Leroy Somer Alternator Genuine AVR R450

Leroy somer alternator AVR R450 

R 450 is an analog A.V.R.. It is designed for alternators with a SHUNT, AREP or PMG excitation.
R 450 controls the excitation current in order to maintain the output voltage of the alternator.
R 450 is performant in terms of voltage regulation, simple to set , to use and is reliable. Rotating switch for U/F, LAM, excitation type and voltage sensing are available. It is in compliance with I.E.C. 60034-1 standard and U.L. 508 / C.S.A. approved
