Product Description:
Automatic Voltage Regulator (AVR) AVR R250
R250 A.V.R. 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.
