The R 449 voltage regulator is of a shunt type. It is designed
to fit as standard on A50 to A 54 alternators. It can be supplied
with power either by a power VT, or by the AREP field
excitation system, or by a single-phase or 3-phase PMG.
Using the R 726 external module, the regulator can control
the power factor (2F) and can match the alternator voltage to
the mains voltage (3F) prior to synchronisation.
