General information:
The multifunctional voltage regulator 9464.3702 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 “ZAZ Lanos” 1.5i, “Daewoo Nexia”,
“Chevrolet Aveo”, “Chevrolet Lanos” and others with the
alternator 9751.3701
The voltage regulator 9464.3702 ensures 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 9464.3702 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. Alternator startup control and control of its shaft
rotation frequency is performed directly on one of the output
power windings. An interference suppression capacitor is a part
of the regulator.
The multifnctional regulator 9464.3702 is produced in a single
climatic design О2.1 in accordance with GOST 15150 for internal
market and for export. On protection degree against penetration
of foreign bodies and water, the item meets design IP67 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 regulators 9464.3702, 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.
