Adopting fully sealed packaging design, EA63-7D can be safely installed and operated in various severe working environments. Its solid and robust mechanical structure effectively lowers failure rates and cuts costly maintenance expenses for generator equipment.

This AVR supports 7A continuous excitation current output for exciter. The voltage regulation accuracy from no-load to full load is controlled within ±0.25%. Equipped with rapid response and frequency compensation functions, it realizes instantaneous voltage compensation under variable load conditions.

With integrated parallel control circuit and simple parameter setup, the unit delivers excellent reactive load distribution performance for quick commissioning and multi-generator parallel operation.

Constant Automatic Voltage Control (AVC) runs continuously throughout the entire operating temperature range. Voltage regulation performance remains consistent without rating reduction or performance degradation, eliminating voltage fluctuation troubles caused by temperature changes.

It is equipped with V/Hz limitation, over-excitation shutdown and external voltage adjustment input. As a universal voltage regulator, EA63-7D fits most generator models and helps reduce your spare parts inventory pressure.

Thanks to integrated circuit design, the whole unit features small overall dimensions, which can be easily installed inside almost all standard generator terminal boxes with simple layout.
