APPLICATION
The AVR M40FA640A is suitable for Synchronous Generators of MARELLI  MOTORI make, MJB series, size range 160-500 frames. This regulator is proper to operate on machines rated from 10 up to 2000 kVA. The regulator is 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. The regulator is proper both for single and 3-phase operation.
