ABB ZGAB-592 Brake Chopper Adapter Board – ACS880 Braking Unit – Tested

Product Overview

Original ABB ZGAB-592 brake chopper adapter board for ACS880 series drives. Serves as the core energy dissipation unit in the drive’s regenerative braking system, controlling the braking chopper to transfer excess energy from the DC link to an external braking resistor when required. Used in ACS880 R8/R9 frame drives.
