Inrush current limiters, or ICLs, are a type of circuit device that are used to limit the amount of current that flows through an electronic component or system during an initial power-on event. One type of ICL is the CL-21B.

The CL-21B is an inrush current limiter specifically designed for AC/DC power supply systems. Its most notable feature is its ability to protect components from unexpected surges in power, making it ideal for high availability applications. It is also capable of limiting both AC and DC inrush currents, allowing it to be used for a variety of different applications.

The working principle behind the CL-21B is simple. It operates by using a voltage-limiting element, such as a zener diode or a varistor, to limit the amount of current that can flow through it during an initial power-on event. This prevents large inrush currents from damaging the electronic component and the associated power supply system.

The CL-21B has a wide range of applications, including consumer electronics, industrial systems, telecom systems, and digital signages. It is also suitable for applications that require high safety and reliability standards, such as medical devices, military and aerospace systems, and high-availability infrastructure.

In addition to its wide range of applications, the CL-21B also boasts a number of features that make it an excellent choice for inrush current limiting. It is capable of limiting up to 260A of inrush current, and its response time of only 0.5 milliseconds is one of the fastest in its class. It also offers over-current protection and reverse polarity protection for added safety.

Overall, the CL-21B is an excellent choice for those looking for an inrush current limiter that is both reliable and cost-effective. It is capable of limiting high levels of inrush current with a fast response time, making it ideal for applications that require high levels of safety and reliability.
