CEC certification As more and more electronic products appear in daily life, "saving energy" will become an urgent problem that everyone in the 21st century must face. The California Energy Commission (California Energy Commission, CEC) will implement a new mandatory standard for the energy efficiency of AC-DC and AC-AC external power supplies on July 1, 2006. By then, almost all electronic products will suffer Impact. This means that after mid-2006, all transformers, external power supplies, adapters, and chargers used in the United States and sold to the United States must change their design. In addition to saving energy, the new CEC specifications will also be in Environmental protection has a major impact. According to the company’s statistics, if all California’s external power supplies can comply with the new standards, California will be able to reduce carbon dioxide emissions by more than 360,000 tons per year, which is equivalent to the annual emissions of 60,000 vehicles. The regulation stipulates that electrical products must first meet the equipment energy efficiency regulations when they are sold in California, the United States, which stipulates energy efficiency index requirements, measurement methods and plans for phased implementation for 58 types of electrical products. Qualified laboratories will conduct testing according to the corresponding US regulations or standards and prove that they meet the requirements before they can be sold in California, USA.
