Jrifedptry Power Filter Board Module Filter AC Mains Purification HiFi Audio Noise 10A Easy to Use

2). Differential mode filtering, two differential touch inductors, differential mode filtering of the AC power supply to suppress high and medium frequency interference 1). One stage for RFI filter DC circuit, through two 50A bridge stack and four 35V2200UF capacitors, filter the DC component of the AC power supply to suppress the magnetic saturation or static current increase due to the DC component transformer, resulting in . 3) First-level common-mode filtering, through X2 capacitors and common-mode inductors, combined into common-mode filtering. (4) Two common mode filtering, because of the use of two (also known as two sections) filtering, so the filtering of noise better. For some users there are fast transient group pulse interference with a repetition frequency of several kilohertz, can play a suppression role.
