ABB KUC711AE 3BHB004661R0001

1. Product NameHigh-performance Excitation Controller Module
2. Product DescriptionThe ABB KUC711AE 3BHB004661R0001 is a dedicated excitation control module belonging to ABB’s static and indirect excitation system portfolio, designed specifically for synchronous generators in hydropower, combined-cycle, and pumped storage power plants. Its core function is to precisely regulate the generator’s excitation current and voltage, ensuring stable output voltage and frequency of the generator, and maintaining the power system’s voltage stability and reactive power balance.
3. The module integrates high-precision signal acquisition, closed-loop control algorithms, and multiple protection functions, supporting both manual and automatic excitation control modes. It features industrial-grade components and a robust circuit design, with built-in overcurrent, overvoltage, overheating, and loss-of-field protection mechanisms to safeguard the generator and excitation system from faults. Equipped with flexible communication interfaces, it can seamlessly integrate with DCS (Distributed Control System) and SCADA systems for remote monitoring, parameter adjustment, and fault diagnosis. With its compact structure and DIN rail mounting design, the module is easy to install and maintain, and is suitable for harsh industrial environments with strong electromagnetic interference and wide temperature fluctuations. It is widely used in power generation, marine, oil and gas, and port crane fields.
