Analysis of LED drive power through CE certification requirements

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 to two broad categories of content requirements: EMC (electromagnetic interference) and FCC (safety regulations). Different countries, different certification standards specific requirements of different parameters have nothing more.
First, EMC, EMS and EMI, including two parts, in general, EMS includes four aspects: lightning test, EFD (quick burst test), EST (static testing) and C / S (Anti-conduction testing); EMI includes three aspects: transmission test, magnetic radiation, space radiation, each content standard test parameters are detailed requirements of the content in many of these have their own certification which the certification number, and that standards are hierarchical For example, do you get your product CE certification, in the EMS for each item no more than 4 full load test results: 1 Product broken --- F (failure); testing process crash, reboot to resume normal work - -C level achieved; testing of products subject to interference, the output load has fluctuated --- B-class standards; testing process, there is no change in output --- A-level standards for the best.
Second, the Certification, the so-called safety is the safety requirements, to the safety requirements of each certification standards for certification by the standard, which is divided into six key areas: 1. Temperature: including the shell, X capacitors, coils ( inductors and transformers), optical coupling, transformer skeleton, power cord, PCB board; 2. Pressure: between input and output: a basic and functional insulation voltage insulation requirements (reinforced insulation requirements) of the specific voltage requirements; 3. leakage Current: The output power is not the same in different specific requirements; 4. input and output parameters required; 5. mechanical requirements: including the distance between the input line, the distance between two points fuses, transformer primary, secondary, etc. ; 6. the overall structure of products, different products have different specific requirements.
In general, we should have certified the case, from the above two items, and these two items to do the specific content requirements of each, and only to the requirements of these projects, only to achieve the overall requirements of each standard in order to successfully export your products to Europe and the United States.
Abou testing and certification laboratory, is specialized in lighting, power supply, LED driver power supply testing and certification of exports, CE certification, FCC certification, South Korea KC certification, UL certification and so on. And long-term with many large-scale lighting, power enterprises, such as the JW-source technology, Swiss Valley Technology, HKC (Kyushu sun), the nuclear of COSCO pass, NIVS Group on Optoelectronics, SED International.
AMB is now build 9 * 6 * 6 chamber, in accordance with international standards, dark room with absorbing material, is the standard EMC laboratory. EMC launched a test in two hours free, UL, KC, CCC, GS certified product evaluation free of charge before
