General information:

The voltage regulator 9722.3702 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 frequence of the alternator rotor, electrical load and environment temperature.

The distinctive feature of the given item is presence of the indication function of voltage excess of onboard vehicle network more than 15 V. At the exceeded voltage of the onboard vehicle network the regulator ensures indication of this mode by blinking with the frequence 2 Hz of a standard indicator lamp controling the charging of battery on the instrument cluster.

The voltage regulator 9722.3702 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.

Applicability: automobiles with the alternator 97.3701 or other alternators of the row 97хх.3701 (except 97T.3701) with the minor retrofiting of the alternator`s cap.

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 item housing.
