     This replacement voltage regulator for R 449 is a shunt type AVR. 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 synchronization.

    The output power is 7amps @ 63VDC under normal conditions and 15A for 10s under overload conditions.

    The power can be supplied:
    - using 2 independent auxiliary windings integrated in the alternator stator (AREP excitation)
    - using a single or 3-phase power VT
    - using a single or 3-phase PMG.

    Note: The single or 3-phase input voltage must not exceed 240V AC.
