Description
The VR6 Voltage Regulator is contained in an encapsulated plastic case. The regulator controls the DC exciter fifi eld power of conventional, 50 or 60 Hz brushless genera tors.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 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.
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.
