NEW AVR SR7 SR7-2G AVR SR 7/2 AVR SR7 AVR SR 7 for MECC ALTE SR7-2G
DI JAMIN ANDA PUAS 100%
The SR-7 type voltage regulator is an advanced design electronic 5 Amp regulator that ensures excellent performance of the alternators while they are running and during starting. The regulator is equipped with a complete protection system against operation conditions that could be dangerous for the machine. The SR-7 regulator is suitable for being used with all alternators and is standard supply for power outputs below 85 kVa, both three-phase and single phase
Weight = 275 g 2% and Product Dimensions 97.0 x 92.0 x 39.0 mm
