The six level energy efficiency standard is mainly for external power products. With the enhancement of people's awareness of energy conservation and environmental protection, AC-DC power adapter manufacturers have higher and higher requirements for external power supplies (such as current adapters, switching power supplies, chargers, etc.), and will officially launch the six level energy efficiency standard in 2016. The no-load power consumption requirements for the efficiency of external AC-DC power supplies in active mode are higher than the current requirements, so the requirements for power meters for power measurement are higher, According to the current standards of the United States and Europe, the accuracy of the power meter shall not be less than 0.15%. Requirements of COC V5 for power consumption of six level energy efficiency AC DC power adapter in no-load mode efficiency requirements of COC V5 for AC DC power adapter (excluding low-voltage external power supply) efficiency requirements of COC V5 for AC DC power adapter (low-voltage external power supply)
Energy efficiency grade of six grade AC-DC power adapter
Energy efficiency grade: it is a grading method that indicates the difference between the energy efficiency of household appliances. According to the relevant provisions of the standard,
Grade 1 indicates that the product has reached the level of power saving and low energy consumption;
Grade 2 indicates that the product is relatively energy-saving;
Grade 3 indicates that the energy efficiency of products is the average level of China's market;
Grade 4 indicates that the energy efficiency of the product is lower than the market average level;
Grade 5 is the market access index of products. Products lower than the requirements of this grade are not allowed to be produced and sold.
Hierarchical definition
The energy efficiency index of Grade A + is 30% ~ 42%, that is, the measured power consumption under standard conditions is equivalent to 30% ~ 42% of the rated power consumption. The energy efficiency grades of air conditioners and refrigerators marked with energy efficiency grades are divided into five grades.
At present, more than 100 countries have implemented the energy efficiency labeling system. It is a color logo with blue and white background, which is divided into 5 levels: 1, 2, 3, 4 and 5,
Grade 1 indicates that the product reaches the standard and saves electricity, that is, the energy consumption is low;
Level 2 indicates relatively power saving;
Grade 3 indicates that the energy efficiency of the product is the average level of China's market;
Grade 4 indicates that the energy efficiency of the product is lower than the market average level;
Grade 5 is the market access index. Products lower than the requirements of this grade are not allowed to be produced and sold. The energy efficiency label is a color label with sticky back and the words "China energy label" on the top, which is generally pasted on the front panel of the product.
