LEROY SOMER R250 AVR FOR SHUNT AlterNATORS

Description

·         Leroy Somer R250 is an analog A.V.R. with numerical regulation function (micro-controler) and power controled by transistors.

·         It is designed for small alternators with a SHUNT excitation.

·         R250 Leroy Somer AVR controls the excitation current in order to maintain the output voltage of the alternator.

·         R250 AVR 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.
