Product Introduction

The ABB UAD149 3BHE014135R0011 UAD149A00-0-11 is an exciter control board used in ABB generator excitation systems. It undertakes signal sampling, regulation calculation and pulse output functions for generator excitation control. It collects voltage and current signals, adjusts excitation output to stabilize generator terminal voltage, and supports fault monitoring and protection functions. Widely applied in power plant generator excitation control systems.

Content Details

UAD149A00-0-11 is installed inside the excitation cabinet, cooperating with power units to realize closed-loop excitation regulation. It processes multi-channel analog and digital signals, triggers power components according to control algorithms. Built-in circuit protection prevents damage caused by overvoltage and overcurrent. LED indicators display board operating state and fault codes for convenient on-site inspection and maintenance. Industrial high-reliability PCB design can adapt to vibration and electromagnetic interference in power station environments. It is an important spare part for generator excitation system overhaul and retrofit. Each board passes full function test and thermal aging test before shipment.
