General information:
The voltage regulator 9763.3702 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: vehicles with the alternator 972А.3701 and
its modifications.
The voltage regulator 9763.3702 is the regulator of a new
generation. Due to usage of the modern powerful field-effect
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.
The regulator 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 IP68 in accordance
with GOST 14254. All electrocontact connecting elements of
the regulator are made of brass rolling with a galvanic cover
that guarantees reliability of the electrical connections
during all service period. 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 9763.3702 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.
