General information:

The voltage regulator JA112V1 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-2104, VAZ-2105, VAZ-2107, "Tavria" (till 1991) with the alternator G222 and others.

The given item is developed specially for exploitation in various latitudes with a large range of environment temperature, including in tropical conditions also.

The regulator is produced in a single climatic design О2.1 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 IP68 in accordance with GOST 14254. Against moisture penetration the regulator is protected by special high-heat-conducting compound with an operating temperature up to 200 °С. The regulator JA112V1 is designed on a single-wire power circuit; the case of the item is connected to the vehicle housing. An operating mode of the regulator is S1 in accordance with GOST 3940.

The regulator is mounted in the brush unit of the alternator where the setting of regulators JA112V or JA112V1 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.
