Inrush Current Limiters (ICL) are important components when it comes to power systems operating safely and efficiently. They provide a controlled and reliable supply of current on start-up, which prevents circuit breakers or fuses from tripping if there is an overload. By controlling the startup time, they also help reduce power consumption, as well as prevent excessive current flow. The SL12 5R004-A is a typical example of an ICL. This article will discuss the application field and working principle of the SL12 5R004-A.

The SL12 5R004-A is an inrush current limiting device specifically designed for high current applications such as motors, ballasts, and welding machinery. It is rated for currents up to 100A, and is suitable for almost all types of equipment. It has a built-in thermal switch which ensures that the current is maintained within a safe range by preventing overloads. The device also has a built-in noise filter, which reduces the level of electromagnetic interference. Furthermore, the SL12 5R004-A has an essentially negligible voltage drop, meaning that it can be used in low voltage applications as well.

The working principle of the SL12 5R004-A is fairly straightforward. When the power supply is turned on, excess inrush current is generated, which can cause surges and overloads. The device contains a set of resistors and coils connected in series which act as a current shunt, and limit the amount of current that can flow into the circuit. When the current reaches the set limit, the current is diverted, reducing the inrush current to a safe level.

In addition, the SL12 5R004-A has several additional features and benefits. It is designed for high cycle operation, meaning that it can withstand multiple on-off cycles without failure. It is also designed for precise current protection, which ensures that the exact specified current is maintained. The device also has a wide operating temperature range, which means that it can be used in a variety of environments, from hot to cold. Finally, the SL12 5R004-A is UL-certified, meaning that it meets stringent safety and quality standards.

In summary, the SL12 5R004-A is an inrush current limiting device designed for high current applications such as motors, ballasts, and welding machinery. It is designed to limit the amount of inrush current, preventing circuit breakers or fuses from tripping. Furthermore, it has additional features such as an essentially negligible voltage drop, built-in thermal switch, noise filter, high cycle operation, and precise current protection. Finally, the device is UL-certified, providing peace of mind and assurance that the device is safe and reliable.
