AVC63-7
VOLTAGE REGULATOR
Using enhanced technology, the AVC63-7 half wave voltage regulator is
designed for use on 50/60 Hz brushless generators. This encapsulated
regulator is small in size, ruggedly constructed, and incorporates solid
state technology with frequency compensation, automatic voltage build-
up, and parallel droop as standard.
