Analysis on LED drive power through CE certification requirements

Be resolved Tags:0 - There from the end of the problem

Europe and developed countries have strict requirements of electronic products, for export to their country of LED products are no exception, then, to be exported to their country over which standard to do, and what these standards specify the parameters important to ask for it? These two issues have been puzzled many of us.







In the electronics inside, there are many certification standards around the world, which is the big influence of UL, CE, TUV, China's 3C certification, which many standards, the content is nothing more than the two major categories of content requirements: EMC (electromagnetic interference) and FCC (safety standard). Different countries have different certification standards specify the parameters required nothing more.


First, EMC, EMS and EMI, including two parts, in general, EMS covers four areas: lightning test, EFD (quick burst test), EST (static test) and C / S (anti-conduction test); EMI mainly includes three aspects: conduction testing, magnetic fields, space radiation, each content standard test parameters are detailed requirements of these certification in a number of which has its own certification number, and that compliance is graded , for example, do you get your product CE certification in EMS full-load testing of each project is nothing more than four kinds of results: 1 Product broken --- F (fail); testing process crashes, reboots to work properly - -C-level compliance; testing products subject to interference, output load fluctuations --- B-class standards; testing process does not change the output --- A-level standard for the best.


Secondly, safety certification, safety is the so-called safety requirements, meet the safety requirements of each certification standards can be certified by the standard, which is largely divided into six items: 1. Temperature: including Shell, X capacitors, coils ( inductors and transformers), optical coupling, transformer frame, power cord, PCB board, etc.; 2 pressure: between input and output: a basic and functional insulation voltage insulation requirements (reinforced insulation requirements) of the specific voltage requirements; 3 leak Current: different output power are not the same as the specific requirements; 4 input and output parameters required; 5 mechanical requirements: including the distance between the input line, the distance between two points fuse, the transformer primary, secondary, etc. ; 6 overall structure of the product, different products have different specific requirements.


In general, to lead a certification, then from the above two items, and these two items for each specific content requirements do, only to meet these requirements of the project, only to achieve the overall requirements of each standard in order to successfully export your product to Europe countries.
