ABB GDB021BE01 HIEE300766R0001 Gate Driver Control Board for Generator Excitation System

Product Description

GDB021BE01 (HIEE300766R0001) is a Eurocard‑format plug‑in gate driver control board for ABB generator excitation control system. It receives firing pulse commands

from main excitation controller, generates, amplifies and distributes trigger gate signals for thyristor power rectifier bridges. It executes pulse‑amplitude adjustment, signal isolation,

pulse monitoring and fault detection functions. It collects feedback status of power rectifier unit and sends fault alarm back to main controller. Widely deployed in thermal power,

hydropower plant generator excitation cabinets.
