Switching AC power supply which applies high-frequency pulse width modulation, the difference Linyi LED display and general switching power supply is its output to the input side must be above the frequency, the same phase of the AC voltage. Shandong LED display its output voltage waveform has a quasi-square wave, trapezoid wave, sine wave, uninterruptible power supply (UPS) on the market in Shandong Shandong full color full color manufacturers offer deprived of one of the storage supply and charger, is a switching regulator AC power supply, good control, easy to implement intelligent, Linyi LED display is very promising AC power supply. However, because the circuit complexity LED display, high prices, so the promotion is slow. Sources static impact on the circuit's main source of human Shandong static full-color, plastic products and related equipment and instruments Full Color prices, from the use of the environment in which static power supply has the following items: objects, materials, flooring, furniture work overalls, packaging containers of paint or wax surfaces, organic and fiberglass materials. Cement floors, paint or waxed floor full color, plastic floor tiles or vinyl flooring. Chemical fiber clothes, non-conductive work shoes, clean cotton overalls. Plastics, packaging, boxes, bags, trays, foam liner. LED display, Yasuhiro photovoltaic (certified), Lianyungang Linyi full color provided by the Thai-Hong Electronics Co., Linyi Wang Tai Electronics Co., Ltd. (www.ledzkd.com) (www.ledzkd.com) is a leader in Linyi, a display device, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customers needs. In Hong Thai Optical leadership with the staff warmly welcome all inquiries negotiations to create the Thai macro photoelectric a better future.
