First level differential mode filtering with two differential inductors for differential mode filtering of AC power supply to suppress mid to high frequency interference<br/>2. The first level common mode filter is composed of X2 capacitors and common mode inductors to form a common mode filter.<br/>3. Three stage common mode filtering, due to the use of two-stage (also known as two-stage) filtering, has a better effect on filtering noise. It can effectively suppress the problem of rapid transient group pulse interference with a repetition frequency of several thousand hertz in certain user sites.<br/>4. The three-level composite (1-level differential mode+2-level common mode) EMI electromagnetic interference filter circuit, due to the use of three-level (also known as three-level) filtering, has a better filtering effect on noise.<br/>5. It can effectively suppress the problem of rapid transient group pulse interference with a repetition frequency of several thousand hertz in certain user sites.<br/>6.This module, when used in conjunction with a decoder or power amplifier, can filter the DC component of the power supply, eliminate and suppress transformer buzzing, high-frequency noise in the power supply, purify the power supply, significantly improve the sound quality of the power amplifier, enhance resolution, and make the background quiet.<br/>7.The input GND needs to be connected to the ground wire of the power cord, and can also be connected to the chassis casing, depending on the specific situation.<br/>Parameters:<br/>Name: Level 3 audio amplifier EMI power filter.<br/>Input voltage: single-phase AC 110-250V<br/>Output voltage: single-phase AC 110-250V<br/>Rated current of load: 4A / 10A / 20A<br/>Input port: 3-wire 7.62 socket input<br/>Output port: 2-wire 7.62 socket output<br/>Colour:black<br/>Material:PCB+Components<br/>Due to different batches, there may be differences in product appearance and printed text, which will not affect use<br/><br/>Package Contents:<br/>1 * EMI Power Filteres, there may be differences in product appearance and printed text, which will not affect use<br /><br />Package Contents:<br />1 * EMI Power Filter<br /><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.
