Description
R450 Genuine Leroy Somer AVR for the LSA series of industrial alternators delivers excitation current up to 6 A with high reliability for SHUNT, permanent magnet (PMG), or AREP (auxiliary winding) excitation types.
The R450 Genuine Leroy Somer AVR 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.
Designed to equip alternators with SHUNT, permanent magnet (PMG), or AREP (auxiliary winding) excitation types from LSA40 to LSA50.2 and TAL46 to TAL49.
These are brand new, GENUINE LEROY SOMER AVRs straight from the factory.
