Mitsubishi MR-BAT6V1SET Servo Amplifier Battery Set

Product Overview

The Mitsubishi MR-BAT6V1SET is a servo amplifier backup battery set designed for Mitsubishi MELSERVO AC Servo Amplifier systems. It is used to maintain the absolute position data of servo motors when the main power supply is turned off, preventing the loss of encoder position information.

This product is an accessory battery, not a servo amplifier itself. It is mainly used with Mitsubishi MR-J4, MR-J5, MR-JE and compatible servo amplifier series.
