Product Description

ABB KUC720AE01 3BHB003431R0101 Excitation Control Board

ACS1000 Series - Core Control Component for Medium-Voltage Inverter Excitation Systems

1. Product Overview

The ABB KUC720AE01 3BHB003431R0101 is a dedicated excitation control board designed for ABB ACS1000 medium-voltage (MV) inverter systems, acting as the core component to regulate and control the excitation current of power semiconductor devices (IGBTs) in MV drives. It integrates precise current regulation, real-time status monitoring, and fault protection functions, ensuring stable and efficient operation of the inverter's excitation system. With compatibility for multiple communication protocols and seamless integration with ACS1000 control units, the board provides reliable excitation control for industries such as power generation, oil & gas, mining, and heavy industry where MV drive stability is critical.
