he K65-12B Voltage Regulators are contained in an encapsulated plastic case. The regulator controls the DC exciter fi eld power of conventional, 50 or 60 Hz brushless genera tors.
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 fi eld 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.
