FN3258H-30-33 Application Field and Working Principle

FN3258H-30-33 is a type of power line filter which is used for filtering AC power power supplies. It is widely used in electrical and electronic devices because of its high efficiency, low vibration, and low noise. This article will focus on the application field and working principle of FN3258H-30-33.

Application Field of FN3258H-30-33

The FN3258H-30-33 power line filter is mainly used in precision electrical devices, communications devices, and audio equipment. It can effectively reduce high frequency noise on the power line and reduce disturbance to the normal operation of the device. It is also suitable for assembly line operation. In order to ensure the quality of the product, the power line filter is installed in the power supply line between the power grid and the device.

The FN3258H-30-33 power line filter has a harmonic range between 100Hz and 5kHz, reducing the amount of current and peak voltage on the power line, thereby reducing the level of EMI noise. The power filtering efficiency of the FN3258H-30-33 power line filter is between 95%-98%. It is suitable for the power line of 200VAC-240VAC and the frequency range of 50 Hz-60 Hz.

Working Principle of FN3258H-30-33

The FN3258H-30-33 power line filter is composed of inductor, capacitor, rectifier, voltage regulator, resistor, transient capacitor, etc. It works by using an inductor to block high frequency signals and a capacitor to prevent low frequency signals from entering the power line. When a high frequency signal exists, the inductor will absorb the current on the power line, attenuating the high frequency signal. When a low frequency signal exists, the capacitor will filter out low frequency components, thereby reducing the degree of interference on the power line.

In addition, the FN3258H-30-33 power line filter also has a DC compensation circuit. This circuit adjusts the output voltage of the filter to ensure that the electricity on the power line is clean and stable. In addition, a rectifier can reduce the level of AC ripple on the power line, further improving the filtering performance of the power line filter.

Conclusion

The FN3258H-30-33 power line filter module is a powerful device that is used to filter out high and low frequency signals on the power line. It is widely used in precision electronic devices, communications devices, and audio equipment. It has a wide harmonic range between 100 Hz and 5 kHz and a power filtering efficiency of 95%-98%. The working principle of the FN3258H-30-33 power line filter consists of an inductor, capacitor, rectifier, voltage regulator, resistor, transient capacitor, etc. This makes it an ideal choice for filtering power line noise.
