2000w Emi Power Filter Module High Efficiency Dc Power Supply Filter Diy Audio FG05 Features:The straightening filter board can be used with the decoder and the power amplifier to filter the DC component of the power supply, eliminate the interference of the mains, etc., and effectively purify the power supplyThe DC-cracking circuit of the present invention eliminates and prevents the noise of the electrical appliance caused by the interference of the clutter and fluctuations in the commercial AC power supply by the flat-line SQ-type inductor.Eliminate and prevent DC components in the AC power supply of the mains by using diodes and capacitors to eliminate DC components, prevent the transformer from being magnetically saturated or quiescent current due to DC components.This circuit can suppress and eliminate AC interference components, bringing pure power to your audio.Flat line SQ inductors have the following advantages:1. Small volume, large current passing, unit current density is more than 1.3 times that of round copper wire;2. the straightening rectifier tube adopts the German law to seal the root and rectify,3. Close the magnetic circuit, the magnetic leakage is small, the EMI effect is ideal, and the conductive radiation effect is good, and the consistency is stable;4. High dielectric strength can extend the life of the power supply.Parameters:Straightening filter specification: 160*48*33MMPCB material technology: 1.6MM glass fiber double panel, black oil double-sided tin plating.Working voltage: AC110V-265VApplicable rated current: less than 2000WPacking List :1Pcs
