Features 1.USE WITH: Power supply filtering board with decoder use or amplifier use, can filter the power supply DC component, eliminate and suppress transformer hum, high frequency noise in the power supply. 2.POWER SUPPLY FILTERING: EMI power supply filter board to purify the power supply, can significantly improve the sound quality of the amplifier, improve the resolution and make the background quiet. 3.RFI FILTERING DC CIRCUIT: Through two 50A bridge stack and four 35V2200UF capacitors, filter the DC component of the AC power supply, to suppress the DC component transformer generated by magnetic saturation or static current increase. 4.DIFFERENTIAL MODE FILTERING: Two differential mode inductors, differential mode filtering of the AC power supply to suppress high and medium frequency interference. 5.COMMON MODE FILTERING: One stage common mode filtering is combined by X2 capacitor and common mode inductor. Two stage common mode filtering is more effective in filtering out noise due to the use of two stage filtering. specificationItem Type: Power Supply Filtering Board_x000D_ Material: PCB_x000D_ Input Voltage: Single Phase AC 110-250V_x000D_ Output Voltage: Single Phase AC 110-250V_x000D_ Input Port: 3 Wire 7.62 Socket_x000D_ Output Port: 2 Wire 7.62 Socket PackageList1 x PowerSupplyFilteringBoard
