EMI Electromagnetic Interference Filter Module DC 8A Power Purifier Power Filter Anti-Interference for Amplifier Module

1.Descriptions: It is a two-stage composite high-efficiency EMI filter.This module is used in conjunction with a decoder or power amplifier,which can filter the DC component of the power supply,high-frequency noise,eliminate mains interference,and purify the power supply,which can significantly improve the sound quality and resolution of the power amplifier.2.Feature: 1>.8A high current power supply 2>.Composite EMI filtering 3>.Strong anti-noise interference 4>.The shortest design of high-current lines,short paths,can withstand larger currents,and less interference to the outside world.3.Descriptions: 1>.Product Name:Two-stage Composite High-efficiency EMI Filter 2>.Input/Output Voltage:220V 3>.Supply Current:8A 4>.Load Power:1760W 5>.Capacitance:2200uF 6>.Work Temperature:-25℃~85℃ 7>.Work Humidity:5%~95%RH 8>.Size:100.5*38.5*34mm4.Power Purifier Circuit Introduction: 1>.The circuit consists of two parts,the first part is a DC filtering component circuit,and the second part is a two-stage composite EMI filter circuit. 2>.DC filtering component circuit:DC elimination circuit is used to eliminate the interference of AC components in AC AC 220V city power because of the DC components of inverter air conditioners,electronic switching power supplies,refrigerators,chargers and other home appliances.The DC-elimination circuit built with diodes and capacitors eliminates and prevents the DC components in the mains AC power supply,preventing the transformer from being magnetically saturated or increasing the static current due to the DC components. 3>.The internal circuit of the two-stage composite EMI filter uses two-stage (also called two-stage) filtering,so the effect of filtering noise is better.It can suppress the problem of fast transient group pulse interference with repetition frequency of several kilohertz in some user sites.5.Power Filtering Metho
