What is the Acim Nidec R450?

The R450 automatic voltage regulator (AVR) for the LSA series of industrial alternators provides excitation current up to 6 A with excellent reliability for SHUNT, permanent magnet (PMG) or AREP (auxiliary winding) excitation types.

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.
