Inrush Current Limiters (ICL)

Inrush current limiters (ICLs) are circuit development devices that protect a power supply, circuit, or other system components by limiting inrush current to protect the equipment. The inrush current trigger inrush current limiters are designed to limit the amount of current that is allowed to be supplied to the equipment when energizing power supplies, circuits, or other system components.

The SL32 0R530 is a type of ICL designed to help protect sensitive electronic equipment from large inrush current surges. It is a completely passive unit with no external switching components required. This allows for simple installation, as well as reduced component size and cost. The device operates regardless of the load environment, and is capable of limiting inrush currents up to 100A.

Application Field

The SL32 0R530 is typically used with sensitive electronic equipment in a variety of industrial, commercial, and consumer applications. These applications include: telecommunications systems, home entertainment systems, data centers, industrial machinery, lighting controls, anti-theft systems, embedded systems, automotive and avionics systems, medical equipment, and consumer appliances.

Working Principle

The SL32 0 R530 works on the principle of using an NTC thermistor to control inrush current. The thermistor is connected between both legs of the AC mains, and its resistance value decreases with temperature. During initial power up, the thermistor is cold and therefore has a high resistance. This resistance limits current flow and therefore prevents excessive inrush current from entering the system.

As the current increases, the thermistor starts to heat up. As the temperature of the thermistor increases, its resistance value decreases in a predictable manner. This allows it to control the inrush current so that even high current surges are limited, thus protecting the system components from damage.

The SL32 0R530 also features a wide operating temperature range of -40℃ to +85℃, ensuring reliable and stable inrush current control over a wide range of environmental conditions.

Conclusion

The SL32 0R530 is a simple and effective inrush current limiter that is capable of protecting sensitive electronic equipment from large inrush current surges. It is easy to install and provides reliable protection over a wide temperature range. This makes it the ideal choice for many industrial, commercial, and consumer applications.
