The Caterpillar VR6 (309-1019) is an automatic voltage regulator for the generator excitation side of a vessel’s electrical power plant. It senses alternator output and adjusts field current so that terminal voltage holds steady as electrical load changes. The unit accepts shunt excited power at 180-280 V AC or PMG excitation at 63-105 V AC, with a CT input for 1 or 5 A AC and an accessory input of +/- 3 V DC. Its field output is rated 65 V DC at 12 A DC. This regulator is supplied in used condition.
