Leroy Somer Original automatic voltage regulator/ AVR R449
Description
R 449 A.V.R. FOR AREP or PMG ALTERNATORS
R 449 is an analog A.V.R. It is designed for alternators with a AREP or PMG excitation . R 449 controls the excitation current in order to maintain the output voltage of the alternator. R 449 is performant in terms of voltage regulation, simple to set , to use and is reliable. It can run without LAM (U/f), or with LAM, selection is done by strap ST5. It is in compliance with I.E.C. 60034-1 standard and U.L. 508 / C.S.A. approved.
