High-quality materials ensure reliable performance. Features a multi-stage filtering design for audio amplifier power supplies: - First-stage RFI filtering for DC circuits, using two 50A bridge rectifiers and four 35V 2200µF capacitors to smooth AC ripple and reduce transformer hum caused by magnetic saturation or excessive static current. - Differential-mode filtering with two differential inductors to suppress high- and mid-frequency interference from the AC supply. - Primary common-mode filtering using X2-rated capacitors and a common-mode choke. - Secondary common-mode filtering stage (dual-stage design) for enhanced noise suppression, particularly effective against fast transient burst interference with repetition frequencies up to several kilohertz.
