The R450 includes advanced protections such as over-excitation limitation and voltage sensing loss and also features voltage droop for Genset parallel operation. The R450 is also equipped with a Load Acceptance Module (LAM) to handle load impact events.
R450 AVR is an analog A.V.R. It is designed for alternators with a SHUNT, AREP or PMG excitation.
R450 AVR for Genset controls the excitation current in order to maintain the output voltage of the alternator. R450 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
Operation mode : Standalone
