Inrush Current Limiters (ICL)

An Inrush Current Limiter (ICL), such as the SL12 25002-B, is an electronic device designed to limit the amount of inrush current that can flow into a circuit when it is switched on. This device helps to protect electrical equipment from instantaneous overloading, and so prevents possible costly damage to the system.This type of ICL works by using the principle of impedance-based current limiting, in which the ICLs are inserted and placed in series between the terminal of the power source and its load. When the system is switched on, the ICLs start to reduce the inrush current and limit it to a safe level for the system. By limiting the inrush current, a large and sudden increase in temperature can be avoided, as well as arcing and sparking which can occur during the high currents drawn in during the inrush.The SL12 25002-B ICLs have a wide range of applications in many industries, such as in medical equipment, industrial machinery, and lighting systems. They are also widely used in automotive and aerospace applications. The SL12 25002-B provides high level protection in industrial, commercial and residential environments and is usually found in wall diodes, surge protectors, and uninterruptible power supplies.These ICLs are specifically designed to work in a variety of conditions and voltage levels, and have a wide temperature range from -40 to +90°C. They offer high inrush current limit levels and are able to control inrush current accurately and efficiently. Additionally, they feature an in-built ‘timed-out’ capability, which allows them to remain on for a specific duration after the inrush current has been cut off.The working principle of SL12 25002-B ICLs is based on the use of a thermistor, which is a temperature sensing component. The thermistor is connected in series with the load and senses the ambient temperature of the surrounding environment. When the inrush current passes through the thermistor, a voltage drop will occur and the load’s current will be limited. This eliminates overloading of the system, as the current will only beDrawing on these components limit current passing through the thermistor. The operation of the SL12 25002-B can be monitored from the LED indicator located on the board’s surface, which lights up when the current is within the limit range. If the ICL is working beyond this range, then the LED will blink to indicate that the limit has been exceeded. This ensures effective monitoring, allowing for quick responses to any changes in current flow.To sum up, the SL12 25002-B Inrush Current Limiter is a high-quality and efficient device. It is designed to limit the amount of inrush current that can flow into a system, while also providing reliable protection to the electrical equipment and preventing any potential damage to the system. These ICLs are multi-functional and offer a number of features, such as precise temperature sensing and user monitoring capability, making them ideal for use in a range of commercial and industrial applications.
