Inrush Current Limiters (ICL) are devices used to limit overcurrent phenomena from occurring during the initial power-up of an electrical system. This type of phenomenon is generally caused by the sudden inrush of current when a system is powered up for the first time, or after a brief period of power interruption. In some cases, this inrush current can be so high that it can damage electronic components in the system or interfere with the proper functioning of the power supply.

The SL15 2R509 Inrush Current Limiter (ICL) is designed to protect the systems from overcurrent during in-rush current. It functions by limiting the peak current in an electrical system to an acceptable level. It can be used in a wide variety of applications such as industrial and automotive.

The working principle of the SL15 2R509 Inrush Current Limiter (ICL) is that it limits current in phases when power is applied. It contains two resistors and a capacitor. These are connected in series to create a voltage divider circuit. During the inrush phase, the capacitor charges quickly through the high resistance provided by the resistor with the lower resistance value (Rx). This action ensures that the peak current is limited as the capacitor stores the current during this short time. After the inrush current is limited and the capacitor is fully charged, the voltage across it is higher than the voltage across the other resistor. This turns the circuit off thereby limiting the peak current.

The SL15 2R509 Inrush Current Limiter (ICL) can be employed in numerous applications such as power supplies, motor applications, and surge protection. It can be used in industrial applications such as those involving motor starters, transformers, and switchgear. Its capacitance and resistance values can be adjusted for this specific application. This device can also be used in battery charging systems, DC-DC converter, UPS, and emergency lighting applications.

The SL15 2R509 Inrush Current Limiter (ICL) is an efficient and cost-effective device for controlling and limiting the peak current in a variety of applications. It is capable of protecting electronic components from inrush current by limiting the peak current to an acceptable level. This helps to extend the life of electronic components as well as improve the reliability of the system.
