General information:
The multifunctional voltage regulator 9454.3702 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 VAZ-1117, -18, -19, “Kalina”, VAZ-2170, -71, -72 "Priora", VAZ-2190
"Granta" and others with the alternator 9402.3701-06, 9402.3701-14. The voltage regulator
9454.3702 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 9454.3702 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 regulator is
made with the usage of a modern microcontroller and by certain parameters it has no equal among
large-series produced items.
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.
The multifnctional regulator 9454.3702 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 SHCHR-5,
849.3702 or 9454.3702 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.
