LEROY SOMER R130 AVR FOR LEROY SOMER ALTERNATORS

LEROY SOMER AEM230RE002

General Description / Specifications

The R130 AVR is a subtractive regulator connected to a compound circuit. This set up is adjusted to provide a voltage higher than the rated voltage.The purpose of the regulator is to shunt the excess exciting current in order to maintain the voltage at its rated value.

This product are designed to operate on the entire range of alternators, from 100 to 3000 kVA.For example, regarding our own range there is a mandatory
relationship between :

> types AA44, 46, 47 generator and R130A
> types AA49, 50, 52 generator and R130B
> types AA54 and over generator and R130C
