Introduction of Inrush Current Limiters (ICL)

Inrush current limiters (ICL) are one of the most effective methods of controlling the high inrush current during the start-up of electrical equipment. ICLs are used to limit the current inrush at a certain current level, thereby giving the input power supply time to start up properly, while ensuring that the input power supply can handle the load current. ICLs can be used in a wide range of applications such as power supplies, DC-DC converters, AC-DC power supplies, and even in high voltage systems.

SG307 Inrush Current Limiter

The SG307 is a 3-phase inrush current limiter designed to be used in high voltage systems. It has a current rating up to 200A and a voltage rating up to 600V AC. It is designed to provide a reliable and precise current limiting and is capable of limiting the inrush current during the start-up of a system. It is also designed to reduce the power consumption of the system during the start-up. It can be used in electronic control systems, DC converters, variable speed drives, and in many types of high voltage systems.

Working Principle of SG307

The working principle of the SG307 inrush current limiter is based on the principle of electromechanical energy conversion. The device utilizes a combination of electromagnetism and magnetism to limit the flow of current to a certain level. During the start-up of a system, the electromagnet produces a magnetic field in front of the core, which attracts and absorbs the high inrush current coming from the input power supply. This limits the flow of current into the device. At the same time, the alternating current in the device is converted to electromagnetic energy, which is used to reduce the current through the device and ensure that the current does not exceed the safe limit. The SG307 inrush current limiter is capable of regulating the current to protect the input power supply and the other components of the system.

Applications of SG307

The SG307 inrush current limiter is applicable in a variety of electronic systems including DC converters, variable speed drives, AC-DC power supplies, and other heavy-duty applications. In addition, it can also be used to provide protection for high voltage systems by limiting the inrush current during the start-up. It is also capable of providing protection for motors, transformers, and other heavy-duty systems. Finally, the SG307 inrush current limiter is also effective in reducing the power consumption of the system during the start-up. It is capable of reducing the power consumption of the system by up to 35%.

Conclusion

In conclusion, the SG307 inrush current limiter is an effective device designed to limit the excessive inrush current during the start-up of an electrical system. It is applicable to a wide range of systems, and can help reduce the power consumption of the system during the start-up. Furthermore, the SG307 inrush current limiter is able to provide protection for the input power supply and other components by preventing the current from exceeding the safe limit.
