Description <br> 1) Add an overvoltage protection circuit to prevent high voltage. <br> 2) Use a set of differential mode filters and two differential inductors to perform differential mode filtering on the AC power supply to suppress mid- and high-frequency interference. <br> 3) Three sets of common mode filters are combined by X2 capacitor and common mode inductor to form a common mode filter. Due to the use of three-level (also known as three-level) filtering, the effect of filtering out noise is better. It can effectively suppress the fast ient group pulse interference problem of some user sites with a repetition frequency of several thousand hertz. <br> Type:EMI filter <br> Style:EMC Safety Rules FCC <br> DIY Supplies:Electrical <br> EMI filter:AC 220v power supply <br> Four-stage (four-stage) EMI line filter <br> Input voltage:single-phase AC 110-250V <br> Output voltage:single-phase AC 110-250V <br> Input port:three-wire 7.62 socket input <br> Output port:three-wire 7.62 socket output <br> Function: <br> Overvoltage protection (surge protection) <br> Short circuit protection <br> Differential mode + common mode bidirectional EMI filtering to prevent interference <br> Extend the service life of electrical appliances and increase equipment stability <br> Load rated current:4A/8A/16A <br> Colour:As Shown <br> Material:ABS <br> <br> Package Contents: <br> 1 * filter <br> Only the above package content, other products are not included. <br> Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
