GB 20943-2025 Minimum Allowable Values of Energy Efficiency and Energy Efficiency Grades for AC-DC and AC-AC Power Supplies

Policy Details

交流-直流和交流-交流电源能效限定值及能效等级
Source
This revised policy substantially expands its regulatory scope through the inclusion of additional product categories and extended power capacity ranges, while integrating embedded power supplies into its framework for the first time. Aligned with the European Union’s latest minimum energy efficiency requirements of power supplies, GB 20943-2025 introduces a globally pioneering specification for Grade 1 no-load power consumption, establishing a stringent threshold of 0.05W to 0.075W.

It will replace the existing standard (GB 20943-2013). AC is alternating current (AC) and DC is direct current (DC).
