- Type： R450
- Product Summary：
Compatible Leroy somer R450 AVR is powered by two auxiliary windings which are independent of the voltage equal circuit. The power supply voltage is rectified and filtered before being used by the AVR monitoring transistor. With PMG excitation, a permanent magnet generator (PMG) added to the alternator supplies the AVR with voltage. ...
Product description:
The R450 AVR is supplied in a casing designed to be mounted on a panel with dampers. Both the SHUNT/AREP & PMG excitation systems are controlled by the AVR. With AREP excitation, the electronic AVR is powered by two auxiliary windings which are independent of the voltage sensing circuit. The connection is realised by “Faston”connectors and the voltage sensing is single - phase.Operating temperature: - 30℃ to + 65℃.Good stability and high quality.
Main features:
1. Compatible Leroy Somer Automatic Voltage Regulator R450
