When it comes to power supplies, there are several certifications that are commonly used to ensure their safety and performance standards. Here are some of the most widely recognized certifications for power supplies:
80 PLUS: This certification is focused on energy efficiency and is commonly used for computer power supplies. The 80 PLUS certification program has different levels such as 80 PLUS, 80 PLUS Bronze, 80 PLUS Silver, 80 PLUS Gold, 80 PLUS Platinum, and 80 PLUS Titanium, each indicating a higher level of energy efficiency.
UL (Underwriters Laboratories) Certification: UL is a global safety science company that provides various certifications for electrical products. UL certification ensures that the power supply meets specific safety standards and has undergone rigorous testing.
CE (Conformité Européene) Marking: CE marking is a mandatory conformity mark for products sold within the European Economic Area (EEA). It indicates that the power supply complies with European safety, health, and environmental protection requirements.
FCC (Federal Communications Commission) Certification: The FCC certification is required for power supplies that emit radio frequency energy. It ensures that the power supply meets electromagnetic interference (EMI) standards and won't interfere with other electronic devices.
RoHS (Restriction of Hazardous Substances) Compliance: RoHS is a directive that restricts the use of certain hazardous substances in electrical and electronic equipment, including power supplies. RoHS compliance indicates that the power supply is free from substances such as lead, mercury, cadmium, and other harmful materials.
It's important to note that the specific certifications required may vary depending on the region, application, and intended use of the power supply. Manufacturers typically display the relevant certification logos or mention them in the product specifications and documentation. When purchasing a power supply, it's recommended to look for these certifications to ensure its safety and compliance with industry standards.
