Triac - thyristor plastic measuring method followed to determine T1 and G2 in contact with a red bar table T2, the two poles of the black rod contacting any remaining one (for the time being assumed as T1), then overflow multimeter should display the red stick-slip to the other electrode (for the time being assumed to G), so that the red bar shorting the two electrodes, if the display value is slightly lower than Ugt1 The company specializes in the supply of micro small volume of high pressure SCR BT134W-600E, uses SCR SOT223 package BT136S-600E, pressure up to 600V or more. Long-term supply, free samples, welcomed the talks. High-pressure one-way SCR in performance, not only with one-way SCR SCR conductive BT134W-600E, but also has more than silicon rectifier elements (commonly known as "dead silicon") is more valuable controllability. It only turned on and off states. SCR can milliamp current control high-power electrical equipment, if it exceeds this frequency, due to a significant increase in the device switching losses, allowing reduced the average current through the phase at this time, the nominal current should downgrade. SCR, is fertile Electronics (certified), SCR provided by the Dongguan City, is Wo Electronic Technology Co., Ltd. Dongguan City is Wo Electronic Technology Co., Ltd (www.dgmydz.com) (www.dgmydz.com) Dongguan, Guangdong, FET leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum Limits to meet customer needs. Wal-e-leadership in the positive with the staff warmly welcome all inquiries negotiations to create a positive fertile electronic better future.
