2.Applications
§ standard : for LSA 46.2, 47.2, 49.1 and LSA 50.2 alternators.
§ optional : for LSA 42.2, 43.2, 44.2. alternators Adapted to the SHUNT, AREP or PMG excitation systems.
3.R450 Main characteristics
§ Voltage regulation +/- 0.5% at steady state and constant speed.
§ Control by transistor means that the regulation quality is independant of applied load.
§ Phase to phase voltage sensing.
§ Suitable for high levels of vibration and harsh environments.
§ Integrated "LAM" and " auto adaptative LAM" system to cope with load impacts applied to the engine
§ AREP or PMG excitation with normal or fast response.
§ Single or three phase voltage sensing with optional module.
§ Rotating switch facilitating selection.
