4A 8A 16A 4-level AC Power Supply EMI Filter 110V 220V Audio Electromagnetic Interference Filtering EMC Differential Common Mode

4A 8A 16A EMI Electromagnetic Interference Power Filter Four Stage EMC Differential mode Common mode Power Filtering For Audio Power AmplifierFeatures:1.With overvoltage protection circuit to prevent high voltage. 2.A set of differential mode filter and two pieces differential mode inductors are used to filter the AC power supply to suppress the interference of middle and high frequency. 3. Three sets of common-mode filtering, through the X2 capacitor and common mode inductor, combined into the common mode filter. Due to it is use of three stages filtering, so the filtering effect is more better. In view of the problem of rapid transient group pulse interference with repetition rate of several kilohertz in some users, it can play an inhibitory role. This module is used in conjunction with a decoder or power amplifier to filter the DC component of the power supply, eliminate and suppress the hum of the transformer, the high-frequency noise in the power supply, purify the power supply, and can significantly improve the sound quality of the power amplifier, enhance the resolution and make the background quiet. Parameters:Name: Four stage EMI power filter Input Voltage: AC 110V-250V(Max 250V) Output Voltage: AC 110V-250V Working Current: 4A/8A/16A Input/Output Interface: Three wire 7.62 wiring socket Function: Overvoltage protection (surge protection), Short circuit protection ; Differential mode+common mode, bidirectional EMI filtering to prevent interference, extend the service life of electrical appliances and increase equipment stability.
