CEC certification is the Appliance Efficiency Regulation implemented by the California Energy Commission on December 30, 2005, in accordance with the law. The purpose of implementing this regulation is to improve the efficiency of electrical products, save energy, reduce gas emissions and greenhouse effect.

The significance of CEC certification

With more and more electronic products appearing in daily life, "saving energy" will become an urgent issue that everyone must face in the 21st century. The California Energy Commission (CEC) is about to implement new mandatory standards for energy efficiency of AC-DC and AC-AC external power supplies on July 1, 2006, which will impact almost all electronic products.

This standard will cover all products that use external power supplies (such as chargers and adapters), including mobile phones, home wireless phones, portable music players, handheld game consoles, toys, etc., and require these products to use energy more efficiently in standby and use states.

This means that after mid-2006, all transformers, external power supplies, adapters, and chargers used and intended for sale in the United States must undergo design changes.

In addition to saving energy, CEC's new regulations will also have a significant impact on environmental protection. According to the company's statistics, if all external power supplies in California could comply with the new standards, California would be able to reduce over 360000 tons of carbon dioxide emissions annually, which is equivalent to the annual emissions of 60000 cars.

This regulation stipulates that electrical products sold in California, USA must first comply with equipment energy efficiency regulations. The regulation specifies energy efficiency index requirements, measurement methods, and phased implementation plans for 58 types of electrical products. According to the regulations, electrical products must be tested by qualified laboratories in accordance with relevant US regulations or standards to prove compliance before they can be sold in California, USA.

Applicable product scope

This standard will cover all products that use external power supplies (such as chargers and adapters), including mobile phones, home wireless phones, portable music players, handheld game consoles, toys, etc., and require these products to use energy more efficiently in standby and use states. The scope of CEC's external power supply definition is: AC/DC or AC/AC external power adapters with single-phase voltage input.

Application materials

1. Product Name: Provide the full name of the product

2. Product model: List in detail all product models, varieties, or classification numbers that require experimentation

3. Intended use of the product: such as home, office, factory, coal mine, ship, etc

4. Parts list: Detailed list of the components and models (classification numbers) that make up the product, rated values, and manufacturer names. For insulation materials, please provide the names of the raw materials

5. Electrical performance: For electronic and electrical products, provide schematic diagrams (circuit diagrams), ingredient lists, etc

6. Structure diagram: For most products, it is necessary to provide the product's structure diagram or explosion diagram, ingredient list, etc

7. Product photos, usage instructions, safety precautions, or installation instructions, etc

Test requirements

⑴ Overview: Testing and adjustment are conducted according to the following testing conditions unless otherwise specified.

⑵ Testing

Instrument: Power measurement must be tested using a calibrated voltmeter or power analyzer. The instrument must be calibrated according to the IEC 62301 standard, and the error must be less than or equal to 2% when the test power is 0.5W. When testing power less than 0.5W, the error must be less than 0.01W. The accuracy of the power testing instrument must reach 0.01W or better. The error of the tested voltage and current must be less than or equal to 2%.

According to the standard requirements of IEC 62301, the air flow in the testing room must be 0.5m/s or less, the ambient temperature must be controlled within the range of 23 ℃± 5 ℃, and the sample must be tested on a test bench without thermal conduction. If there are additional testing requirements for products used outdoors, they must be stated in the report.

According to the standard requirements of IEC 62301, the fluctuation range of the test voltage should not exceed ± 1% of the specified test voltage and ± 1% of the specified test frequency. If the input voltage indicated on the nameplate is a wide voltage, the test voltage is 115V/60Hz and 230V/50Hz. If the nameplate indicates a single voltage input, the test voltage is one of the two test voltages that is close to each other.

From July 1, 2006, the California Energy Efficiency Law stipulates that all external power sources exported to California, USA must meet the average energy efficiency regulations and no-load power requirements in the following table (see Table 1)

Starting from January 1, 2008, all external power supplies exported to California, USA must meet the new average energy efficiency regulations and no-load power requirements in Table 2

All tests must take into account the load conditions of 100%, 75%, 50%, and 25% of the output current indicated on the nameplate (note: the error range of the load here cannot exceed ± 2%), record their input power, input current, power factor, output voltage, and THD (total harmonic distortion) separately, and then follow the instructions

Energy efficiency=(output voltage x output current)/input power

To calculate the current energy efficiency value, the energy efficiency values measured under four load conditions of 100%, 75%, 50%, and 25% are averaged to obtain the average energy efficiency value. In addition, the input power value of the load with an output current of 0% must be tested. The average energy efficiency value and no-load power value obtained from the above tests are judged according to the limit requirements of Table 1 and Table 2 to determine which energy efficiency label it meets.
