Marelli Automatic Voltage Regulator (AVR) Mark
I for MJB 250 / 315 / 355 / 400 / 450
The voltage regulator type "MARK I", is suitable for Synchronous
Generators of MARELLIGenrators 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
