Automobile alternators 42.3771 Series Print

                                                                                                        

Nominal voltage -14V, maximum currents - 80À and 100À.

There are about 10 modifications which differ in the dimensions of pulleys, 

presence or absence of a builtin voltage regulator, a setting option “Winter-Summer”, etc.

The alternator is applied to buses PAZ, trucks ZIL, GAZ and other as an energy resource in the electric system.             


Nominal voltage is 14V, maximum currents are 80À and 100À. There are about 10 modifications which differ in the dimensions of pulleys, presence or absence of a built-in voltage regulator, a setting option “Winter-Summer”, etc. The alternator is applied to buses PAZ, trucks ZIL, GAZ and other as an energy resource in the electric system. The following types of alternators series GG273B1-3 are produced by «Radiovolna»: 42.3771, 4201.3771, 4202.3771, 4202-1.3771, 4203.3771, 4203.3771-1, 4204.3771, 4205.3771. 4206.3771.

Alternator 4201.3771 (14V, 100À)

The alternator is applied to buses PAZ-4234,32053 produced by «Pavlovsky Bus Plant» and their modifications with engines D245 instead of alternator 28.3771 produced by ATE-1 PRAMO. Advantage – Maximum current is 25% higher as compared to analogs. Note: The installation diagram is different from that of alternator 28.3771.

Alternator 4202.3771, 4202-1.3771 (14V, 80À)

The alternator is applied to automobiles «Valday» GAZ -33104 with engines D245.7Å2 instead of alternators 1631.3701, 1637.3701 produced by ZiT, Samara. The alternator 4202.3771 is equipped with a voltage regulator with automated thermal compensation, the alternator 4202-1.3771 is equipped with a voltage regulator with two setting options “Winter-Summer” (Çèìà-Ëåòî). Advantage – Maximum current is 20% higher, the current output at minimal rotational speed is 50% higher. Note: The installation diagram is different from that of alternators 1631.3701, 1637.3701.

Alternators 42.3771, 4203.3771, 4203.3771-1 (14V, 100A)
