The rectifier assembly converts the alternating current (AC) produced by the alternator's stator windings into direct current (DC) that can be used to charge the battery and power the vehicle's electrical systems.
Typical output current ranges from 40 to 160 amperes at 6000 rpm, and the regulated output voltage is 14 ±0.5 V DC for 12V systems. These are reference ranges; confirm exact values for your specific model.
Common materials include silicon diodes, an aluminum heat sink, copper terminals, and epoxy encapsulation for protection. These materials provide electrical performance and thermal management.
Check the manufacturer's datasheet for the specific model, ensuring that parameters such as output current, voltage, temperature range, and mechanical dimensions match your alternator's requirements. Always verify with the legal manufacturer or supplier.
