Marelli Voltage Regulator - M25FA645A - 10004750<\/p>\n

The voltage regulator (code n \u00b0 M25FA645A), is suitable for MARELLI MOTORI brand Synchronous Generators, M8B series, size range 200 - 250 frames. This regulator is suitable to operate on machines from 50 to 300 kVA. The regulator is completely isolated to maintain high reliability also in severe environmental conditions (high humidity, dust, saline atmosphere) and in case of high vibration level. The regulator is suitable for both single-phase and three-phase operation.<\/p>\n
