Leroy-Somer Alternator AVR R450

1 - GENERAL INFORMATION of Leroy-Somer Alternator AVR R450 1.1 - Description The R450 AVR is supplied in a casing designed to be mounted on a panel with dampers. - Operating temperature: - 30°C to + 65°C. - Storage temperature: - 55°C to + 85°C. - Shocks on the base: 9 g depending on the 3 axes. - Vibrations: less than 10 Hz, 2 mm half-peak amplitude 10 Hz to 100 Hz: 100 mm/s, above 100 Hz: 8 g. The AVR is IP00, it must be incorporated in an environment which ensures it a IP20 protection. 1.2 - Characteristic The connection is realised by “Faston” connectors and the voltage sensing is single - phase. 2 - POWER SUPPLY Both the SHUNT/AREP & PMG excitation systems are controlled by the AVR. 2.1 - AREP excitation system With AREP excitation, the electronic AVR is powered by two auxiliary windings which are independent of the voltage sensing circuit. The first winding has a voltage proportional to the   alternator   main voltage (Shunt characte...
