There are 3 types of Rectifier / Regulators (Voltage Regulator Stabilizer) depending on phase of wave.
It is normally connected with AC generator to regulate the electrical power charging to battery. In case of buring or overheat the battery even whole vehicle, this component is essential to check regularly if your regulator is working well.
Rgeulator details as following :
Continuous catching test: < 350 hrs
Using temperature : -35 ~ +115 degree C
Materials: advantages of automatic angle entering. Lager convert energy, correct speed increasing and voltage entering and broad temperature range and so on.
