Inrush Current Limiters (ICLs) are one of the most useful devices for controlling the power flow in an electrical system. They work by controlling the amount of current that enters the system while protecting it from any unexpected surges. One of the most popular examples of this kind of device is the SG120. The SG120 is a Inrush Current Limiter (ICL), used to prevent electrical systems from suffering from unexpected high power surges.

Application Field

The SG120 can be used in a wide range of applications, including medical, telecom, industrial and commercial equipment. It is used in applications where the inrush current can cause damage or overheat equipment if not monitored. It is ideal for applications such as medical imaging, telecommunications, security systems and power supplies.

The SG120 also has the ability to be used as a precision power monitor for low current applications. This makes it ideal for monitoring the power levels in complex devices such as MRI machines, ultrasound equipment and medical procedure lasers.

The SG120 is also used in industrial applications where inrush current can cause equipment failure or even explosions. The SG120 is used to monitor the power levels in power plants, nuclear reactors and oil refineries, protecting them from any potential failure.

Working Principle

The working principle of the SG120 is simple yet extremely effective. It uses an NTC thermistor to detect an increase in the current level, which then initiates a decrease in the current. This decrease in current is the result of the thermistor regulating the temperature of the current, thus controlling the amount of inrush current entering the system.

The SG120 is able to monitor the power levels in the system and adjust the current accordingly. This prevents any unexpected power surges from entering the system, which can cause damage or even danger. It also helps to regulate the power levels to prevent overheating in sensitive equipment.

The SG120 is capable of responding to changes in the power levels quickly, ensuring that the system is kept stable and functioning correctly. This helps to protect the system from unexpected electrical surges, while ensuring that the system’s power levels are always at their optimal levels.

Conclusion

The SG120 is an essential device for controlling the power flow in an electrical system. It can be used in a wide range of applications, and its effectiveness ensures that electrical systems remain stable and functioning correctly. Its working principle is simple and efficient, allowing it to control the inrush current while protecting the system from electrical surges.
