Inrush Current Limiters (ICL)

Inrush Current Limiters (ICL) are a type of electrical device that is designed to limit an excessive and damaging rush of current commonly referred to as inrush current. The simplest and most common type of ICL is the SL15 47003-A. This device works by monitoring and limiting the surge of electrical current when a power supply is turned on. This is done by limiting the inrush current to a predetermined safe level. This ensures that the power supply does not receive a surge of current that could damage it.

Application Field

The SL15 47003-A is primarily used in industrial applications. It can provide protection for any type of electrical equipment, such as pumps, transformers, motors, and generators. The device can also be used in other applications, such as surge protection for computer and communications networks, and in applications where an increased surge might occur from frequent cycling or frequent turning on and off of power supplies.

Working Principle

The SL15 47003-A works by controlling an inrush current according to a predetermined limit. This is achieved via a combination of electronic components, including resistors, capacitors, and transistors. When power is applied to the device, a magnetic field is created which acts as an energy store. It is this magnetic field that stores the energy needed to overcome the resistance of the electrical equipment being supplied, thus limiting the initial surge of current.

The device works by allowing only a predetermined amount of current through. This is done by using two resistors: a control resistor and a current limiting resistor. When power is applied to the ICL, the control resistor initially allows a high level of current to flow, which is then limited by the current-limiting resistor. This ensures that the receiving electrical equipment receives only the required amount of current, and prevents any possible damage that could be caused by inrush current.

The SL15 47003-A can be adjusted to suit specific applications and to tailor the response characteristics. It can also be used in applications where a voltage source device (VSD) is required. The ICL can be used as a VSD, providing a more efficient, safer, and more accurate voltage control.

Conclusion

The SL15 47003-A ICL is a versatile, cost-effective solution for limiting inrush current in industrial applications. Its adjustable characteristics make it suitable for a variety of applications, and its ability to act as a VSD provides increased accuracy and safety. With its combination of electronic components, the SL15 47003-A can provide reliable and effective protection against excessive current levels.
