AC110--250V 4-20A Three-stage Audio Power Amplifier Power Filter Board Module
One common mode filtering, through X2 capacitor and common mode inductor, combined into common mode filtering.
Three-stage common-mode filtering, due to the use of two-stage (also known as two sections) filtering, so the effect of noise filtering better. It can suppress the problem of fast transient group pulse interference with a repetition frequency of several kilohertz at some user sites.
Three-stage composite (1-stage differential mode + 2-stage common mode) EMI EMI filter circuit, because of the use of three-stage (also known as three-section) filtering, so the effect of noise filtering better.
For some users there is a repetition frequency of several kilohertz fast transient group pulse interference problems, can play a suppression role.
This module with decoder use or amplifier use, can filter the power supply DC component, eliminate and suppress transformer hum, high-frequency noise in the power supply, purify the power supply, can significantly improve the amplifier sound quality, enhance the resolution and make the background quiet.
The input GND needs to be connected to the ground of the power line, but also then connected to the chassis shell, depending on the circumstances.
