M40FA640A

The voltage regulator type “MARK I”, is suitable for synchronous genetors of Marelli Motori make MJB series, size range 160-500 frames. This regulator is proper to operate on machines rated from 10 up to 2000kVA. 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.
