ABB DSQC 655 3HAC025562-001 Capacitor Unit

Product Overview

The ABB DSQC 655 (3HAC025562-001) is a high-performance Capacitor Unit integrated into the IRC5 robot controller's drive system. Its primary role is to serve as an energy reservoir for the DC common bus that powers the robot's motor segments. By storing and releasing electrical energy instantaneously, the DSQC 655 smooths out voltage ripples and provides the peak current necessary during rapid acceleration or heavy lifting, preventing "DC Link Voltage Low" errors and protecting the drive electronics from power surges.
