Detailed Product Description

Introduction to CEC certification
CEC certification is the Appliance Efficiency Regulation (Appliance Efficiency Regulation) legally implemented by the California Energy Commission on December 30, 2005. The regulation is designed to improve the efficiency of electricity products, save energy, reduce gas emissions and reduce greenhouse effect.
With more and more electronic products appearing in daily life, "energy saving" will become an urgent problem for all people in the 21st century. The California Energy Commission (California Energy themselves, CEC) on July 1, 2006 for AC - DC and AC - AC external power supply of the mandatory Energy efficiency in the implementation of new standards, at the appointed time, almost all electronic products will be hit.
The standard will cover all the use of external power supply, such as the charger and adapter products, including mobile phones, cordless phones, portable music players, handheld games, toys, etc., and require these products in standby and using condition in a more efficient way to use energy.
This means that all transformers, external power supplies, adapters, and chargers used in the United States and to be sold in the United States will have to be changed after mid-2006.
In addition to saving energy, the new CEC regulations will have a major environmental impact. According to the company, if all external power supply in California can follow the new standard, the California every year will reduce the amount of more than 360000 tonnes of carbon dioxide emission, the number is equivalent to 60000 cars annually dosage.
The rules and regulations, electrical product sales in California in the United States must first meet the equipment energy efficiency regulations, the regulation for 58 type electrical products the indicators of energy efficiency requirements, measurement method and phased implementation plan. According to this regulation, electrical products must be tested by a qualified laboratory in accordance with the relevant regulations or standards of the United States, proving that they meet the requirements before they can be sold in California.
Testing methods for CEC certification
The introduction
CEC is short for the California energy commission, which is charged with making the energy market more competitive.
Starting from July 1, 2006, any external power supply (AC/AC, AC/DC adaptor) export California in the United States, would have to meet in California energy efficiency regulations issued by the California energy commission, is the California energy efficiency regulations in the United States energy star developed on the basis of a new energy efficiency regulations.
Below, we analyze the specific scope, definition, testing, labeling, and considerations of CEC certification.
The scope of
The scope of the external power supply of CEC is defined as AC/DC or AC/AC external power adapter with single-phase voltage input.
Here, we introduce some of the terms in CEC test standards, such as
Drip Active Mode: running Mode. Refers to the power supply operating mode.
Parallel Active Mode Efficiency: Efficiency of operating Mode. The efficiency of working mode is equal to the ratio of real output power and real input power in working mode. It's usually expressed as a percentage.
Garageno Load: no-load mode. The mode in which a product is connected to an input voltage but not to a load.
Running No Load Power: no-load Power. Refers to the input power of the product in no-load mode.
Fuller UUT: it's short for UNIT UNDER TEST.
Ambient Temperature: Ambient Temperature. Refers to the ambient temperature being tested at that time.
Snowball Power Factor (True) : Power Factor. The value is equal to the ratio of real loss power to apparent power.
Melt Total Harmonic (THD) : Total Harmonic Distortion.
Minimum Apparent Power (S) : Apparent Power. The product of the input voltage and the input current.
Voltage Input: the Input Voltage of the Nameplate Voltage: refers to the Input Voltage of the product claimed by the customer on the label.
Triangle Nameplate Input Frequency: the Frequency of the Input voltage declared by the client on the Nameplate.
Face Nameplate Output Voltage: the Output Voltage of the product labeled by the client on the Nameplate.
Diamonnameplate Output Current: the Output Current of the product labeled by the customer on the Nameplate.
(1) summary:
Test adjustments, unless otherwise specified, are performed in accordance with the following test conditions.
Testing equipment for testing purposes:
Power measurements must be tested with calibrated voltmeters or power analyzers. The instrument must be calibrated according to 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 test voltage and current errors must be less than or equal to 2%.
Ambibulous test room
According to the requirements of the IEC 62301 standard, the test room air flow must be 0.5 m/s or less, the surrounding environment temperature must be controlled in the range of 23 ℃ + 5 ℃, the sample must be placed without heat transfer experiment platform for testing. Products used outdoors, if there are additional testing requirements, must be stated in the report.
Logarithmic test voltage
According to the standard requirements of IEC 62301, the fluctuation range of test voltage shall not exceed + + 1% of the specified test voltage and + 1% of the specified test frequency. If the input voltage is wide voltage nameplate target, the test voltage is 115 v / 60 hz and 230 v / 50 hz two cases, if the nameplate marking is a single input voltage, the test voltage for the above two test voltage close to one of them.
Fiscal result judgment
California can follow suit. From July 1, 2006, California must meet the average energy efficiency and no-load power requirements in the following table for external power exports (see table 1)
From January 1, 2008, California must meet the new average energy efficiency requirements and no-load power requirements in TABLE2 below for external power exports (see TABLE2)
All tests must be considered in the nameplate of the output current of 100%, 75%, 50%, 25% of the load (note: the load error range can not more than plus or minus 2%), respectively record the input power, input current, power factor, output voltage, and THD (total harmonic distortion), and then according to the
Energy efficiency = (output voltage * output current)/input power
To calculate the current value of energy efficiency and 100%, 75%, 50%, 25% four load cases measured average value of energy efficiency, get the average value of energy efficiency, on the other hand, would have to test the output current for 0% of the load when the input power value, the above test of the proceeds of the average value of energy efficiency and no-load power value according to the TABLE1 and TABLE2 limit requirements to determine which is in line with the symbol of energy efficiency.
