WAudio AC Power Filter Power Conditioner – WAudio W-3900 Purifier with Surge Protector (Black)

The electrical grid can inject subtle noises into your setup, impacting the perceived clarity of audio and Video. The WAudio W-3900 acts as a dedicated buffer between the wall outlet and your gear, filtering disturbances and helping devices receive cleaner, more consistent power. While results vary by system, many users notice a quieter background and steadier performance across components when power is purified at the source.

Why clean power matters

• Power filtering targets a broad frequency range (2–100 MHz) to reduce interference that can affect audio signal and video brightness.
• Phase detect technology automatically checks the AC phase and ground connection for correct alignment with your gear.
• Built-in surge protection helps guard connected equipment from voltage events without creating additional noise.

Rugged design and flexible connectivity

• Heavy-duty metal casing with thick aluminum plates provides durable construction and efficient heat dissipation.
• Six hospital-grade filtered outlets plus four industrial-grade direct outlets offer versatile connectivity for multiple devices.
• Removable IEC power cord enables upgrading to premium cables if you choose to expand your system in the future.

Safe operation and practical use

The W-3900 monitors voltage irregularities and includes overload protection. If total current exceeds 15 A, outlets will shut off and can be reset to restore power. This helps maintain a stable environment for sensitive gear.
