ABB Unitrol 6000 UNS5907AV5082 | 3ADT218440R0003 Excitation System Module

Product Description

ABB Unitrol 6000 Excitation System spare module, Part No.: UNS5907AV5082, Order No.: 3ADT218440R0003. It is a core processing & interface board for Unitrol 6000 excitation regulator system built on AC800PEC hardware platform, performing signal acquisition, regulation calculation, logic processing and data communication for synchronous generator excitation controlABB. This board supports AVR automatic voltage regulation, field‑current regulation and PSS power system stabilizer calculation. It supports single‑channel or redundant dual‑channel excitation control for both static excitation and brushless indirect excitation systems. It provides event logging, disturbance recording and internal diagnostic monitoring. It is original OEM replacement spare part for thermal, hydro and gas‑fired power plant Unitrol 6000 excitation units, compatible with ABB 800xA control system, and supports commissioning software for parameter setting and post‑fault analysisABB Group.
