Inrush current limiting devices, also known as ICLDs, are electronic devices that are designed to limit the high current that flows into a circuit when it is turned on. This high current, known as inrush current, can cause damage to the components of the circuit and can also lead to power surges.
Inrush current limiting devices work by using a combination of resistors, capacitors, and other electronic components to gradually allow the current to flow into the circuit. This gradual increase in current helps to prevent sudden spikes and surges that can damage the circuit.
The main benefit of using inrush current limiting devices is that they protect the components of a circuit from damage caused by high inrush currents. They also help to prevent power surges, which can be dangerous and can damage sensitive equipment.
Inrush current limiting devices are commonly used in electronic devices that have a high power demand, such as power supplies, motors, and transformers. They are also used in industrial equipment, medical equipment, and other applications where sudden power surges can be detrimental.
Yes, there are various types of inrush current limiting devices, including thermistors, NTC thermistors, and current limiting resistors. Each type has its own unique characteristics and is suitable for different applications. It is important to choose the right type of ICLD for a specific circuit to ensure proper protection.
