The CQ220-12B is classified into the group of thyristors - TRIACs, a type of electrical switch that functions as an electrically controlled rectifier for alternating current (AC). The CQ220-12B is a versatile device that offers a wide range of applications in the industrial sector. This article will discuss the general working principles of a TRIAC as well as the application field of the CQ220-12B. TRIACs are semiconductor devices that are composed of three mutually interconnected thyristors in the same package. The device acts as a 3-wire switch that functions by electronically controlling the positive and negative sides of the alternating current. This is accomplished by monitoring the transitions between negative and positive voltage. Both positive and negative pulses of one or two quadrants of the sine wave can be triggered by a single input pulse.The CQ220-12B is designed for different types of industrial applications. It is especially suitable for use as a control element in times when there is a need for a short circuit current with high inrush currents up to 50 Hz. The device also features a unique set of features that enable higher production efficiency and a reduction in time-to-market. The CQ220-12B serves primarily as a static switch in applications such as rectifiers, contactors, UPS, and fans. In addition, it is used for the direct control of AC motors, lightweight power applications, and power supply systems.The CQ220-12B is based on SCR technology and comprises three electronically interconnected thyristors. Its design enables individual control of the negative and positive phases of the current, with each phase using a single control element. The device also features on-state current rating of up to 50A and peak surge current ratings of up to 70A. Its higher switching capacity helps ensure a high level of efficiency and improved performance in the application. Apart from its use in static switches and AC motors, the CQ220-12B is also well-suited to current measurements. The device is designed to improve accurate current measurements in both single-phase and three-phase systems. With its built-in temperature compensation feature, it can also reliable measure current in high-temperature applications such as welding.The CQ220-12B is a reliable and durable device that is easy to install and use. This device is UL and CSA certified for safety and rated for operation up to 125°C. It comes with a one-year guarantee and is currently available in the global market. In conclusion, the CQ220-12B is an excellent choice for industrial and production applications requiring the control of current. Its unique features, combined with its high-performance and reliability make it a suitable solution for a wide variety of applications. This device’s effective switching capabilities ensure higher production efficiency and reduced time-to-market, making it a cost-effective choice.
