Supply genuine original SCR SCR MURF1620CTOK welcome to order 1: Low-power plastic triac typically used as sound and light control lighting system. Rated current: IA less than 2A. 2: large; the power of plastic and iron seal is commonly used as a power thyristor controlled regulator circuit type. As can the regulator output DC power and so on. 3: High Frequency SCR is usually used as the industry; high-frequency melting furnace. 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, during which there must be a resistance slightly bt131m SCR patch is slightly larger than a red pen then for G pole, black pen connects to T1 pole, the rest is extremely 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 Disconnect the G under extreme conditions, the pointer should indicate dozens of Europe to one hundred Euro patch SCR to-263, this time has been triggered thyristor, 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 an outstanding mac97a6s patch SCR SCR, 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 approach can further measure the patch SCR, 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. Mcr100-6m SCR patch, patch SCR, are fertile Electronics Dongguan City is provided by Wal-Electronic Technology Co., Ltd.
