LEROY SOMER R438 is used with AREP or PMG excitation on LSA42.3, LSA43.2, LSA44.3, LSA44.2 Leroy Somer models. For shunt application we recommend the R250 or R220 which will provide you the necessary regulation control. The R438 is among one of the oldest regulators but one of the best Leroy Somer has to offer. With its regulation of -/+1.0 the R438 can hold its voltage even in the worst industry load demand conditions.
