Specification

The Mitsubishi Servo Drive MR-J3-350B is a 3.5 kW AC servo amplifier designed to deliver exceptional performance in high-speed, high-precision automation systems. Part of the renowned MR-J3 series, this unit features advanced sine-wave PWM current control, ensuring minimal torque ripple and superior energy efficiency. With a wide input voltage range (3-phase 200-230 VAC, 50/60 Hz) and a permissible fluctuation of 170-253 VAC, it is built for stable operation in industrial environments. The drive integrates a built-in regenerative resistor (130 W) and dynamic brake, while supporting multiple control modes—position, speed, and torque—via electronic gearing and analog inputs. Its safety features include overcurrent, overvoltage, overload, encoder fault, and undervoltage protection, making it a reliable choice for CNC machinery, robotics, and packaging lines.
