Product description:
The K65－12B and K125-l0B Voltage Regulators are contained in an encapsulated plastic case. The regulator controls the DC exciter field power of conventional, 50 or 60 Hz brusliless
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. 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 three-phase slnint, 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.
