SDMO AVR 330410345 Voltage Regulator

FG Wilson AVR 922-197 Voltage Regulator

Olympian AVR 922-197 Voltage Regulator

The alternator with Shunt excitation is self- excited with an Leroy Somer R230 voltage regulator.

The regulator monitors the exciter excitation current as a function of the alternator output voltage. Very simple in design, the alternator with shunt excitation has no sustaining short-circuit capacity.
