M16FA655A Automatic Voltage Regulator is developed by Marelli suitable for Three-phase Synchronous Generators. Which is provided with internal circuits in order to reduce the excitation, when running at low speed, in order to avoid damages to the excitation system of the generator.

 

1. Marelli Automatic voltage regulator  

2. The voltage regulator type "MARK V", is suitable for Synchronous Generators of

MARELLI MOTOR make
3. Fully insulated in order to maintain high reliability also with severe ambient

Conditions (high level of humidity, dust, salt atmosphere), and in case of

high vibrations level
4.Proper both for single and 3-phase generators
