Description
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 voltage droop for genset parallel operation and short circuit current limitation. The R449 is also equipped with a Load Acceptance Module (LAM).
