General information:

The voltage regulator 9402.3702-01 8A 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 VAZ-2108, -2109, -2110, -2111, -2112, -2113, -2114, -2115, -2121 and others with alternators 94.3701, 9402.3701, 977.3701, 3202.3771, G2112E; automobiles “Daewoo Lanos” 1.4i, “Daewoo Sens”, “Slavuta”, “Tavrija” after 2004 year of manufacture and others with alternators 97T.3701, 97S.3701; automobiles GAZ, UAZ with alternators 9422.3701, 3212.3771, 3282.3771 and others.

The voltage regulators 9402.3702-01 8А is applied in alternators with field winding 8A.

The automobile voltage regulator 9402.3702-01 8A is the regulator of a new generation. Due to usage of the modern powerful MOSFET 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. An operating mode of the regulator is S1 in accordance with GOST 3940.

The regulators are mounted directly on the alternator where the setting of regulators 9402.3702, 9402.3702-01, 9402.3702-02 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.
