General information:
The voltage regulator 4572.3702 is purposed for voltage maintenance of the onboard
vehicle network in predetermined limits in all system operation modes of electrical
equipment at change of the rotation frequency of the alternator rotor, electrical load and
environment temperature.
Applicability: automobiles MAZ-2108 with the engine JAMZ-7511, KAMAZ with the engine
KAMAZ-740 and others with the alternator 4572.3771 and its modifications.
The regulator is produced in a single climatic design О2.1 in accordance with GOST 15150
for internal market and for export. On protection degree against penetration of foreign
bodies and water, the item meets design IP68 in accordance with GOST 14254. An operating
mode of the regulator is S1 in accordance with GOST 3940.
The regulator is mounted directly on the alternator where the setting of regulators
9402.3702 with the help of standard screws is stipulated.
The warranty period of exploitation is 3 years from the date of commissioning or from the
date of sale in retail commercial network. The warranty obligations of the manufacturer
are valid during 4 years from the date of the item production. The date of production is
marked on the case of the item.
