Linear stabilized linear power supply stable power supply have a common Shandong full color feature is its power adjustment device operating in the linear region, Linyi LED display by adjusting the voltage drop between the tube to stabilize the output. Shandong LED display large losses due to the adjustment of the static tube, LED display need to install a large radiator to heat it. And because the transformer in the frequency Shandong full color manufacturers offer (50Hz) display, so the larger weight. Advantages of such power and high stability full color manufacturers, small ripple outdoor led display, high reliability, easy to make multiple bus led display, continuously adjustable output products. The disadvantage is bulky, relatively heavy, relatively low efficiency. Such stable power supply there are many led display manufacturers, full color output prices from nature can be divided power supply and constant current power supply and set regulators, Shandong Full Color prices on a steady flow of steady flow (bistable ) power supply. The output value from the point of view can be divided into fixed output power, the band switch and potentiometer adjustment type continuously adjustable several. Linyi LED display indicates the divided output from the pointer type and a digital display type, and so on. ESD damaged devices to show dim, fuzzy, off, short or low VF or VR. ESD damaged devices should not be confused with electronic overload, such as: design or because of an error in the current drive, wafer mount, wire shield grounding or packaging, or general environment induced stress. ESD security and control procedures: most electronic and electro-optical company ESD is very similar and has successfully achieved so ESD control equipment, manipulation, and the main program. These procedures have been used since ancient ESD testing the quality of the effect of the instrument. ISO-9000 certification also put him out as normal control procedures. Indoor led display, Yasuhiro photovoltaic (certification), the display is provided by Linyi Qingdao Hong Electronics Co., Ltd. Thailand. 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.
