The restrictive rectifier unit BVO11-150-12.21 (БВО11-150-12.21) is purposed for rectification of the three-phase alternating current and limitation of the impulse of overvoltage in the system of auto electrical equipment composed of alternator set.
Application: automobiles VAZ-2123, “Chevrolet Niva” with an alternator 9772.3701 and others.
The restrictive rectifier unit BVO11-150-12.21 is produced with a pressed-in M6 output bolt.
BVO is produced in a single climatic design O2.1 in accordance with GOST 15150 for internal market and for export. The operating mode of the alternator – S1 in accordance with DSTU GOST 3940.
The restrictive rectifier unit is mounted directly on the alternator, where is stipulated the setting of rectifier units BVO11-150-12.21, with the help of standard fixture elements. For the reduction of transient junction resistance of alternator power circuits the stator winding is connected to the unit by soldering.
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.
