With the popularization of smart homes and the increasing number of household appliances, the problem of electromagnetic interference in household electricity environment is becoming more and more prominent. The start and stop of high-power appliances such as refrigerators and air conditioners, and the high-frequency operation of routers and microwave ovens will all produce clutter interference, which will lead to problems such as flickering TV pictures, network signal jamming, and noise in audio. Shanghai Fengchuang Industrial Co., Ltd., with its deep accumulation in the field of filtering technology, launched the first socket filter, which provides a brand-new solution for household power interference control with plug-and-play convenient design, so that ordinary families can easily enjoy a purer power environment.
As a national high-tech enterprise deeply involved in the field of electrical equipment, Shanghai Fengchuang Industrial Co., Ltd. has always been user-oriented. Previously, its "Fengyun-Fonyun" brand industrial-grade filter has been widely used in factories, hospitals and other scenes, and won market recognition with its excellent anti-interference performance. The R&D team found that household users have the same urgent need to control power interference, but the traditional industrial filter has some problems such as complex installation, too large volume and professional operation, which makes it difficult to adapt to family scenes. To this end, Fengchuang has launched this socket filter designed for home after 18 months of technical research according to the characteristics of household electricity consumption.
Fengchuang socket filter continues the core advantages of industrial products in technology, and optimizes the adaptation of home scenes. Its interior adopts a "mini-multistage filter" structure, which integrates a common mode choke, a differential mode inductor and a high-performance ceramic capacitor in a compact space, which can effectively suppress electromagnetic interference in the frequency band of 10kHz-300MHz, and the suppression ability of common household appliances clutter can reach more than 40dB. Compared with the traditional socket, this product retains the functions of the five-hole/seven-hole conventional socket, and adds an independent filter module. It does not need to modify the home circuit, just plug it into the original socket like an ordinary socket, and the elderly and children can easily operate it.
The product design fully considers the diversity of home use scenarios: the shell is made of flame-retardant ABS material, which passes the glow wire test at 750℃ to ensure the safety of electricity use; Equipped with a child safety door to prevent accidental contact and electric shock; Built-in overload protection device can automatically cut off power when the total power exceeds 2500W, which is suitable for high-power appliances such as air conditioners and electric ovens. In addition, the top of the filter is equipped with LED indicator light, green indicates normal operation, and red indicates overload or failure, so that users can intuitively grasp the equipment status.
The actual home test data show that after the filter is used to connect TV, set-top box and audio in the living room, the Xue Huadian of TV picture is reduced by 90%, and the noise floor of audio is reduced to almost inaudible. Connecting the router and projector in the bedroom can improve the stability of WiFi signal by 60% and reduce the number of video jams by 75%. A user's feedback: "Before the microwave oven started, the router always disconnected the network. After plugging in this filter, it never happened again, and the operation was particularly simple."
At present, Fengchuang socket filter offers two models: five-hole basic model and seven-hole USB model. The price is close to the people, and it has passed the national 3C certification, and it has been listed simultaneously on the e-commerce platform and offline appliance stores. In the future, Fengchuang will also launch an upgraded model with intelligent monitoring function, and display the filtering effect and power consumption data in real time through the mobile APP to further enhance the home power consumption experience. The listing of this product indicates that Fengchuang will extend the professional filtering technology from the industrial field to the civil market, and solve the problem of power interference for millions of families.
