Power Line Filter Modules serve the same purpose as power supply filters, which are used to reduce the electrical interference caused by power cables and other external sources. They differ in technology and components from the traditional power supply filters, and are designed to reduce the effects of power surges, spikes, and other electromagnetic interference. This article will discuss the application field and working principle of FN258HV-16-29 filters.

FN258HV-16-29 power line filter modules are mainly used in industrial high voltage applications where low power input is required, and environmental conditions are more contaminants. Examples of these applications include electric motors, drives, lighting systems, ballasts, and combustion engines. These modules can also be used in furnaces, air-conditioning systems, building automation, heating systems, and lighting control.

The FN258HV-16-29 Modules have a working principle based on the attenuation of conducted interference by differential-mode filters and common-mode filters. The differential-mode filter provides low impedance differential-mode noise attenuation from power line conducted disturbances over a wide frequency range. Common-mode filters are used to reduce common-mode noise, which is mainly caused by capacitive coupling and mutual coupling between the power line and other radiating sources. The filters provide a certain level of balanced attenuation, which is determined by the design parameters of the module.

The FN258HV-16-29 Module is primarily designed for high voltage applications with input ranging from 77V to 500V. It is made up of three parts: a differential-mode network, a common-mode network, and a snap-on box. The differential and common-mode filter networks are designed to provide noise attenuation according to the requirements of the application. The snap-on box contains two fuses, one for the differential-mode and one for the common-mode filter. The filter modules are designed to meet the electromagnetic compatibility requirements of the EN 55011 and EN 55022.

FN258HV-16-29 power line filter modules are used in a wide range of industrial applications where the level of electrical interference needs to be reduced. The modules are designed to provide low impedance differential-mode noise attenuation and common-mode noise reduction. The snap-on box contains two fuses, to provide protection in the event of a power surge or spike. The filter modules meet the requirements of the EN 55011 and EN 55022.
