M16FA655A

The voltage regulator type"MARK V", is suitable for Synchronous Generators of MARELLI MOTORI make, MJB series, size range 160-225 frames. 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 generators.

MARELLI AVR M16FA655A  is our new design, It is very good performance and low price as well as original.
