Voltage regulator 4572.3702

General information:

The voltage regulator 4572.3702 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.

Application: automobiles MAZ with an alternator 3112.3771-01, KAMAZ (Euro-0, Euro-1) with alternators 3122.3771-01, 3142.3771-01.

The regulator is produced in a single climatic design O2.1 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 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 4572.3702 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.
