Power Supply Filter Board Professional Compact Durable EMI Suppression Module for Power Amplifier 20A

Features 1、RFI Filter DC Circuit: A level of RFI filter DC circuit, through the two 50A bridge stack and four 35V 2200UF capacitors, filtering the DC component in the AC power supply, inhibit the DC component transformer generated by the magnetic saturation or static current increases, resulting in buzzing. 2、Used in Conjunction With: This module with the decoder or amplifier use, can filter the DC component of the power supply, eliminate and inhibit the transformer hum, high frequency noise in the power supply, purify the power supply, can significantly improve the sound quality of the amplifier, enhance the resolution and make the background quiet. 3、Differential Mode Filtering, First Level Common Mode Filtering: Differential mode filtering, two differential inductance, differential mode filtering of the AC power supply, inhibit high frequency interference. One stage common mode filtering, through the X2 capacitor and common mode inductor, the combination of common mode filtering. 4、Two Stage Common Mode Filtering: Adopt two stage common mode filtering, due to the use of two stage (also known as two section) filtering, so the effect of noise filtering is better. For some users on site there is a repetition frequency of several kilohertz of fast transient group pulse interference problems, can play a role in suppressing. 5、Three Stage Composite Filter Circuit: With three stage composite (1 differential mode and 2 common mode) EMI filter circuit, due to the use of three stage (also known as three section) filtering, so the effect of filtering noise is better. For some users on site presence of fast transient group pulse interference with a repetition frequency of several kilohertz, can play a role in suppressing the problem.
