110V 220V 4-Stage AC Power EMI Filter 2A 4A 10A 15A Common/Differential Mode Noise Suppressor Purifier Audio Amp DAC Amplifer

ZS-0024 AC Power EMC Filter - 4-Stage Common/Differential Mode EMI Suppression for Audio Amplifiers (High Current)This is a four-stage EMI electromagnetic interference filter designed for use with 110V-250V AC power lines. Primarily intended for audio amplifier power supplies, it effectively filters out high-frequency noise, functioning similarly to an isolation transformer to improve power quality.Important Note: This filter cleans high-frequency interference from the AC mains. It cannot resolve ground loop hum issues inherent to the amplifier's own wiring or system setup. No product in the world can universally "solve" ground loop hum.⚠️ SAFETY WARNING: This product involves HIGH VOLTAGE (110V-250V AC). Installation and handling must be performed by a qualified professional. Ensure proper insulation, NEVER operate on live circuits, and strictly observe electrical safety protocols to avoid risk of electric shock.Electrical Specifications:Input Voltage: Single-Phase AC 110V - 250VOutput Voltage: Single-Phase AC 110V - 250VRated Load Current: Available in 2A, 4A, 8A, 10A, and 15A models.Input Connector: 3-wire 7.62mm terminal block.Output Connector: 3-wire 7.62mm terminal block.Filter Function: Two-stage bidirectional differential-mode EMI filtering + Two-stage bidirectional common-mode EMI filtering.2A SIZE: 90X52X26MM4A SIZE: 90X52X32MM8A SIZE: 90X52X30MM10A SIZE: 90X52X28MM15A SIZE: 90X52X36MMDesign Features:Two-Stage Differential-Mode Filtering:Utilizes four differential-mode inductors to effectively suppress high-frequency differential-mode interference in the 5kHz - 20MHz range.Two-Stage Common-Mode Filtering:Combines X2 safety capacitors with common-mode inductors to form a robust common-mode filter network. The two-stage (dual-section) design provides superior noise attenuation and is particularly effective at suppressing fast transient group pulses with repetition frequencies in the kilohertz range, which are common in certain user environments.Applications:Ideal for purifying AC mains power in high-fidelity audio systems, power amplifiers, professional audio equipment, sensitive laboratory instruments, industrial control systems, and any application requiring suppression of conducted electromagnetic interference from the power line.
