Power Line Filter Modules are an important part of any electrical system. They provide the necessary protection from containing interference and protecting equipment. Among the power line filter modules, NAH-30-331 is particularly popular. The article provides an introduction to the application field and working principle of NAH-30-331.

NAH-30-331, as a kind of power line filter module, is usually used to reduce impulse noise, reduce harmonic noise, suppress RFI (Radio Frequency Interference) energy, and provide plain power to the electrical equipment. As a result, it can not only improve the power quality but also increase the reliable performance of the electrical system.

The application field for NAH-30-331 includes any area that needs to protect the operation of electrical equipment from interference, such as industrial control, lift, electric locomotive, elevators, health care equipment, office equipment, process control, instrumentation, etc. The wide range of application fields indicates the reliability and effectiveness of this power line filter module. Moreover, the module’s continuous current for an AC circuit is 50A, DC circuit is 12A, and it supports 300v and 600v.

In terms of its working principle, NAH-30-331 works mainly through capacitive filtering, which is an effective method to filter power line interference, digital interference, sun radiation interference, lightning interference, and static interference. Moreover, when NAH-30-331 is in use, its capacitive filtering can attenuate noises in both low and high-frequency fields.

Thanks to its excellent capacitive filtering ability, NAH-30-331 can filter 80 ~ 100dB in the range of 1MHz to 30MHz while its rated voltage varies from 250Vac/ 300Vdc to 600Vdc. Its filtering effect is also very efficient, achieving no less than 4 dB when it is within the rated current range. Also, in terms of its design, the NAH-30-331 is made with an all-enclosed structure with integral soldering and can be customized according to customers’ needs in terms of the configuration of different terminals, the number of filtering modes and power levels.

In summary, NAH-30-331 is a power line filter module which is widely used to reduce impulse noise, reduce harmonic noise, suppress RFI energy, and provide plain power to the electrical equipment. It has a wide range of application fields, and its working principle is based on efficient capacitive filtering, ensuring high-performance performance, reliability and efficiency. It is a highly recommended power line filter module choice.
