Product Details

ABB UFC911B110 3BHE037864R0110 is a high-performance controller processing unit for ABB AC800PEC and UNITROL generator excitation systems. The controller processing unit executes high-speed calculation algorithms, collects generator voltage and current signals in real time, and completes closed-loop excitation regulation and system protection logic. This ABB UFC911B110 unit adopts high-speed optical fiber communication interfaces to exchange data with I/O boards and peripheral modules, ensuring fast response of excitation control. The AC800PEC control unit integrates multiple protection functions including overexcitation, underexcitation and loss-of-field protection to protect generator equipment. It has built-in self-diagnostic function to continuously monitor hardware running status and report fault information timely. It features excellent anti-electromagnetic interference performance to maintain stable operation in harsh power plant environments. Widely used in thermal power and hydropower generator excitation cabinets, it is essential spare part for excitation system maintenance and upgrade. It adopts rack plug-in structure for simple installation and quick on-site replacement.
