AC-DC power adapter latest efficiency VI standard

AC-DC power adapter latest efficiency VI standard
Efficiency VI standards are mainly aimed at external power products. With the increasing awareness of energy saving and environmental protection, increasingly higher requirements for external power supplies (such as current adapters, switching power supplies, chargers, etc.), that more and more AC-DC power adapter manufacturers will officially launch efficiency VI since 2016. The efficiency of the external AC-DC power supply in the active mode has higher no-load power consumption requirements than the current requirements. That's why the power meter requirements for power measurement are also higher than before. According to the current US and European standards, the accuracy of the power meter should not less than 0.15%.
