1. VR6
VR6 controls the DC exciter field power of conventional, 50 or 60 Hz brushless genera tors. The regulator(VR6) 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.
