Inrush Current Limiters (ICLs) are devices used to limit the inrush current in an electrical circuit, with the goal to reduce power consumption of the circuit, reduce stress on components and increase the circuit\'s overall efficiency. One of the most commonly used ICLs is the SL12 1R308-B. This article will discuss the application fields and working principle of the SL12 1R308-B.
The SL12 1R308-B is a standard ICL device designed for low-voltage and current electronic applications. It is composed of two resistors which are connected in parallel. The resistor\'s resistance is adjustable, allowing for fine-tuning the limiting current. In addition, the SL12 1R308-B has a built-in thermal protector, which allows it to work in extreme temperatures. The SL12 1R308-B is also shockproof and corrosion-resistant, making it ideal for industrial applications.
The SL12 1R308-B can be used in a wide range of electrical applications, such as electric motors, pumps, fans, HVAC systems, equipment and industrial machinery. It is used to reduce the inrush current during motor start-up and also to extend the life of the motor by reducing the amount of energy required to start-up the motor. In addition, the SL12 1R308-B can be used in computers and microprocessor-controlled systems to reduce the startup surge current, which can otherwise prevent the system from operating correctly.
The working principle of the SL12 1R308-B is simple and can be broken down into two stages. Firstly, upon activation, the two resistors within the SL12 1R308-B automatically limit the inrush current. This is done by connecting one end of the resistor across the power source and the other end across the load. As the current flows through the resistors, it experiences a varying degree of resistance. This results in a gradual increase in the limiting current, rather than a sudden surge.
The next stage involves the thermal protector. This is triggered when the limiting current exceeds a set value. When this occurs, the two resistors within the SL12 1R308-B immediately limit the current, thus preventing the flow of the excessive current. The thermal protector also helps to protect the circuit from thermal overload. It prevents the SL12 1R308-B from being damaged due to excessive heat.
The SL12 1R308-B is a powerful and reliable device for protecting electrical circuits from inrush current, overheating and overload. It is a popular choice for industrial and commercial applications, due to its adjustable resistance and built-in thermal protector. This makes it ideal for protecting motors, pumps, fans, HVAC systems, equipment and industrial machinery, as well as computers and microprocessor-controlled systems. As such, the SL12 1R308-B is an invaluable asset to any electrical system.
