WebbSCRs are often used where a large amount of power is to be switched, but the contact current and voltage must be kept low for simple and reliable operation. The SCR provide a solution to this common control problem. The sensitive actuating contacts need supply only the gate firing power, which can be as low as 50 microwatts (1 V, 50 µA).

SCRs are mainly used in devices where the control of high power, possibly coupled with high voltage, is demanded. Their operation makes them suitable for use in medium- to high-voltage AC power control applications, such as lamp dimming, power regulators and motor control. SCRs and similar devices are used for rectification of high-power AC in high-voltage dc power transmission. They are also used in the control of welding machines, mainly GTAW (gas tungste… WebbSCRs can control the main parameters—voltage, current or power—from zero to 100 percent with almost infinite resolution, allowing for accurate, stepless control of the process. • Reliability with minimal maintenance.
