Product Description

The Mitsubishi MR-J3-20B1 is a 200W AC servo amplifier from the MELSERVO-J3 series, designed for high-precision motion control in industrial automation systems. It operates with a single-phase 100–120V AC input and provides a three-phase 170V AC output, delivering a rated current of 1.5A. This model utilizes sine wave PWM control and current control methods, ensuring smooth and accurate motor performance. The MR-J3-20B1 is equipped with built-in dynamic braking and regenerative resistors, enhancing system stability and safety. It features comprehensive protection mechanisms, including overcurrent, regeneration overvoltage, overload, motor overheat, encoder fault, regeneration fault, undervoltage, sudden power outage, overspeed, and excessive error protections. Additionally, it supports SSCNET III/H high-speed serial communication, facilitating seamless integration with Mitsubishi's advanced control systems.
