Inrush Current Limiters (ICL) are devices designed to control the amount of current that can be drawn from a power source. They are often used to protect sensitive electronic components from damage due to an excessive amount of current being drawn into the circuit.

The SG100 is a type of ICL designed to monitor inrush current levels and limit the current draw when it detects an abnormally high current draw. It works by detecting the inrush current the moment it begins to flow, and then rapidly activates a high-performance metal oxide varistor (MOV) which serves as a temporary short circuit. This immediately limits the current flow, preventing it from rising to dangerously high levels.

The use of the SG100 for inrush current limiting is not just limited to power supplies. It is also used in motor control, lighting, HVAC/R, healthcare equipment, and various electrical installations.

The working principle of the SG100 is fairly straightforward. When the power supply is connected to the device, the SG100 measures the inrush current. It will then activate its MOV when the current draw exceeds the designed threshold. When the MOV is activated, it will limit the current to a safe level, preventing any damage to the circuit.

The SG100 is capable of providing rapid and reliable protection against inrush current levels of up to 100A. This makes it ideal for protecting sensitive electronics from sudden and rapid increases in current draw. The SG100 is also easy to install and requires very little maintenance.

In addition to the SG100, there are other models of ICLs that are designed to provide protection against an extremely wide range of inrush current levels. Depending on the specific requirements of the application, the most appropriate model of ICL can be selected.

Inrush current limiters are a vital component in any power system. It is extremely important to ensure that the correct model of ICL is selected for the application in order to protect against damage to the circuit due to excessive inrush current levels. The SG100 is a great example of an effective inrush current limiter, providing reliable protection for up to 100A.
