SHALUO Automatic Voltage regulator china avr R230
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.
