Introduction to six level energy efficiency of power adapter

2020-04-28

The six level energy efficiency standard is mainly for the external Power Supply products. With the enhancement of people's awareness of energy conservation and environmental protection, the AC-DC Power Adapter manufacturers have higher and higher requirements for the external power supply (such as current Adapter, Switching Power Supply, charger, etc.). In 2016, the six level energy efficiency standard was officially launched. The no-load power consumption requirements for the efficiency of the external AC-DC power supply in the active mode are higher than the current requirements Higher, so the power meter requirements for power measurement are higher. According to the current standards of the United States and Europe, the accuracy of the power meter is not less than 0.15%.

Level 6 energy efficiency AC-DC power adapter energy efficiency level:

Energy efficiency grade: it is a grading method to show the difference of energy efficiency of household electrical appliances, according to the relevant provisions of the standard,

Level 1 indicates that the product has reached the level of power saving and low energy consumption;

Level 2 indicates that the product is relatively energy-saving;

Level 3 indicates that the product energy efficiency is the average level of China's market;

Level 4 indicates that the energy efficiency of the product is lower than the market average;

Level 5 is the market access index of products. Products below the level are not allowed to be produced and sold.
