Power Line Filter Modules - NAH-20-471-D Application Field and Working PrinciplePower line filters are commonly used in a variety of electronic devices and systems, including medical equipment, telecom devices, and consumer electronics. They are also used in the design of industrial machinery and equipment. The NAH-20-471-D is a popular power line filter module suitable for use in such applications. Power line filters are designed to reduce electrical noise caused by switching devices and other electromagnetic interference sources. These filters are mainly used to protect sensitive electronic equipment from voltage transients, surges, and other disturbances.The NAH-20-471-D is a single-phase AC filter module that is used to filter out noise in circuit lines. It has an operating range of 110-240V AC, and a maximum current rating of 16A. The filter module is compatible with a wide range of AC frequencies, from 50 to 400Hz. The NAH-20-471-D can help reduce interference from nearby power lines, switch contacts, and other electromagnetic sources. It also helps reduce the potential for induced ac voltage buildup, and ensures a better electrical connection between the input and output components.The filter module is constructed from a dielectric substrate, which is designed to reduce EMI radiation, as well as provide a more reliable electrical connection. The substrate is essentially an insulating material that helps to reduce the transfer of EMI, while also providing a more reliable signal path. The NAH-20-471-D is also equipped with an inductor. The inductor is designed to reduce the level of transient voltage and current, which can be caused by contact arcing and contact closure on a power line. This helps to ensure that the circuit remains stable and avoids any excessive voltage spikes. The NAH-20-471-D also contains a capacitor. The capacitor helps to filter out AC transients, and helps to prevent any potentially damaging spikes or surges from reaching the connected electronic components. The capacitor also helps to reduce EMI by absorbing unwanted radio frequency energy from the power line.The NAH-20-471-D is also designed with multiple transistors. These transistors act as switches, which allow certain current paths to be switched on and off. This helps to control the flow of power, and ensures the circuit operates without any excessive power losses. The NAH-20-471-D is designed with a number of safety features. These features include thermal limiters, short circuit protection, and over-voltage shutdown protection. These safety features help to prevent damage to the filter, as well as the connected electronic components. In conclusion, the NAH-20-471-D is a popular power line filter module suitable for use in a wide range of applications. It is designed to reduce electrical noise caused by switching devices and other electromagnetic interference sources, as well as protect sensitive electronic equipment from voltage transients, surges, and other disturbances. The module is equipped with multiple safety features to protect both the filter and the connected electronic components.
