Inrush current limiters (ICLs) are electronic components specifically designed to control the amount of current that can flow into an electronic device at startup. The SL22 30005-B is among the most efficient ICLs in the market and has an impressive range of applications and a reliable working principle.

Application

The SL22 30005-B is mainly used in high voltage circuits for controlling the inrush current levels during startup. It offers a reliable protection for devices such as industrial motor drives, thermo-vacuum pumps and transformers. Additionally, the SL22 30005-B can be used in relay and switchgear protection applications and is suitable for controlling the current of high power inductive circuits.

The SL22 30005-B has an impressive current rating of 100A and can withstand both ac and dc applications with up to 5kV peak voltage without any significant changes in the current rating. This means that it can be used to regulate inrush current levels in a variety of power circuits.

Working Principle

At the heart of the SL22 30005-B lies an innovative thermal management system which is based on the ‘PTC effect’. This allows the device to reduce the current levels during startup in order to protect the electrical circuit.

The PTC effect, or Positive Temperature Coefficient, is a phenomenon which occurs when the temperature of an electrical conductive material increases significantly. In the case of the SL22 30005-B, this is achieved by the device offloading up to 90% of the inrush current which occurs during startup. This in turn reduces the current load on the device and prevents any serious damage to the circuit.

Once the desired current level has been reached, the SL22 30005-B will then slowly return to its original state and allow for regular current levels to resume without any significant changes in the voltage. Additionally, this device also features a convenient heat-sink which effectively dissipates the heat caused by the offloading of excess current during startup.

Conclusion

Overall, the SL22 30005-B is an excellent example of how efficient and reliable inrush current limiters can be. It offers a reliable protection for high voltage applications while also featuring a convenient and efficient thermal management system. This makes it an ideal choice for those looking for a reliable way to control inrush currents in their power circuits without having to compromise on performance.
