Voltage regulators 5102.3702, 5102.3771.060

General information:

The voltage regulators 5102.3702 and 5102.3771.060 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-2108i, VAZ-2109i, VAZ-2110i, VAZ-2111, VAZ-2112, VAZ-2113, VAZ-2114, VAZ-2115 and others with alternator 5102.3771 and its modifications.

The voltage regulator ensures the optimal charging mode of modern (“calcium” and others) batteries that require an increased charging voltage.

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 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 item meets design IP57 in accordance with EN 60529. An operating mode of the regulator is S1 in accordance with DSTU GOST 3940.

The regulators are mounted directly on the alternator, where is stipulated the setting of regulators 881.3702, AER1614, 5102.3771.060 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.
