Code of Conduct for EPS Version 4 (March 2009)
The aim of the Code of Conduct on Energy Efficiency of External Power Supplies is to minimize energy consumption of external power supplies both under no-load and load
conditions in the output power range 0.3W to 250W. The scope of the Code of Conduct are single voltage external ac-dc and ac-ac power supplies for electronic and electrical appliances, including among
others AC adapters, battery chargers for mobile phones, domestic appliances, power tools and IT equipment, in the output power range 0.3W to 250W.
The signatories of the Code of Conduct shall achieve both the no-load power consumption and on-mode efficiency targets shown in Table 1.1, 1.2 and Table 2.1 and 2.2.
