Features 1.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. 2.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. 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. 6.COMPOSITE: Three stage composite (one differential mode and two common mode) EMI filter circuits, due to the use of three stage filtering, so the noise filtering effect is better. specificationItem Type: Power Supply Filtering Board Material: PCB Input Voltage: Single Phase AC 110?250V Output Voltage: Single Phase AC 110?250V Load Rated Current: 4A Input Port: 3 Wire 7.62 Socket Input Output Port: 2 Wire 7.62 Socket Output Main Parts Selection: X2 Capacitor: Germany for Siemens 0.22UF 3PCS DC Elimination Capacitor: 35V 2200UF 4PCS, Diameter 16MM/0.6in DC Dissipative Bridge: 50A 1000V 2PCS Differential Mode Inductor: 47UH 2PCS Common Mode Inductor: 2 PCS Resistor: 1 PCS Socket: 7.62 2PIN and 3PIN 1PCS Each PackageList1 x PowerSupplyFilteringBoard NoteAll data are measured manually, and there are certain errors in the measurement results.
