Alternator Easy Spare Parts automatic voltage regulator 1000kva AVR
R450 For Diesel Generator Sets
Product Description
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 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 switches for U/f, LAM, excitation type, and voltage
sensing is available. It complies with I.E.C. 60034-1 standard and
U.L. 508 / C.S.A. approved
