Power Filter Board Audio Amplifier Supply Common Mode High Current Electromagnetic HiFi 20A

Power Filter Board Audio Amplifier Supply Common Mode High Current Electromagnetic HiFi 20A Description

1. First level differential mode filtering with two differential inductors for differential mode filtering of AC power supply to suppress mid to high frequency interference 2. The first level common mode filter is composed of X2 capacitors and common mode inductors to form a common mode filter. 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. 4. The three-level composite (1-level differential mode+2-level common mode) electromagnetic interference filter circuit, due to the use of three-level (also known as three-level) filtering, has a better filtering effect on noise. 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. 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. 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.
