Power Line Filter Modules are created to suppress noise produced by electrical devices or do reduce the amount of noise entering a system from its environment. NAP-30-471-D is a series of 30A/471VAC Power Line Filter from Weidmuller which is currently being used in many industrial and enterprise applications. This article will discuss the application field and working principle of NAP-30-471-D power line filter.

Application Field of NAP-30-471-D

NAP-30-471-D power line filter is suitable for applications that requires power from 230VAC to 471VDC with a current rating of 30Amps. This module is quite popular among industrial applications due to its compact size and low running cost. It is commonly used in industrial and automation equipment, programmable logic controllers, industrial robots, server rooms, electronic and electrical equipment, and production line control systems.

Working Principle of NAP-30-471-D

The NAP-30-471-D power line filter is equipped with EMI or electromagnetic interference filters that are designed to filter out dirty power and disruptive interference signals and reduce the amount of power noise generated by a variety of electrical and electronic devices. The filter consists of two coils, a capacitor and a resistor connected in series, forming what is known as an LC filter. The coils wrap the electrical current and the capacitor helps to filter out the EMI signals. Finally, the resistor helps to reduce the current flow and stabilize the output voltage of the filter.

Additionally, the filter also comes with built-in thermal protection which helps to protect the filter from overloading and thermal damage. This helps to ensure that the filter works at its optimal level for a long period of time without any damage to the filter itself.

Conclusion

The NAP-30-471-D power line filter is a series of 30A/471VAC Power Line Filters from Weidmuller that offer premium-grade EMI protection and power noise reduction. It is suitable for applications that require power from 230VAC to 471VDC and the filter consists of two coils, a capacitor and a resistor connected in series. Additionally, the filter also comes with built-in thermal protection which helps to protect the filter from overloading and thermal damage.
