GB 20943-2013 Minimum allowable values of energy efficiency and evaluating values of energy conservation for single voltage external AC-DC and AC-AC power supplies (English Version)
1 Scope
This standard specifies the minimum allowable values of energy efficiency, evaluating values of energy conservation, test method and inspection rules for external power supply (hereinafter referred to as product) which converts the AC voltage to fixed single low pressure DC (not greater than 36V) or low pressure AC (not greater than 36V) output voltage under the conditions of 220V and 50Hz power supply.
This standard is applicable to the product with rated output power not larger than 250W.
This standard is not applicable to DC-DC power supply and products for special purpose such as powering industrial equipment, medical device and etc.
