Certification Introduction

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

CEC certification meaning

As more and more electronic products appear in daily life, "saving energy" will become an urgent problem that everyone must face in the 21st century. The 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 the shock.

The 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 be used in standby and in use. Use energy in a more efficient way.

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 be changed in design.

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 California's external power supplies can comply with the new standards, California will be able to reduce more than 360,000 tons of carbon dioxide emissions each year, which is equivalent to the annual emissions of 60,000 cars.

The regulations stipulate that electrical products must first meet the equipment energy efficiency regulations when they are sold in California. The regulations stipulate energy efficiency index requirements, measurement methods and phased implementation plans for 58 types of electrical products. According to the requirements of this regulation, electrical products must be tested by qualified laboratories in accordance with the corresponding American regulations or standards, and they can be sold in California after the certification meets the requirements.

Applicable product range

The 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 be used in standby and in use. Use energy in a more efficient way. The definition scope of CEC's external power supply is: single-phase voltage input AC/DC or AC/AC external power adapter.

Application information

1. Product name: provide the full name of the product

2. Product model: list all the product models, varieties or classification numbers that need to be tested in detail

3. The intended use of the product: such as homes, offices, factories, coal mines, ships, etc.

4. Parts list: list the parts and models (classification number), ratings, and manufacturer's name that make up the product in detail. For insulating materials, please provide the name of the raw material

5. Electrical performance: For electronic and electrical products, provide point schematic diagram (circuit diagram), ingredient list, etc.

6. Structure diagram: For most products, the structure diagram or exploded diagram, ingredient list, etc. of the product shall be provided

7. Product photos, instructions for use, safety matters or installation instructions, etc.

Testing requirements

⑴ Summary: Test adjustment, unless otherwise specified, the test is carried out in accordance with the following test conditions.

⑵ Test

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

⑶ Test room according to the standard requirements of IEC 62301, the air flow in the test room must be 0.5m/s or less, the surrounding environment temperature must be controlled within the range of 23℃±5℃, and the sample must be placed on the test bench without heat conduction Test it on. For products used outdoors, if there are additional test requirements, it must be stated in the report.

⑷ The test voltage is in accordance with the standard requirements of IEC 62301, and the fluctuation range of the test voltage cannot exceed ±1% of the specified test voltage and ±1% of the specified test frequency. If the input voltage marked 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 close ones of the above two test voltages.

⑸ The result is judged that California Energy Efficiency Law stipulates that from July 1, 2006, all external power supplies exported to California must meet the average energy efficiency regulations and no-load power requirements in the following table (see Table 1)

From January 1, 2008, all external power supplies exported to California must meet the new average energy efficiency regulations and no-load power requirements in the following table TABLE2 (see Table 2)

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

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

To calculate the current energy efficiency value, and then average the energy efficiency values measured under the four load conditions of 100%, 75%, 50%, and 25% to obtain the average energy efficiency value. In addition, it is necessary to test the load when the output current is 0% The input power value, the average energy efficiency value and no-load power value obtained from the above test are determined according to the limit requirements of TABLE1 and TABLE2 to determine whether it meets which energy efficiency mark.
