Inrush Current Limiters (ICLs) are a type of device used to limit high inrush currents that can occur when power is applied to an electrical system. There are many different types of ICLs, but one of the most common and widely used is the CL-190AB. This particular type of ICL is made of two thermistors: one for voltage regulation and one for current limiting protection.

The CL-190AB is designed to provide inrush current protection for AC circuit protection devices such as controllers, motors, switches, and PLCs. This ICL is rated for 10A and has a nominal voltage of 250VAC. It is relatively compact and lightweight, making it ideal for a wide variety of applications.

The working principle of the CL-190AB is based on its two components, the thermistors. A thermistor is a type of variable resistor, made of a material that changes its resistance when its temperature changes. In this case, the positive thermistor, upon power-up, will draw in more current compared to a negative thermistor. This inrush current will, in turn, cause the thermistor to build up heat quickly, which reduces its resistance and limits the current.

The CL-190AB can be used in a multitude of applications, including motor circuit protection, power inverter protection, automotive power supply protection, EMC filter protection, electrical heater protection, vacuum technology power supply, LED lighting protection, power management control, and more.

The CL-190AB is widely used because of its combination of high-performance capability, low power consumption, high reliability, and high efficiency. It is also relatively easy to install and can be adapted to fit into a wide range of applications. The device provides an excellent degree of thermal stability, which helps keep the circuit’s components at the desired temperature range for optimal operation. It is also capable of automatically balancing the flow of current, which helps to reduce power losses and extend the service life of the system components.

The CL-190AB is an excellent choice for applications requiring fast inrush current protection. It is reliable, efficient, and easy to install, making it a popular choice for a wide range of applications. The device is also relatively affordable and provides an excellent degree of thermal stability, making it an ideal choice for a variety of electrical systems.
