The R449 automatic voltage regulator (AVR) for the LSA series of industrial alternators provides excitation current up to 7 A with excellent reliability for SHUNT, permanent magnet (PMG), or AREP excitation types.
The R449 features a voltage droop for Genset parallel operation and short circuit current limitation. The R449 is also equipped with a Load Acceptance Module (LAM).
