Inrush current limiters (ICL) are devices that are designed to limit the amount of inrush current when an AC powered device is turned on. The SL05 10001 is a specific ICL designed to provide a reliable protection against inrush current surge.

The SL05 10001 is a thermistor-based inrush current limiter with operating temperature range of -20 to 70°C. It is designed to limit the peak current to typically 10 Amps and the maximum output current can be up to 100 Amps. The limiting characteristics are predetermined and depending on the resistance of the thermistor it provides a safe start-up behavior that is suitable for AC motors, transformers, amplifiers, and other AC powered devices.

The working principle of the SL05 10001 is based on the NTC-type thermistor which has a negative temperature coefficient. When the device is switched on, the thermistor is exposed to the full voltage that is applied to the load – this causes the thermistor to heat up quickly and therefore momentarily become a resistor that limits the amount of current passing through. As the thermistor gets heated up, its resistivity reduces and therefore the current continues to pass through the ICL until the load has been adequately charged. Once the load has been sufficiently charged, the thermistor cools down again and disconnects from the load.

In this way, the purpose of the inrush current limiter is fulfilled as the device limits the amount of inrush current that can be drawn by the AC powered device. The limitation protects the load from any type of damages that may occur due to the amount of inrush current. Furthermore, the SL05 10001 prevents any damage from overloading by limiting the maximum amount of current that can be drawn by the device.

Apart from the protection it offers to the device, the SL05 10001 also offers a number of advantages. Firstly, it is extremely easy to install as it just needs to be inserted into the power cord between the device and the power outlet. Secondly, the design of the SL05 10001 is compact in order to make it more convenient to use and versatile for different applications. Furthermore, it is also designed to minimize the power losses and therefore does not affect the overall performance of the device.

Thus, the SL05 10001 inrush current limiter is a perfect choice for ensuring the safe start-up and protection of AC powered devices. It allows for the current to flow in a controlled manner and prevents any potential damage to the device as a result of inrush current surge. Moreover, the compact design and easy installation make it the preferred choice for many applications.
