General information:

The voltage regulator 9762.3702 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, KAMAZ and others with the alternator 976.3701.

The voltage regulator 9762.3702 is the regulator of a new generation. Due to usage of the modern powerful field-effect transistor as an output switch, the highest parameters of the current velocity characteristic are reached, the power losses are sharply lowered and the item reliability as a whole enlarged.

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. All electrocontact connecting elements of the regulator are made of brass rolling with a galvanic cover that guarantees reliability of the electrical connections during all service period. 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 9762.3702 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.
