The EMRI LX449 (V1.5.8.2) is an automatic voltage regulator belonging to a generator’s automatic voltage regulator system. Its task is to set the excitation delivered to the alternator field, keeping terminal voltage on target as electrical demand across the vessel shifts. This build carries firmware V1.7.3 and hardware revision V1.6.3, with the markings NR: 2086, PROD: 4220 and BATCHNR: 22200382 identifying the individual unit. Without correct regulation, generators can deliver unstable voltage to the switchboard and the consumers it feeds. The regulator is supplied in Used condition.
