R450 is analog Automatic Voltage Regulator with transistors.
for LSA 46.2, 47.2, 49.1 and LSA 50.2 alternators
Leroy Somer
servo voltage regulator

The R450 is analog Automatic Voltage Regulator with transistors.


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.

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.

The R 450 is compatible with other modules offered by Leroy-Somer enabling additional functions.
