Switching DC power supply and the linear power supply different class of stable power supply is switched-mode DC power supply, Linyi LED display its circuit pattern mainly single-ended flyback, single-ended forward, half-bridge, push-pull and full-bridge. The fundamental difference between it and the LED display Linyi linear power transformer is that it does not work in the frequency but in tens of kHz to several MHz. Shandong LED Display Function tube is not working in the saturation region, that is the cut-off switch state; switching power supply, hence the name Shandong full color. Advantages Linyi LED display manufacturers switching power supply small size full-color cost, light weight, stable and reliable; Linyi LED disadvantage relative to the linear power supply ripple is large (typically ≤1% VO (PP), good can be achieved dozen mV (PP) or less). Linyi can display its power from a few watts - are the product of several kilowatts. The price of 3 yuan - more than ten million price / watt color screen, here are a few on the general habit of switching power supply category: Linyi Wang Tai Electronics Co., Ltd. is a company specializing in the design, development, production and sales of LED displays, LED advertising cards, LED entertainment applications, LED color LED products and other products of high-tech enterprises, is the field of LED optoelectronic integrated operator service company since its inception fully focused on the development of full-color LED display, production, sales and engineering installation services, is committed to providing customers with comprehensive information systems solutions for publishing.
