1.Marelli AVRM40FA640A

The voltage regulator type “MARK I”,is suitable for Synchronous Generators of MARELLI  MOTORImake, MJB series, size range 160-500 frames. This regulator isproper to operate on machines rated from 10 up to 2000 kVA. Theregulator is fully insulated in order to maintain high reliabilityalso with severe ambient conditions (high level of humidity, dust,salt atmosphere), and in case of high vibrations level. Theregulator is proper both for single
and 3-phase operation.
