Triac - works Kt16P single phase thyristor regulator / power adjustment trigger trigger board J3 positive bias due to the hole when the P2 area turned into N2 zone in the control electrode G on adding a forward voltage, N2 area The electrons enter P2 area SCR T435-600T, forming a trigger current IGT. Inside the SCR on the basis of positive feedback, with the role of IGT, the thyristor SCR is turned on in advance BT137S-600E, resulting in voltage characteristics, OA left SCR T435-800T, IGT more large, properties left sooner triac - Product identification 1, single, triac discrimination: first as two measuring pole, if positive and negative test pointer not moving (R × 1 block), may be A , K or G, A pole (on the way thyristor) may be T2, T1 or T2, G pole (for triac). SCR SCR _ BT137S-600E_ are provided by Wal-electronic Dongguan City is fertile Electronic Technology Co., Dongguan City is Wal-Electronic Technology Co., Ltd.
