MR-J3-70A
The Mitsubishi MR-J3-70A is a servo amplifier designed to provide efficient control. With an output-rated voltage of 3-phase 170VAC and a rated current of 5.8A, it offers robust performance for various applications. The main circuit power supply operates at 3-phase or 1-phase 200 to 230VAC, 50/60Hz, with a rated current of 3.8A. The control power supply operates at 1-phase 200 to 230VAC, 50/60Hz, with a rated current of 0.2A. It consumes 30W of power and features a 24VDC interface power supply. The amplifier uses a sine-wave PWM control and a current control system for precise operation. Designed for natural cooling in an open structure (IP rating: IP00), it weighs 1 kg (2.21 lbs), making it suitable for diverse industrial applications.
