The LSA411 Rectifier Series (often identified as the SSAYEC411 or ALT411KD001) is a rotating diode bridge assembly designed for Leroy Somer alternators. It is specifically tailored for the LSA 41.1 series of alternators, typically found in smaller generator sets ranging from 10 kVA to 30 kVA.
Like its larger counterparts, this bridge is mounted on the exciter rotor and serves the critical function of converting the AC output from the exciter armature into the DC current required to energize the main magnetic field of the rotor.
