At present, high-power luminaire products on the market have corresponding certification requirements. Among them, high PF and low THD are important indicators. Linear application products must be opened in multiple stages in each mains cycle to achieve high PF and low THD. In the application of high-power solutions, multiple ICs need to be used in parallel. In this case, it is inevitable to generate more jumper resistance at the parallel port, which will result in lowering the spacing of the traces, reliability, etc., and PCB layout is difficult. The overall layout is not beautiful, and the peripheral cost is high. To this end, our SM2325E innovative products came into being, eliminating the need for external jumper resistance, reducing external interference, improving system application reliability, and saving peripheral application costs. 50W typical application program performance parameters: Graded harmonic test data: EMI test items: The SM2325E solution supports: PF is greater than 0.9 THD is less than 10%, meeting the requirements of fractional harmonics IEC61000-3-2 (Class C) Can pass EMI and other certification standards Mingwei Electronics aims: the sun and the moon, the perfection Mingwei Electronics Core Values: Integrity, Integrity Mingwei electronic technology route: quality, cost, refinement, and win-win
The latest Windows has multiple versions, including Basic, Home, and Ultimate. Windows has developed from a simple GUI to a typical operating system with its own file format and drivers, and has actually become the most user-friendly operating system. Windows has added the Multiple Desktops feature. This function allows users to use multiple desktop environments under the same operating system, that is, users can switch between different desktop environments according to their needs. It can be said that on the tablet platform, the Windows operating system has a good foundation.
