1. The use of high-quality materials, product quality is guaranteed 2. A level suitable for RFI filter DC circuit, through two 50A bridge stack and four 35V2200UF capacitors, filtering AC power in the DC component, to suppress the DC component trans suitable former generated by magnetic saturation or static current increase, and lead to humming 3. Differential mode filtering, two differential inductors, differential mode filtering of the AC power supply to suppress high and medium frequency interference 4.First level common mode filtering, through X2 capacitors and common mode inductors, combined into common mode filtering 5. Two common mode filtering, because of the use of two (also known as two sections) filtering, so the effect of noise filtering better. suitable for some users there are fast transient group pulse interference with a repetition frequency of several kilohertz, can play a suppression role Product parameters: Name: power filter suitable for audio amplifiers Input voltage: single-phase AC 110--250V Output voltage: single-phase AC 110--250V Load rated current: 10A Input port: three-wire 7.62 socket input Output port: 2-wire 7.62 socket output Colour:black Material:PCB+Components Due to different batches, there may be differences in product appearance and printed text, which not affect use Package Contents: 1 * Power filter Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
