Voltage regulators 9402.3702-01, 9402.3702-02

General information

The voltage regulators 9402.3702-01 and 9402.3702-02 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.

Application: 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”, “Tavria” since 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 ensure the optimal charging mode of modern (“calcium” and others) batteries that require an increased charging voltage.

The regulators are produced in a single climatic design O2.1 in accordance with GOST 15150 for internal market and for export. On extent of protection against penetration of foreign bodies and water, the items meet design IP57 in accordance with EN 60529. An operating mode of the regulators is S1 in accordance with DSTU GOST 3940.

The regulators are mounted directly on the alternator, where is stipulated the setting of regulators 9402.3702, 9402.3702-01, 9402.3702-02 with the help of standard screws.

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 four years from the date of the item production. The date of production is marked on the case of the item housing.
