The EMC standard for switch mode power supplies is a specification requirement for their electromagnetic compatibility performance, to ensure stable operation in interference environments without generating electromagnetic radiation that hinders the normal operation of other electrical equipment. Switching power supplies need to meet relevant standards such as EN55022, CISPR 22, and FCC PART15B during production.
2. Safety standard requirements
The safety standards for switch mode power supplies usually require that there should be no issues such as leakage or electric shock during use, and there should be no safety hazards such as overheating or fire. The safety standards of switch mode power supplies usually require compliance with relevant national and regional safety certification standards such as IEC60950-1 and GB4943.
3. Energy efficiency standard requirements
In order to ensure that switching power supplies can achieve the best energy efficiency level during use, countries have formulated relevant energy efficiency standards to promote energy conservation and emission reduction of switching power supplies. At present, EU ERP, US DoE, China Energy Efficiency Labeling, etc. all include energy efficiency requirements specifications for switch mode power supplies.
4. Other standard requirements
In addition, the switching power supply also needs to meet some special standard requirements, such as waterproof, dustproof, high-altitude and other special environmental standards, to ensure the reliability and stability of the switching power supply. Meanwhile, switch mode power supplies in different application fields also need to meet corresponding industry standards and certification requirements.
In summary, there are many types of standards that switching power supplies require to meet. Different manufacturers need to select corresponding standards based on their own production and sales needs to ensure the safety, reliability, and energy efficiency of their products during production.
