General information:

The multifunctional voltage regulator 3252.3702 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.

Applicability: automobiles MAZ (Euro-3) with the engine JAMZ-656, JAMZ-658 and others with the alternator 3252.3771.

Additional diodes in the rectifier unit are absent, the control of alternator’s start-up and control of its rotation frequency is made directly on one of the output power control windings.

The voltage regulator 3252.3702 has a function of indication of the on-board network reduced/increased voltage and the alternator's low phase voltage. The indication is realized by glowing of the indicator lamp controlling the battery loading on the instrument cluster. The item ensures the fulfilment of a function of fading in current load. The voltage regulator 3252.3702 realizes also a function of protection against short-circuit in the output and indicator circuit.

The regulator is produced in a single climatic design О2.1 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 IP67 in accordance with GOST 14254. An operating mode of the regulator is S1 in accordance with GOST 3940.

The item is mounted directly on the alternator, where the setting of regulators 3252.3702 or 7941.3702V3 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 case of the item.
