Triac - thyristor voltage characteristic way into the electron and hole into the P2 region N1 respective regions not all complex off thyristor BT134W-600E, so that there is in the area of ??electronic accumulation thyristor N1 T405 -800T, there is a hole in the P2 area accumulated SCR BT136S-600E, resulting in a potential increase of P2 area, the potential drop zone N1 triac - works Kt16P single-phase thyristor voltage regulator / power adjustment 1. SCR trigger board is P1N1P2N2 four three-terminal structural elements, there are three PN junction, the analysis principle, it can be treated as having a PNP transistor and an NPN transistor formed. When the anode A with a positive voltage, BG1 and BG2 tubes are in the enlarged state. SCR T405-800T, being fertile Electronics (certified), SCR provided by the Dongguan City, is Wo Electronic Technology Co., Ltd. Dongguan City is Wo Electronic Technology Co., Ltd (www.dgmydz.com) (www.dgmydz.com) Dongguan, Guangdong, FET leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum Limits to meet customer needs. Wal-e-leadership in the positive with the staff warmly welcome all inquiries negotiations to create a positive fertile electronic better future.
