Inrush Current Limiters (ICL) - SL15 80002-A Application Field and Working Principle

Inrush current limiters (ICLs) are a type of thermal device used for limiting the inrush current and transient over-voltage of systems when an AC power supply is switched on. ICLs are an essential part of power supply systems in many applications, such as industrial, home, commercial, and biomedical. The SL15 80002-A is a model of ICL manufactured by Schneider Electric, and this model is specifically designed for a wide range of applications.

Application Fields

The SL15 80002-A is an ideal choice for ICLs in a variety of applications due to its wide range of features and functions. It can be used in a variety of settings such as industrial, medical, professional lighting, and commercial air-conditioning. It is also suitable for power supplies of various types, such as LED lighting, air-conditioning, and other appliance power supplies. In addition, it can be used in mechanical equipment that has large inrush currents.

Working Principle

The SL15 80002-A is equipped with a thermal switch that is triggered by an inrush current exceeding the design rating of the device. The thermal switch allows the ICL to limit the inrush current and prevent any transient over-voltage. Once the current passes through the thermal switch, the ICL will go into protection mode and will start to reduce the voltage until it is within the acceptable levels. This will also reset the thermal switch, allowing the ICL to start working again.

The SL15 80002-A’s protection mode also includes a control circuit, which monitors the voltage and will cycle on and off depending on the situation. This allows the ICL to react to any changes in the power supply that may be caused by external factors or unexpected surges. When the voltage exceeds the preset levels, the control circuit will cause the ICL to open the circuit, reducing the voltage below the set levels and preventing any further harm to the system.

Advantages of the SL15 80002-A

The SL15 80002-A offers a wide range of advantages for applications that require an efficient and reliable ICL. These include a small size and a light weight, allowing for easy installation. It also provides high surge current protection, making it suitable for applications that require heavy duty current protection. In addition, it offers a fast activation time, making it suitable for applications that require a quick response, and a long life, which ensures durability.

Conclusion

The SL15 80002-A ICL from Schneider Electric is an ideal choice for applications requiring high surge current protection and fast response. It is suitable for a wide range of applications and provides a reliable and efficient way to protect systems from transient over-voltage. Its thermal switch limits the inrush current while its control circuit monitors the voltage, ensuring that the system remains within the preset levels.
