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 e into the P2 region formed trigger current IGT. SCR BT137S-600E inside the SCR on the basis of positive feedback, coupled with the role IGT thyristor BT136S-600E, so that the thyristor is turned on in advance, resulting in the left section of the thyristor voltage characteristic OA , IGT bigger properties left sooner triac - Golden Rule Isolated Triac rule 2. To disconnect switch (switch) thyristor (or triac). Rule 3. When designing triac trigger circuit, whenever possible SCR T435-600T, we must avoid the three quadrants (WT2 -, +). Rule 4. To reduce clutter absorption, minimizing the length of the gate wiring. Return line connected directly to the MT1 (or cathode) SCR BT136S-600E, are fertile Electronics (certified), SCR provided by the Dongguan City is Wal-Electronic Technology Co., Ltd.
