NAP-20-221-DXU power line filter modules are a group of products specifically designed for filtering high frequency noise in AC power lines. They are essential components for applications such as home entertainment, computers and appliances, and industrial equipment.

Application Field

NAP-20-221-DXU power line filter use in AC powerline applications, such as home entertainment, computers and appliances, and industrial equipment. It can effectively reduce the interference of high frequency noise generated by motors, relays, and other electrical components, so as to ensure the normal operation of the AC powerline system. It applies to both single phase and three phase applications, and is available in both IP20 and IP40 rated enclosures.

Working Principle

NAP-20-221-DXU power line filter module uses an inductive type EMI filter along with capacitors and a thermistor to achieve its filtering and surge protection capabilities. This EMI filter works by passing the desired frequency current from the AC power line through the inductors (also known as coils), which effectively generates an electromagnetic field, while the unwanted high frequency interference is blocked or absorbed by the inductors. At the same time, capacitors are used to ensure smooth current flow and further noise reduction. Furthermore, the thermistor provides surge protection against voltage fluctuations.

Conclusion

NAP-20-221-DXU power line filter modules are a great tool to reduce the impact of high frequency noise on AC power lines. They can securely and reliably provide a clean power supply to your home appliances and industrial equipment. While their basic working principle is relatively simple, they still provide an invaluable service to ensure the safe and efficient functioning of your power line.
