Available. The Mitsubishi MR-J3-70A is a high-performance digital AC servo amplifier from the MELSERVO-J3 series, designed to provide precise motion control in industrial automation applications. Operating on a 3-phase AC supply of 200 to 230 V at 50/60 Hz, it delivers a rated output of 0.75 kW (750 W) with a current rating of 5.8 A. The amplifier utilizes sine-wave PWM control and current control systems to ensure smooth and accurate servo motor operation. It features a built-in dynamic brake and regenerative resistor, enhancing system stability and safety. The MR-J3-70A supports a wide range of servo motors, including the HF-KP73 and HF-MP73 series, and offers a maximum input pulse frequency of 1 Mpps when using a differential receiver. Its compact design measures 60 mm in width, 168 mm in height, and 185 mm in depth, with a weight of approximately 1.4 kg. This servo amplifier is suitable for applications requiring high-speed positioning and low-speed stability, such as robotics, CNC machinery, and automated assembly lines.
