General information:
The voltage regulator JA112B1-2 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: automomobiles GAZ 33104 and
others with
alternators 4202-1.3771, 221.3771 and
221.3771-01.
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. Against moisture
penetration the regulator is protected by
special high-heat-conducting compound with an
operating temperature up to 200 °С.
Serviceability and correspondence of item
parameters are saved even at plunging of the
regulator into water under condition of
protection of demountable joints. The regulator
JA112B1-2 is designed on a single-wire power
circuit, the case of the item is connected to
the case of the vehicle. An operating mode of
the regulator is S1 in accordance with GOST
3940.
The regulator is mounted in the brush unit of
the alternator
where the setting of regulator JA112B1-2
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
item housing.
