ABB PPD103B101 3BHE020455R0101 Excitation Power Drive Board

Product Description

ABB PPD103B101 (Part No:3BHE020455R0101) is a power control board (PPD power drive board) for ABB UNITROL excitation control system, the core board of synchronous generator excitation regulation system. This board receives control signals from the main excitation regulator and triggers the thyristors in power circuit to continuously adjust generator excitation current. It integrates pulse amplification, fault diagnosis, signal acquisition and status feedback functions. Designed for high noise immunity and reliability, it is widely used in high-power excitation systems of power plants and serves as common spare part for excitation cabinets of hydro and thermal power generating units.
