Available. The Mitsubishi MR-J3-20B is a 200 W (0.2 kW) servo amplifier from the MELSERVO-J3 series, designed for precise motion control in industrial automation applications. Operating on a 200–240 VAC single-phase or three-phase power supply at 50/60 Hz, it delivers continuous output current of 1.5 A, suitable for driving Mitsubishi HC-KFS23 and HC-MFS23 series 200 W servo motors. The amplifier utilizes the SSCNET III optical fiber network interface, enabling high-speed communication and synchronization in multi-axis systems. Its compact design, with a width of 40 mm, allows for efficient use of panel space in dense installations. The MR-J3-20B features a self-cooling, open (IP00) structure, ensuring reliable performance in various industrial environments. Key protective functions include overcurrent protection, regenerative overvoltage protection, overload protection (electronic thermal), servo motor overheat protection, and more, safeguarding both the amplifier and connected equipment. This servo amplifier is ideal for applications requiring precise and reliable motion control, such as robotics, CNC machinery, and automated assembly lines.
