Triac - trigger circuit SCR3 with the surrounding elements constituting ordinary phase-shift trigger circuit SCR T435-800T, its principle is omitted here. SCR1, SCR2 selection of packaged SCR module (110A / 1000V), SCR3 selection BTl36, namely 600V triac. This circuit is used as an inductive load, should increase the R4, C3 RC snubber circuit and overvoltage protection for SCR varistor RV BT137S-600E, prevent the load off and on instantly generate high voltage induced damage controllable Silicon Triac - works Kt16P single phase thyristor regulator / power adjustment trigger board at this time, if the control electrode G Enter a positive trigger SCR T435-600T, BG2 there ib2 base flow flowing by BG2 zoom, its collector current ic2 = β2ib2. Because direct collector electrode connected BG2 and BG1 base, so ib1 = ic. SCR T435-800T | SCR | are fertile Electronics Dongguan City is provided by Wal-Electronic Technology Co., Ltd.
