Compact voltage regulator module designed for stable generator excitation and consistent output under changing load and environmental conditions. Key benefits Precise voltage control: Maintains output within plus or minus 1 percent, keeping generator voltage steady during sudden load changes and preventing downstream equipment from seeing voltage swings. Flexible installation: AC input selectable from 180 to 260 V via DIP switches, so the unit can be configured for a range of generator AC systems without needing custom wiring. Strong excitation capability: Delivers up to 7 A for continuous excitation and supports shortduration peaks, providing reliable field current when the generator demands rapid response. Adaptive under low frequency: Builtin frequency sensing automatically adjusts output during low frequency conditions, improving performance during startup, heavy load, or engine speed variations. Stable across temperatures: Low temperature drift preserves voltage accuracy when ambient conditions change, reducing the need for manual adjustment and maintenance. How it solves common problems Eliminates voltage fluctuations that can damage sensitive electronics or cause nuisance trips by keeping output tightly regulated. Simplifies system setup with DIPswitch input range selection, reducing installation time and configuration errors. Provides sufficient excitation current for steady operation and transient demands, improving generator response to load shifts. Compensates for low engine speed or weak prime mover frequency, maintaining excitation and generator stability until normal conditions .
