Product Details

ABB UAA326A02 HIEE300024R2 is an excitation control board used for ABB UNITROL generator excitation systems. The excitation control board undertakes real-time signal processing and control logic calculation for generator voltage regulation. This ABB UAA326A02 board collects voltage and current signals from the generator, adjusts the excitation output to stabilize the generator terminal voltage, and provides overexcitation and underexcitation protection functions. The generator control board adopts high-reliability circuit design, with strong anti-electromagnetic interference ability to adapt to harsh working conditions in power plants. It supports real-time status monitoring and fault diagnosis, which can quickly alarm and record abnormal working conditions. Widely applied in power generation, hydropower and thermal power units, it is a key spare part for the maintenance and renovation of generator excitation equipment. The board adopts rack plug-in installation, which is convenient for disassembly, maintenance and spare parts replacement.
