General information:
The voltage regulator JA112B1 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: tractors DT-75C, T-25, T-30, TDT-55 and others
with alternator 46.3701, and its modifications as well as
tractors MTZ, combines "Yenisei", "Kolos",
"Niva", "Sibiryak", SK-6 and others with
alternator 96.3701 , and its modifications.
A long-term operation without the battery is permited. Specially for this mode the item has the improved parametres of self-excitation. 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 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 regulators JA112B or JA112B1 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.
