Key Features
Description

The AVC63-7 AVR Voltage Regulator is an encapsulated unit contained in a plastic case. The regulator controls the dc exciter field power of conventional, 50 or 60 Hz brushless generators that have a 63 Vdc exciter field to regulate the generator output voltage.

SENSING VOLTAGE

170 to 264 Vac, single-phase, 50/60 Hz

TEMPERATURE OPERATING

–40 to 60°C (–40 to 140°F) –65 to 85°C (–85 to 185°F)

The AVC63-7 AVR Voltage Regulator is an encapsulated unit contained in a plastic case. The regulator controls the dc exciter field power of conventional, 50 or 60 Hz brushless generators that have a 63 Vdc exciter field to regulate the generator output voltage.

Regulation is provided by sensing the generator output voltage, converting it to a dc signal and comparing the signal to a reference voltage signal. An error signal is developed and used to control the dc field power in order to maintain a constant generator output.
