Leroy Somer R450M AVR Voltage Regulator DESCRIPTION:

The R450M Leroy Somer Automatic Voltage Regulator was engineered and is manufactured exclusively by Leroy Somer, a French division of Emerson. Leroy Somer is the world’s largest AC Alternator manufacturer. The Leroy Somer R450M, a quality, original product made in France, has a one year international warranty and technical support. This brand new product is in stock and offers same day shipping worldwide.

The Leroy Somer AVR R450M offers single phase voltage sensing, and is designed for use with SHUNT/AREP and PMG excitation alternators. A switch on the unit is used to set it for either SHUNT/AREP or PMG use as desired. The AREP excitation is powered by two auxiliary windings that are not incorporated into the voltage sensing circuit. The first, SHUNT, winding’s voltage is about the same as the alternator main voltage. The second winding has voltage that is about the same as the stator current, and provides a booster effect. The power supply voltage is rectified and filtered. PMG excitation supplies the R450M with voltage separate from the main alternator winding, and provides a short-circuit current capacity of 3 IN for 10s. The R450M adjusts the excitation current to monitor the alternator output current.
