Inrush Current Limiters (ICL)

Inrush current is a brief surge of high current that can occur when power is first applied to any electrical system, including an SL22 14005-B. It can cause problems ranging from power interruptions to fires, and anyone working with an electronic system should be aware of it. Inrush current limiters or ICLs are a type of semiconductor that helps prevent inrush current and makes power distribution safer and more efficient.

SL22 14005-B

The SL22 14005-B is a high voltage ICL that is specifically designed to block high inrush current, allowing it to be used safely in high voltage power applications. It is a two-terminal device with a self-contained resistor and diode. It has a built-in reverse bias diode that prevents reverse current flow, making it more reliable and reducing the risk of failure. The device consists of a semiconductor integrated circuit (IC) design, which limits the peak current on power-up to prevent damage to the system. The maximum load current is limited by the size of the resistor and the voltage rating. This ensures that the system remains within its rated operating levels without exceeding voltages or currents.

Working Principle

The working principle of the SL22 14005-B is based on the resistance and voltage values of the integrated circuit (IC). When the IC is turned on, the resistors create an internal voltage across the IC, which is detected by the internal voltage detection unit. This unit then limits the current through the device by creating an internal voltage drop across the resistors.This internal voltage drop limits the peak current to a safe level, allowing the system to start without the risk of damage. The maximum current that can be delivered is limited by the size of the resistors, which can be adjusted to meet the specific needs of the system.

Applications

The SL22 14005-B is designed for use in commercial and industrial applications requiring reliable, cost-effective, and efficient inrush current protection. It is ideal for use in high voltage applications such as LED lighting, industrial motor and generator operation, and transformers. It is also suitable for use in modern medical equipment, electrical charging systems, and other high powered applications. The device can help ensure safety in power systems and can provide energy savings due to its use of a self-contained resistor and diode. The device is also relatively inexpensive and easy to install, making it an attractive option for any application.

Conclusion

Inrush current is a potentially dangerous phenomenon that can cause permanent damage to an electrical system. The SL22 14005-B is a high voltage ICL designed to block this high inrush current and make power distribution safer and more efficient. Its features, such as self-contained resistor and diode, maximum load current limitation, and voltage detection unit limit the peak current and voltage to safe levels, and the device is ideal for commercial and industrial applications.
