Power Line Filter Modules are an important part of many electronic equipment and are essential components for meeting international EMI (Electro Magnetic Interference) and RFI (Radio Frequency Interference) standards. The NAM-30-331-D is a UL, CUL, ES, and RoHS approved power line filter module for AC/DC applications up to 250VAC (277VAC Rated). It is designed as a low-current-carrying module to reduce radiated and conducted EMI noise in electronic equipment and has a total current rating of 30A, and it fits in two thirds of a DIN-sized reel.The NAM-30-331-D is used in industrial applications such as switching power supplies, industrial controlled motors, machine tools, drives, and a number of other applications. It is designed to reduce conducted and radiated EMI from the power line by providing a low-resistance connection between the power line and the load. The filter is composed of high-quality ferrite cores and inductive components, which create a low stress path for EMI and RFI to pass through.The NAM-30-331-D has an input voltage range from 12 to 250 VAC/DC and an output voltage range from 16 to 250 VAC/DC. It also features a transient protection rating of 6kV/1.8kV (30A) and a low insertion loss. This power line filter module has an integrated LCD/LED panel with a voltage selection switch and LED indicator. It is designed to allow for easy installation and has a DIN-mountable mounting base.In terms of working principle, the filter acts as an impedance barrier between the source and the load, to reduce common-mode and differential-mode noise in the power line. Its three-stage structure consists of an LC filter network, an impedance transformer, and an EMI filter. The LC filter network is composed of two parts; one is used to suppress common-mode noise and the other is used to suppress differential-mode interference. The impedance transformer is used to convert the high impedance created by the LC filter network to reduce the load on the EMI filters.The EMI filter attenuates noise at frequencies up to 100MHz and is able to reduce both common-mode and differential-mode interference. It is also designed with solid state components and has built-in current and temperature overload protectors to increase its performance and reliability. The NAM-30-331-D is widely used in a variety of industrial applications as a power line filter because it is cost effective, easy to install, and has a low insertion loss. It also reduces conducted and radiated EMI noise from the power line, which is essential for meeting international EMI and RFI standards. This makes it an ideal solution for high-reliability industrial applications.
