GENERAL
The Leroy Somer R449 is used in applications where Ā PMG or AREP excitation systems are present. Ā Mostly installed in 3 phase applications but 1 phase operation is possible. When pared with a an R726 this will enable parallel synchronizing with the mains. When pared with the R731 this will allow 3-phase sensing across all the lines. The regulator has been on the Leroy Somer production line for several decades and still one of the most used automatic voltage regulators in today’s larger generator ends.
