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. Single SCR, triac discrimination: first one of the two test poles SCR BTA216, if the positive and negative test pointer not moving (R × 1 block) SCR BTA412Y, may be A, K or G, A pole (on the way thyristor) may be T2, T1 or T2, G pole (for triac). If one has a measurement instructions for 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, and the rest is the A 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, which must have a resistance slightly SCR BTA140, the slightly larger one red pen then for G pole, black pen connects to T1 pole, The remaining is T2 pole. SCR BTA312, SCR, are fertile Electronics Dongguan City is provided by Wal-Electronic Technology Co., Ltd. Dongguan City is Wal-Electronic Technology Co., Ltd.
