CL-190

Inrush Current Limiters (ICL)

Inrush current limiters (ICL) are devices that help ensure a safe startup in an electrical system by limiting the inrush current. The CL-190 is a type of ICL which is widely used in many different applications.

Application

The CL-190 is most commonly used in automobiles and industrial machinery circuits, where it can be used to protect from inrush current caused by the mass production of devices such as solenoids and motors. It also has applications in audio systems, computers, power supplies, and other consumer electronics, where it can prevent damage from sudden and large electrical surges.

Working Principle

CL-190 ICLs work by introducing a controlled impedance in the circuit, which limits the maximum current that can flow. This impedance is achieved by using a resistor-capacitor (RC) circuit, which introduces a time delay before the full current can flow. Thus, during inrush events, the current is gradually increased from a low value, allowing the circuit to increase slowly, and preventing it from destroying any components.

The CL-190 can also be used to regulate inrush currents in switching power supplies. This is done by adjusting the resistance of the RC circuit. Since the CL-190 has an adjustable resistance, it is able to adjust the current during startup to match the specific needs of the circuit. This allows for a more efficient and safe operation.

Conclusion

The CL-190 ICL is a versatile device that can be used in many applications. It is able to provide a controlled impedance that limits inrush current, which helps ensure a safe startup for any system. By adjusting the resistance of the RC circuit, the CL-190 can also be used to regulate current in switching power supplies, making it an even more beneficial device.
