Output voltage regulation should be carried out at
nominal revolving speed (3000 rpm for 2 poles

The alternators are calibrated to deliver the nominal
voltage.To correct the output voltage of the alternator
it is necessary to act on the potentiometer located on
the regulator.Voltage increases with a clockwise
rotation of the potentiometer.

Protections
0,19 14,50 1,03
The electronic regulator acts also as protection against
overloads on exciting windings of the alternator when
0,19 14,50 1,03
functioning at a frequency lower than the nominal one,
in case of overload or loads with low power factor. A
0,14 14,95 1,06
first protection checks the frequency of the output
0,14 14,95 1,06
voltage and de-excites the alternator when it is lower
than 45 Hz (55 Hz when nominal frequency is 60 Hz).
A second protection checks the voltage at the ends
of the exciter stator and de-excites the alternator when
this voltage is higher than the intervention level set
0,48 21,20 1,50
with the S potentiometer.The intervention level can
0,51 21,25 1,51
be increased with an anti-clockwise rotation of the
potentiometer.

also operate at 60 Hz connecting terminals 6 and 8 of
regulator terminal board with a bridge.
