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
