Automatic Voltage Regulator UNS 0119A-Z,V1 3BHE030579R0207 ABB

Description

TheABB UNS0119A-Z,V1(Part No.3BHE030579R0207) is a digitalAutomatic Voltage Regulator (AVR)designed for high-performancesynchronous generator excitation systems. It ensures stable generator terminal voltage under rapidly changing load conditions, supporting bothgrid-parallelandisland-modeoperation. Built as part of theUNITROLfamily, this controller delivers fast regulation, enhanced monitoring, and advanced protection features to maximize generator reliability and operational safety. Itsrugged enclosure,wide temperature tolerance, andflexible mounting optionsmake it suitable for harsh environments such as power stations, offshore platforms, and industrial facilities. For example, in a hydroelectric power plant, the UNS0119A-Z,V1 maintains precise voltage regulation during transient events like load rejection or grid disturbances.
