This is replacement AVR made in China on high quality, this AVR can replace original R130 AVR complete.
1 - GENERAL
1.1 - Presentation
This technical manuel concerns the three products of the
R130 range identified by R130A, R130B, R130C.
This products 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
1.2 - Description
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 (see alternator
instructions).
The purpose of the regulator is to shunt the excess
exciting current in order to maintain the voltage at its
rated value.
