Inrush Current Limiters (ICL)

Inrush current limiters, also known as inrush current limiters, are devices that limit surge currents that occur when power is applied to a system. These devices are used to regulate the onset of large currents that may cause damage to components, such as transistors, fuses, and circuit breakers. Inrush current limiters can also be used to limit the amount of inrush current that can enter a system. The AS35 2R035 is a popular inrush current limiter used in many applications, and this article will discuss the application fields and working principle of this device.

Application Fields

The AS35 2R035 is a thermal device used to prevent inrush currents, or large currents flowing when power is applied to a system. This device is able to limit very high inrush currents, and has a wide range of applications in various industries. It can be used in power supplies, motors, transformers, UPS systems, solenoids, inverters, and other electronic devices. Additionally, it can be used in automotive applications, such as fuel injectors, spark plugs, and starter motors.

The AS35 2R035 is also used in audio-visual equipment, such as amplifiers, video players, recorders, and other electronic devices. It can also be used in telecommunications systems, data centers, and other areas where there is a need to protect against large inrush currents. Additionally, it can be used in laboratory equipment, medical equipment, and other sensitive electronic devices.

Working Principle

The AS35 2R035 inrush current limiter works according to the concept of thermal inertia. It is made up of three main components: a resistor, a thermistor, and a control circuit. When power is applied to the system, a large current surge passes through the resistor. This creates a temperature increase, which is detected by the thermistor. The thermistor then sends a signal to the control circuit, which triggers the inrush current limiter.

The control circuit then switches on the resistor, which limits the inrush current. The resistor also serves as a heat sink, dissipating the heat generated by the inrush current. This limits the amount of heat that is conducted to other components in the system. Once the temperature rises to a certain level, the control circuit signals to switch off the resistor, allowing the current to continue flowing.

The resistance of the resistor is adjustable, allowing for different levels of inrush current limiting. Additionally, the activation level can be adjusted, so that the inrush current limiter can act only when a certain level of inrush current is exceeded. This allows for greater flexibility in the use of the device, and ensures that the highest levels of safety are met.

Conclusion

The AS35 2R035 is a popular inrush current limiter used in a variety of applications. It is designed to protect circuit components from large inrush currents by limiting the amount of current that can enter the system. The device makes use of thermal inertia to detect inrush currents and then activate a resistor to limit the current. The adjustable resistance and activation levels allow for greater flexibility in the use of the device, ensuring that the highest levels of safety are met.
