M40FA610A ‘MGC I’ – Marelli AVR

Description

The voltage regulator type “MGC I”, is suitable for Synchronous Generators of MARELLI MOTORI make, M8B and 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 operation.

The M40FA610A is a analog automatic voltage regulator made by Marelli in Italy. The AVR’s main purpose is the sense and regulate the generator voltage and keep it at a constant reading by +/-1%
