AC power supply capable of providing a stable voltage and frequency of the AC power supply, said stable power supply. Shandong full color work done by the majority of domestic manufacturers of AC voltage stability. The following AC power supply with market some brief classification features. Parameter adjustment (resonance) type such power supply, the basic principles of Shandong LED display regulator is LC series resonant, full color manufacturers offer early stage of magnetic saturation regulator fall into this category. Shandong full color display manufacturers it has the advantage of simple structure, without many of the components of Linyi color screen, full-color reliability is quite high voltage range is quite wide, full-color manufacturers interference and strong anti-overload. The disadvantage is that energy consumption, noise Big, bulky and high cost. Shandong Power LED display Compensation Type - regulator purifier (including precision regulator) which links with the compensation achieve a stable output voltage, Linyi LED display is easy to realize computer control. Its advantage is a good LED display, high voltage accuracy (≤ ± 1%) anti-jamming performance, fast response (40 ~ 60ms), the circuit is simple, reliable work. Disadvantages are: low-frequency oscillation phenomena with computers, Shandong full color PBX nonlinear loads; input-side current distortion large color screen in Shandong, the source power factor is low; Linyi LED display offer an output voltage on the input voltage phase shift . LED display higher requirements for anti-interference function units, Shandong LED display manufacturers offer application is appropriate in the city, when the computer is powered, Linyi LED display must use the computer for about 2-3 times the total power regulator to use. Due to a regulation, interference, fast response, affordable, and other advantages, it is widely used. p10-color screen, color screen Jining, Tai Wang photoelectric provided by Linyi Wang Tai Electronics Co., Linyi Wang Tai Electronics Co., Ltd. (www.ledzkd.com) (www.ledzkd.com) strong, credible, in Linyi display equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Hong Thai Optical into the brilliant and you work for a better future!
