Leroy Somer AVR R220, for shunt alternators.
For LSA40 & LSA42.3 series alternators.
R220 is an analog AVR with power controled by transistors. It is designed for small alternators with a SHUNT excitation.
R220 controls the excitation current in order to maintain the output voltage of the alternator. R220 is performant in terms of voltage regulation, simple to set , to use and is reliable.
It is in compliance with I.E.C. 60034-1 standard and U.L. 508 / C.S.A. approved.
