1.1 - SHUNT excitation system
The SHUNT excitation alternator is auto-
excited with a
R 250
voltage regulator.
The regulator controls the excitation current
according to the alternator’s output voltage.
With a very simple conception, the SHUNT
excitation alternator does not have a short
circuit capacity.
