BXE series: is a domestic car series is mainly Petrai and microcars, Petrai series of products are mainly sintered type of its heat sink is mainly aluminum die-casting its volume is larger, the microcar series of products to the press-fit type is the main, and its volume is not too big, most of the rectifier bridge with resistors and capacitors; basically by the eight main diodes plus three excitation tube; this series of products has a high-efficiency performance conversion, adaptable, durable and reliable, easy to install features; domestic trucks, microcars: represented by the Chang'an Star very good double-layer design makes this rectifier bridge performance is good, especially the excitation of market feedback did not fail. This series of products is characterized by high performance conversion, durability, reliability and easy installation; Domestic trucks and microcars: represented by Chang'an Star, very good double-layer design, which makes this rectifier bridge with good performance, especially the excitation diode with no failure in the market feedback. Van to Petra and Dehong (reference to the Faleo) design as a representative contains a variety of specifications, market feedback is good.
