EMI Power Filter Board for Audio, AC 110V-250V, Excellent Noise Filtering

This EMI filter features a 3-stage design, with 1 stage for differential mode filtering and 2 stages for common mode filtering. This configuration enhances the noise filtering performance of the filter. Additionally, the filter has a good suppress function, effectively mitigating the issue of rapid transient group pulse interference with a high repetition frequency in specific user sites.

Moreover, this module serves multiple functions when used in conjunction with a decoder or power amplifier. It can filter the DC component of the power supply, eliminate and suppress high-frequency noise in the transformer and power supply, improve the sound quality of the amplifier, enhance resolution, and create a quieter background.

Connecting the filter is easy, as the input GND should be connected to the ground wire of the power cord and can also be connected to the chassis casing if desired. The filtering board is equipped with reliable components, ensuring high reliability and stability during operation.

Specification: - Item Type: EMI Filter - Material: PCB - Input Voltage: Single phase AC 110-250V - Output Voltage: Single phase AC 110-250V - Load Rated Current: 20A - Input Port: 3 wire 7.62 socket input - Output Port: 2 wire 7.62 socket output

Design Features: 1. First-stage differential mode filtering: Two differential inductors effectively filter the AC power supply, suppressing mid to high-frequency interference. 2. Second-stage common mode filtering: Combined with X2 capacitors and common mode inductors, this stage serves as a common mode filter. 3. Three-stage common mode filtering: The two-stage filtering setup greatly improves the noise filtering effectiveness. It successfully suppresses rapid transient group pulse interference with a repetition frequency of several thousand in certain user sites.
