Feature: 1. 3 STAGE FILTERING: A three stage composite (1 stage differential mode and 2 stage common mode) EMI electromagnetic interference filter circuit. Due to the use of three stage filtering, the effect of filtering noise is better. 2. ANTI INTERFERENCE: EMI filter can suppress the problem of rapid transient group pulse interference with a repetition frequency of several thousand hz in certain user sites. 3. MAIN PURPOSE: This module can be used in conjunction with a decoder or power amplifier to 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. 4. EASY TO USE: The input GND needs to be connected to the ground wire of the power cord, and can also be connected to the chassis shell, depending on the specific situation. 5. IDEAL REPLACEMENT: Wonderful replacement for the old and damaged parts, fine workmanship, attention to details, helps you improve the working efficiency! Specification: Item Type: EMI Power Filter Material: PCB Input Voltage: Single phase AC 110-250V Output Voltage: Single phase AC 110-250V Rated Current of Load: 10A Input Port: 3 wire 7.62 socket input Output Port: 2 wire 7.62 socket output Design Features: 1) First stage 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 stage common mode filter is composed of X2 capacitors and common mode inductors to form a common mode filter. 3) The three stage common mode filtering has a better filtering effect due to the use of two stage filtering. It can effectively suppress the problem of rapid transient group pulse interference with a repetition frequency of several thousand hz in certain user sites. . Package List: 1 x EMI Power Filter
