General information:
The multifunctional voltage regulator 9333.3702-04 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.
The differential characteristic of voltage regulator 9333.3702-04 is a built in
interference-suppression capacitor.
Applicability: automobiles VAZ-2110, VAZ-2111, VAZ-2112 with alternator 9402.3701-03;
VAZ-2123 “Chevrolet Niva” with alternator 9402-3701-04 and others.
Multifunctional voltage regulator 9333.3702-04 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 regulator 9333.3702-04 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 fulfilment 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 foreign automobiles
of high class are built.
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.
An operating mode of the regulator is S1 in accordance with GOST 3940.
The regulator is mounted directly on the alternator where the setting of regulator
9333.3702-04 with the help of standard screws is stipulated. The application of
regulator 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 4 years from the date of the item production. The date
of production is marked on the case of the item.
