Triac BT134-600E supply genuine authentic professional supplier of power devices, inventory stock Working hours: Monday to Sunday: 9: 00-17: 30. Holiday orders not shipped Delivery time: daily 17:00 paid before the day of delivery, the city with the city to pay for emergencies morning there may be contact with the treasurer priority bt134w patch SCR, a rate not contact pm central licensing . 17:00 every day before the payment, purchase details are not more than 10, the day of delivery. 5:00 After payment, purchase details over five and next day delivery. SCR 1, single, triac distinction: the first one of the two measuring pole, if positive and negative test pointer not moving (R × 1 block), may be A, K or G, A pole (one-way SCR) may also be T2, T1 or T2, G pole (for triac). If there have been a measure indicative of tens to hundreds of Europe, it certainly is way thyristor. And a red pen for the connected K-pole, black pen then for G pole, namely A remaining pole. If the positive and negative test instructions are tens to hundreds of Europe, certainly for the triac. Then dial knob to R × 1 or R × 10 block retest bt137s patch SCR, during which there must be a resistance slightly SCR, the slightly larger one red pen then for G pole, black pen T1 connection is very, very remainder is T2. 2, the function is not the same: the knob dial to R × 1 block, about 1 ~ 6A way thyristor, red pen then K pole, black pen together turned G, A pole, while adhering to the black pen without departing from the A pole Under extreme conditions T410 G patch off thyristor, the pointer should indicate dozens of Europe to one hundred in Europe, this time the SCR has been triggered, and the trigger voltage is low (or trigger current is small). A pole momentary disconnect and then on again, the pointer should be returned ∞ position, then marked SCR outstanding. About 1 ~ 6A triac, red pen then T1 pole, black pen together pick G, T2 pole, black pen in ensuring the premise without departing from the T2 pole disconnect G pole, the pointer should be instructed to tens to hundred Europe (depending on the current size of the SCR, the manufacturers are not the same but different). Then swap the two pens, repeat the process measured once, pointer even slightly larger than the last time to a few dozen in Europe, it marked SCR outstanding, and the trigger voltage (or current) is small. If you insist on turning A pole or pole disconnect G T2 pole position pointer immediately return ∞, then clarify the SCR trigger current is too large or damaged. Figure 2 can be further measured way, on a one-way SCR, closing the switch K, lights should be lit, disconnect the lamp is still interest K off, or to clarify SCR damage. About triac, closing the switch K, lights should be lit, disconnect K, lights should be quenched. Then reverse battery, repeat the process, the outcome should be the same, it is good to clarify. Otherwise stated that the equipment has been damaged. Bt136s patch SCR, SCR, are fertile Electronics Dongguan City is provided by Wal-Electronic Technology Co., Ltd.
