Genuine Leroy Somer 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.

Designed to fit LSA40 to LSA50.2 and TAL46 to TAL49 alternators with SHUNT, permanent magnet (PMG) or AREP (auxiliary winding) excitation types.

These are new and GENUINE LEROY SOMER AVRs direct from the factory.

Details

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.
