The CAT VR6 (365-2076) is a permanent magnet voltage regulator used in the automatic voltage regulator system of a generator set. It controls the excitation current fed to the alternator field so that output voltage holds at the set level as electrical load changes. The unit accepts either shunt excitation from the generator output or power from a permanent magnet generator. It reads generator voltage through a dedicated sensing input and also takes a current transformer input. This regulator is supplied in used condition.
