Product Overview

The ABB 3BHE026284R0102, model UAD215A102, is a high-performance panel controller and converter board specifically engineered for the UNITROL series of excitation systems. This unit functions as a central command interface within the power electronics assembly, bridging the gap between supervisory control logic and the physical power conversion stage. Its primary role is to manage the user interface and local control parameters for generator excitation, ensuring that voltage regulation and reactive power management are executed with high-speed precision. Designed for integration into Distributed Control Systems (DCS), the UAD215A102 provides the deterministic data processing required to maintain grid stability and synchronized generator performance.
