Inrush current limiters (ICLs) are used in various electronic applications to protect components from unexpected inrush current, and the SL18 2R508-B series is designed to provide effective protection from inrush current, making it an ideal candidate for use in a variety of applications and contexts. This article will discuss the application field and working principle of the SL18 2R508-B inrush current limiter.

Application Field of SL18 2R508-B

The SL18 2R508-B series inrush current limiter is widely used in many fields, such as AC motor starters, lighting, telecom, military, household appliances, medical equipment, automotive and ship electronic systems, security products, transportation systems, and so on. It is also widely used in many circuits and systems requiring inrush current protection (ICP). The SL18 2R508-B series is designed to provide a quick response inrush current protection for overvoltage source protection, protecting components in electronic circuits from being directly damaged by inrush current.

Working Principle of SL18 2R508-B

Inrush current limiters can prevent circuit overload and enhance the reliability and performance of power supplies and other equipment. The SL18 2R508-B inrush current limiter works on the principle of resistance-capacitor which balances the larger inrush current with a resistor. During normal operations, the SL18 2R508-B acts as an open circuit, allowing the full current to flow into the circuit. However, if the inrush current becomes too great, it is blocked and the current is diverted away. This is done by a resistor-capacitor combination, which functions as an open circuit at normal current levels and once the inrush current exceeds the set limit, the capacitance is discharged and the resistor is activated, thus diverting the inrush current away.

The SL18 2R508-B inrush current limiter is also designed to work at both AC and DC voltages, with an operating temperature ranging from -40°C to +125°C. It is also designed to protect sensitive components from momentary surges, high-frequency spikes, and inrush current, making it suitable for use in a range of applications. Moreover, it has a high tolerance for input voltage deviation, meaning it can be used in varied scenarios where alternating current or DC voltage is required.

Conclusion

The SL18 2R508-B series inrush current limiter is widely used in a variety of applications for inrush current protection, and provides effective protection from inrush current. It works on the principle of resistance-capacitor, which works to disperse and divert the inrush current in order to protect circuitry from damage. The SL18 2R508-B series is suitable for both AC and DC voltages and operates over a wide range of temperatures. In this way, the SL18 2R508-B series is an ideal candidate for use in protecting sensitive components from sudden surges and inrush current.
