General information:

The voltage regulators 9111.3702, 9111.3702I2, 9111.3702I4 and 9111.3702I6 are 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, and others with alternators 94.3701, 9402.3701, 977.3701, 3202.3771, G2112E, ELD-A-2110, ELD-A-21214, ELD-A-2123; 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 9111.3702, 9111.3702I2 and 9111.3702I6 are used with modern (calcic) accumulator batteries, which require the increased voltage of the battery charge.

These regulators are regulators of the new generation. Due to the usage of an additional wire the voltage is analyzed directly on the alternator output terminal, which ensures the exactness of the alternator output voltage independently from the alternator speed, battery quality , as well as from the rate of its electrical load. This prolongs battery life cycle, provides optimal operating modes of all using equipment increasing thus reliability of all automobile electrical equipment.

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 regulators are 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 regulators is S1 in accordance with GOST 3940.

The regulators are mounted directly on the alternator where the setting of regulators 9402.3702, 9333.3702, 9111.3702 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 items.
