- Type： R449
- Product Summary：
DESCRIPTION: The R449 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.
