Voltage regulators 9222.3702, 9222.3702I2, 9222.3702I3, 9222.3702I4, 9222.3702I6

General information:

The voltage regulators 9222.3702, 9222.3702I2, 9222.3702I3, 9222.3702I4, 9222.3702I6 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.

Application: automobiles KAMAZ, MAZ with alternators 4502.3771, 3232.3771 and their modifications.

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

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.

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.

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 JA222B, 3232.3702, 9222.3702 and 9222.3702I3 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.
