Power Line Filter Modules

FN351H-8-29 is a power line filter module developed by Wenrun Electronics Co., Ltd. This filter module is well known for its excellent performance in filtering and AC line regulation, providing reliable and stable performance for AC line regulation.

Application Field

FN351H-8-29 is a small-volume filter module, with a wide range of applications, such as the regulation of AC lines for electrical appliances, telecommunication systems, power systems, and other industries. It is designed with unity power factor, a high rate of efficiency, and a wide operating temperature range and over-current protection. The module can be used for both continuous and ripple-proof applications, such as the regulation of electrical appliances, harmonic wave reduction, and over-voltage protection.

Working Principle

FN351H-8-29 adopts a filter structure consisting of an inductor, capacitor and resistor. The inductors and capacitors act as the filtering devices, and the resistor acts as the auxiliary resonance device for maintaining the stability of the system. The inductor also functions as a reactor and allows only frequencies which are below a certain value to pass through. The capacitor helps in absorbing the high frequency signals while allowing the low-frequency signals to pass. The resistor helps in controlling the frequency range by providing an effective impedance to the signal.

The overall power line filtering performance is improved by the three components, with a higher rate of effectiveness than just the inductor or the capacitor alone. The inductor and capacitor form an LC circuit which is tuned to a specific frequency in order to filter out any signal which fall outside the tuning frequency. This ensures that only the desired signal is passed on to the AC line.

The module has proved to be very effective in AC line regulation, providing a steady current, a reduced AC ripple, and improved electrical stability. It is also widely used in various industries for the reduction of harmonic distortion and over-voltage protection.

Conclusion

In conclusion, FN351H-8-29 is a highly effective power line filter module which can be used in a variety of applications, including AC line regulation, harmonic distortion reduction and over-voltage protection. The module is small-volume, and features a high rate of efficiency, unity power factor, and a wide operating temperature range. With its simple components, it provides a reliable and stable performance for AC line regulation.
