The voltage regulator type “MARK V”, is suitable for synchronous generators of MARELL make MJB series, size range 160-250 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.

The M16FA655A is a automatic voltage regulator made by Marelli in Italy.
This regulator senses 2 phases and adjusts excitation when needed.  An external potentiometer can be installed to adjust voltage (sold separately)

Can be used on Marelli MJRM, MJRT, MJT, MJBM, MJVM, MJB MJR, MJV, MJB, MJR,  MJHRT Generator frames.
