---- Free buffer three quadrant triac series features: advanced glass passivation and polysilicon double protection bca55 thyristors, low on-state voltage drop, high junction temperature, high noise immunity, free buffer circuits, high reliability and stability through ROSH certification application: Mainly for dimming, thermostats, electronic oven, washing machine, air conditioning, soybean milk, curlers, welcome home, drinking fountains, lawn machines, shredders, mahjong machines, power tools, etc. appliance control circuit, and AC phase control, drive and solid-state relays, and other circuits. Dongguan factory triac spot BTA80-800B wholesale authentic agent of the triode thyristor, thyristor rectifier element is referred to, is a kind of power semiconductor devices of three four-layer structure of the PN junction, also known as thyristors. With a small, relatively simple structure, function, and other characteristics, is one of the more commonly used semiconductor devices. The device is widely used in various electronic devices and electronic products, mostly used as a controlled rectifier, inverter, frequency, voltage, non-contact switches. Household Appliances dimming lights, speed fans, air conditioners, televisions, refrigerators, washing machines, cameras, hi-fi, sound and light circuit, timing controller, toys device, radio-controlled, camera and so widely used in industrial control SCR devices. 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 European bta60-800b thyristor, triac it certainly is. Then dial knob to R × 1 or R × 10 block retest, during which time the resistance must be slightly larger, slightly larger than a red pen is connected to G pole, black pen pole connected to T1, T2 remaining is extremely . 2, the function is not the same: the knob dial to R × 1 block, about 1 ~ 6A way thyristor, thyristor pole red pen then K, together turned black pen G, A pole, while adhering to the black pen without departing from the A Under extreme conditions pole disconnect G, 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 T2 pole or pole-pole disconnect G bca60-1600 thyristor pointer immediately return ∞ position is clarified 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.
