dynamic brake and robust safety mechanisms, the MR-J3-20B ensures stable operation under varying loads and environmental conditions. Its versatile control modes—position, speed, and torque—make it suitable for a wide range of machinery, from CNC machines to packaging equipment. The drive supports high-resolution encoder feedback (262144 p/rev) and a maximum input pulse frequency of 1Mpps (differential receiver), enabling precise positioning and speed regulation. Designed for easy integration, it operates on 3-phase 200-230VAC or 1-phase 200-230VAC power, with permissible voltage fluctuation of 170-253VAC. The self-cooling IP00 enclosure ensures reliable performance in indoor environments without corrosive gases or dust. This unit is 100% original and new, backed by Mitsubishi Electric's quality standards, and available for immediate shipment.
