The voltage regulators 9333.3702-04, 9333.3702-04 ver.11 (9333.3702-04 исп.11), 9333.3702-04 ver.12 (9333.3702-04 исп.12) 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-2110, VAZ-2111, VAZ-2112 with an alternator 9402.3701-03; VAZ-2123 “Chevrolet Niva” with an alternator 9402-3701-04 and others.
The voltage regulators 9333.3702-04, 9333.3702-04 ver.11, 9333.3702-04 ver.12 ensure complete switching-off of the alternator’s field winding from the onboard network, thus increasing the reliability and safety of the vehicle power-supply system.
The voltage regulators 9333.3702-04, 9333.3702-04 ver.11, 9333.3702-04 ver.12 has a function of indication of the on-board network reduced/increased voltage and the alternator's low phase voltage. The indication is realized by glowing of the indicator lamp controlling the battery loading on the instrument cluster. The item ensures the fulfillment of a function of fading in current load. The regulator realizes also a function of protection against short-circuit in the output and indicator circuit.
The voltage control and regulation are performed directly on the alternator’s output terminal - on this principle all power supply diagrams of modern automobiles of high class are built.
An interference suppression capacitor is a part of the regulator.
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 IP67 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 9333.3702-04, 9333.3702-04 ver.11, 9333.3702-04 ver.12 with the help of standard screws. The application of regulators of the given types instead of the voltage regulators 7931.3702I4, 844.3702, 845.3702, 9444.3702 is possible, but with dismantlement of the standard filter capacitor.
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.
