INQUIRY

VR6 AVR are contained in an encapsulated plastic case, and regulator controls the DC exciter field power of

conventional, 50 or60 HZ brushless generators. Regulation is provided by sensing the generator output voltage,

converting it to a DC signal and comparing the signal to a reference voltage signal. Which 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.

The regulator includes frequency compensation with selectable slope,inverse time over-excitation shutdown, solid-state build-up circuitry,single-phase or three-phase voltage sensing, single-phase or threephase shunt, or permanent magnet power input, and parallel droop compensation, and an accessory

input. The accessory input provides compatibility with accessories such as a var/power factor controller.
