Description
Product Introduction
The Basler Electric SR8A-2B15B3A Static Voltage Regulator is an automatic voltage regulator (AVR) designed to control excitation in synchronous generator systems. By regulating generator field current, it helps maintain stable output voltage as electrical load conditions change.
The SR8A series is used in industrial and marine power-generation applications, including generator control panels and excitation systems. Its functions can include voltage sensing and regulation, reactive droop or cross-current compensation for parallel generator operation, and underfrequency protection, depending on the specific model configuration.
This regulator is intended for maintenance and replacement applications where the original generator system specifies the same SR8A model and option configuration. Confirm the complete model number, sensing input, excitation requirements, wiring arrangement, and installed generator specifications before replacement.
