Mitsubishi MR-J4-70A Servo Drive – 0.75kW, 200V

The Mitsubishi MR-J4-70A is a versatile digital AC servo amplifier from the advanced MELSERVO J4 series, engineered for fast and precise control of motion systems in compact automation setups. Designed for both single-phase and three-phase 200–240V AC input, this unit supports a 0.75 kW motor output at a rated current of 5.8 A. Integrated RS-422/RS-485 communication makes it a reliable solution for basic motion networks and standalone controls. Equipped with Safe Torque Off (STO) safety, IP20 open-type protection, and forced ventilation cooling, the MR-J4-70A is ideal for small conveyors, pick-and-place arms, and general-purpose servo applications in confined panel spaces.
