General information:
The voltage regulator JA212A11 (Я212А11) 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.
Application: automobiles with carbureted engines VAZ-2108, -09, -10, VAZ-21213, “Oka” with an alternator 37.3701 or its modifications.
As an output switch is used a modern powerful field-effect transistor owing to that the losses of power given off in the form of heat have been sharply lowered, the load and current high-speed characteristics of the item have been improved and the regulator reliability has been enlarged.
The regulator is produced in a single climatic design O2.1 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 IP57 in accordance with EN 60529. An operating mode of the regulator is S1 in accordance with DSTU GOST 3940.
The regulator is mounted directly on the alternator, where is stipulated the setting of regulators JA212A11 with the help of standard screws.
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 four years from the date of the item production. The date of production is marked on the case of the item housing.
