EMI DC Power Filter Board Power Purifier Noise Filtering Impurity AC

EMI DC Power Filter Board Power Purifier Noise Filtering Impurity AC 220V

Descrtion:

In the munical power grid, the wave pattern of AC power is ly symmetrical in the upper half wave and the lower half wave, but because thousands of households share the same power grid, various electrical appliances are used in parallel,This will cause an unbalanced voltage drop in the upper or lower half of the alternating current to produce a certain DC component. For high-power s, the primary resistance is very low, generally only a few tenths to a few s resistance, especially the toroidal core has no magnetic separation of the entire str of steel sheets. A very low voltage can reach the magnetic saturation of the core, which will not only increase its own power consumption, increase temperature rise, and cause operating noise Increase, and even cause abnormal magnetic saturation of the core.

This product is connected in series with AC220V live wire. A 50A high-current rectifier bridge is used in series to eliminate the DC component more thoroughly. It can effectively eliminate the abnormal sound of the caused by the DC component in the power grid (especially the sound of the ring bull ).
