Power Filter Filtering Board Audio Amplifier Power Supply Filter Common Mode High Current

1. A first-level differential mode filter with two differential inductors is used for the differential mode filter of AC power supply to suppress middle and high frequency interference2. The first-stage common-mode filter consists of an X2 capacitor and a common-mode inductor.3. Three-level common-mode filtering, due to the use of two-stage (also known as two-stage) filtering, the filtering effect on noise is better. It can effectively suppress the problem of fast transient group pulse interference with a repetition rate of several thousand in some user sites.4. Three-level composite (1 level differential mode +2 level common mode)EMI EMI interference filtering circuit, because of the use of three-level (also known as three-level) filtering, the noise has a good filtering effect.5. It can effectively suppress the problem of fast transient group pulse interference with a repetition rate of several thousand in some user sites.Input voltage: single-phase AC 110-250VOutput voltage: single-phase AC 110-250VLoad rated current: 4A-20AInput interface: 3-wire 7.62 socket inputOutput interface: 2-wire 7.62 socket outputSelection of major componentsX2 capacitor: German West Gate 0.22UF 3PCSY2 capacitance :275V 3300PF 2PCSDifferential mode inductance :47u2pcsCommon mode inductance :2pcsPacking list: Audio Amplifier *1 (excluding other exhibits)Notes:Due to manual measurement, please allow an error of 2-3 cm.The actual color may be slightly different from the picture due to different lighting.Chip protection, overvoltage undervoltage overheat DC short circuit detection.
