SCR Thyristors SCR full name (also known as SCR, abbreviation SCR): is a power semiconductor devices. It has a large capacity, high efficiency, good controllability, long life and small size of many strengths SCR, is accused of manipulation and weak bridges between strong electricity. From the energy point of departure, hailed as the new electric power electronics skills skills. China's power usage is low, according to the national production of energy yield calculation, China is 4.98 times that of France, Japan, 4.43 times, and thus to the thyristor (SCR) as the center of the increasing use of electrical control equipment is useful for saving China An important measure of electrical energy. SCR triac test. R * 1Ω resistance with a multimeter block, with a red, black and two pen were measured between any two pins positive and negative resistance, the result of which two readings of infinity. If a group of tens of ohms, the group of red and black two-pin connection table for the first anode A1 and the gate G, the other foot is the empty second anode A2. Determine A1, G pole, and then carefully measured A1, G pole between positive and negative resistance readings that measure relatively small black table pen connects to pin the first anode A1, take the red pen pin control electrode G. The black pen then identified a second anode A2, the red pen then the first anode A1 SCR T405-600T, this time should not deflect the meter pointer, resistance is infinite. Then the short wires will A2, G very short instant, giving G pole with a positive trigger voltage, about A2, A1 between the resistance of about 10 ohms. Then disconnect the A2, G between short wiring multimeter reading should remain around 10 ohms. Interchangeable red and black pen wiring, the red pen then the second anode A2, black pen then the first anode A1. Similarly multimeter pointer should not occur T405-800T SCR deflection, resistance is infinite. With short connection to A2, G again very short moment between, plus resistance to G very negative trigger voltage, A1, A2 is between about 10 ohms. Then disconnect the A2, G extremely short wiring between the multimeter reading should remain unchanged, maintained at about 10 ohms. Comply with the above rules, instructions and test triac undamaged three pins to determine the polarity is correct. Greater power to detect when the SCR requires a single 1.5V batteries in series multimeter black pen in order to improve the trigger voltage. Discrimination thyristor (SCR) SCR pin pin discrimination by the following methods: first with a multimeter to measure the resistance R * 1K block between tripod SCR T435-800T, the resistance of small feet were controlled and cathode, anode remaining foot. Then multimeter R * 10K block, with fingers anode and the other foot, and do not let the feet touching, black pen then the anode, the red pen then the rest of the foot, such as the swing to the right hands, indicating that the red pen The connection to the cathode, a control electrode was not swinging.
