How many people have been fooled by useless power savers? Is there really a power saver?

The so-called power saver, which used to save 60% electricity by the manufacturer, is made up of several capacitors in parallel. A small capacitor is also connected in parallel with the lamp holder of the live demonstration terminal board. The economizer is actually a set of capacitors. When the capacitor is discharged, the speed of the meter is slow, while when the capacitor is charged, the speed of the meter is fast. The electric light was on all the time. During the demonstration, people only saw the discharge process of the economizer, and the meter speed slowed down. In fact, the real total electricity consumption has increased, saving electricity. Today's industrial enterprises do have a lot of energy-saving space. Installing energy-saving products correctly and effectively can help enterprises save most of their operating costs, so don't look at energy-saving products with prejudice. Know a little about your situation in the energy-saving industry and you will know if you have been cheated. In this regard, Shenzhen Wanshengda generally adopts speed regulation technology or compensation technology to save power load, while for resistive load saving, it mainly adopts voltage regulation and power adjustment technology. Of course, saving electricity is not a simple speed regulation and voltage regulation. It is not easy to save electricity while fully considering the basic requirements and limiting factors of load application places and the electrical characteristics of each load itself. Generally speaking, the power saver can save electricity. Wanshengda Technology was established in 2000 and has a history of 13 years. Since the establishment of the enterprise, Wanshengda Technology has always maintained the core competitiveness of its products, independently researched and developed patented technologies, and constantly conducted technical exchanges with European and American countries to continuously enhance the competitiveness of its products among peers. Specifically embodied in: independent research and development of patented technology: Wanshengda Technology has six national patent certificates, and its products will be upgraded every one or two years, so that energy-saving frequency conversion products can better meet the market demand. High cost performance: low price attracts customers, high quality retains customers. Wanshengda Technology has established a strong cost advantage with leading technology, advanced production equipment and technology and large-scale procurement. However, Wanshengda has always insisted on not taking the initiative to fight price wars, using materials in good faith (the main components are imported from famous foreign brands), and the quality is not discounted, providing customers with cost-effective products with good consistency, high stability and strong reliability. All-round service: Wanshengda technology series energy-saving controller and inverter products, 12 months warranty, lifetime paid service. Service response time: 2 hours after the user's service request, the preliminary treatment scheme is given. Arrive at the scene within 48 hours if the fault cannot be eliminated. Wanshengda Technology solemnly promises: if it fails to reach the promised minimum power saving rate, it will be refunded unconditionally! Wanshengda invests in energy-saving transformation and shares power saving with you.
