4A FCC EMI Power Filter Module 3 Stage High Frequency Audio Amplifiers Filter AC110V‑

Feature: 1. Good Noise Filtering Effect: EMI filter using three stage composite (1 stage differential mode and 2 stage common mode) circuit, because the use of three stage (also known as three sections) filtering, so the noise filtering effect is better. 2. Suppression: EMI filter for some users of the site there is a repetition frequency of several kilohertz of fast transient group pulse interference, can play a suppression role. 3. Matching Use: The EMI power filter module with the decoder (not included) use or amplifier (not included) use, can filter the power DC component, eliminate and suppress transformer hum, high frequency noise in the power supply. 4. Improve Sound Quality: EMI power filter module to purify the power supply, can significantly improve the amplifier sound quality, enhance the resolution and make the background quiet. 5. Connect Power Line Ground: EMI power filter input GND needs to be connected to the ground of the power line, while the actual situation can also be connected to the chassis shell. Specification: Item Type: EMI Power Filter For 3 Stage Audio Amplifiers Material: PCB Load Rated Current: 4A Input Port: 3 Wire 7.62 Socket Input Output Port: 2 Wire 7.62 Socket Output Design Features. 1. One stage differential mode filtering, two differential inductors, differential mode filtering of AC power supply, suppressing medium and high frequency interference 2. One stage common mode filtering, through X2 capacitor and common mode inductor, combined into common mode filtering. 3. 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. For some user sites there are repetitive frequency of several kilohertz The problem of fast transient group pulse interference of several kilohertz can play a suppressing role.
