General introduction:

The voltage regulator JA120M1 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 MAZ, KAMAZ and others with the alternator G273, 21.3771 and their modifications.

The given item is developed specially for exploitation in various latitudes with a large range of environment temperature, including also in tropical conditions.The regulator is produced in a single climatic design 2.1 in accordance with GOT 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°C

rviceability and correspondence of item parameters are saved even at plunging of the regulator to water under. The regulator JA120M1 is designed on a single-wire power circuit; the item housing is connected to the case of 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 JA120M or JA120M1 with the help of standard screws is stipulated.
