The electricity network in our homes or workplaces is exposed to different interferences for instance electromagnetic interference (EMI) generated by appliances connected to the same network (refrigerators, air conditioners, computers etc.). These interferences are not only produced inside your house or office but by all appliances in your building or even outside it and can differ on the time of day or week when the traffic on the electrical network changes. All these interferences which we call noises can get into your AC power and interfere with your system. This “dirty” electricity can have a negative effect on performance of your audio-video system. WAudio power noise filter is a great way to limit the negative noises from your electricity and to isolate your system from the contaminated power and has a feature to indicate the correct power phase.Thanks to the W-3900 you will be able to enjoy a better quality of your audio and video equipment.The contaminated electricity has also a negative impact on internal circuits and power supplies of your equipment and because the W-3900 works as a buffer between the wall socket and your gear it will help to increase the longevity of connected components.Removable IEC type power cord gives an option to upgrade your system with a premium audiophile power cable in any time.Specification:Max Spike Volt: 3000VMax Surge Current (8x20s): 1000AMas Clamping Volt (8x20s): 470VNoise Filter: >-10dB (2~100MHz)AC Power Rating: 110~125V 50/60HzKit Contents:W-3900 power filter x 1 5ft power cord x 1 ## Features - 【PHASE DETECT】- Phase and the ground wire connection of AC source can be detected automatically. - 【OVERLOAD PROTECTION】- The sockets will be powered off when total current over 15A, press RESET button to restore power supply. - 【VOLTAGE PROTECTION】- Its circuit detects dangerous voltage irregularities and provides the highest level of surge & spike protection. - 【HEAVY DUTY DESIGN】- Metal casin with thickness aluminum plates, come with 6pcs hospital grade filtered outlets and 4pcs industrial grade direct outlets. - 【POWER CLEAN】- It ensures that all devices connected to W-3900 receive clean & filtered power, which reduces noise and ensures better sound and picture quality from amplifier, DJ equipment, home recording, projector, TV, computer, and other electronics. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08QZ8ZXF7 | | Amperage | 15 A | | Best Sellers Rank | #105,116 in Electronics ( See Top 100 in Electronics ) #756 in Surge Protectors | | Brand | WAudio | | Color | Black | | Connector Type | IEC, AC input | | Connector Type Used on Cable | IEC, AC input | | Customer Reviews | 4.3 out of 5 stars 578 Reviews | | Enclosure Material | Aluminum, Metal | | Item Dimensions | 16.54 x 5.12 x 3.54 inches | | Item Weight | 2.5 kg | | Manufacturer | Full Tat | | Material | Aluminum, Metal | | Mfr Part Number | W-3900 | | Model Number | W-3900 | | Number of Items | 1 | | Number of Packs | 1 | | Output Current | 1000 A | | UPC | 889743444490 | | Unit Count | 1 Count | ## Product Details - **Brand:** WAudio - **Color:** Black - **Connector Type:** IEC, AC input - **Item Weight:** 2.5 kg - **Material:** Aluminum, Metal ## Images ![AC Power Filter Power Conditioner - WAudio AC Power Purifier with Surge Protector, Black - Image 1](https://m.media-amazon.com/images/I/710em9EZqaS.jpg) ## Available Options This product comes in different **Color** options. ## Frequently Bought Together - AC Power Filter Power Conditioner - WAudio AC Power Purifier with Surge Protector, Black - Audiophile AC Power Cable - WAudio 10AWG HiFi Power Cord 3.3FT - WAudio 10 AWG Hi-End HiFi Audio Universal AC Power Cable Power Cord US Plug - 5FT (1.5M) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/262816594-ac-power-filter-power-conditioner-waudio-ac-power-purifier-surge](https://www.desertcart.sg/products/262816594-ac-power-filter-power-conditioner-waudio-ac-power-purifier-surge) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-11-06*
