The MR-J3-70AS042 module functions as a servo amplifier in Mitsubishi's MELSERVO MR-J3 product line. The main circuit requires a 3-phase power supply, accepting an input voltage range of 200 to 230VAC, with a frequency of either 50 or 60 Hz. This amplifier can endure fluctuations in the input voltage ranging from 170 to 253VAC. It has a permissible frequency fluctuation tolerance of +/-5%.

This unit features a control circuit powered by a single-phase input of 200 to 230VAC. It draws 0.2A of rated current and consumes a total of 30W. The amplifier operates under a sine-wave PWM control and current control system, ensuring smooth and precise motor management.

The output specifications include a 3-phase rated output voltage of 170VAC and a current rating of 5.8A. Furthermore, it houses a built-in dynamic brake that enhances performance during operation.

Weighing in at 1.4 kg, the servo amplifier has a structure designed for force cooling and is classified with an IP00 rating, denoting an open-enclosure type without specific ingress protection. The interface power supply operates at 24VDC, providing the necessary power for effective control and operation.
