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.
