The test voltages are 230Vac at 50Hz. And 115Vac at 60Hz The test sample was operated at 100% of nameplate current output for at least 30 minutes immediately prior to conducting efficiency measurements. After this warm-up period, if the power level does not drift by more than 5% from the maximum value observed, the EUT can be considered stable and then the measurements were recorded at the end of the 5 minutes period. Subsequent load conditi ons can then be measured under the same 5 minutes stability. Page 3 of 12

8 Summary of test results According to the ecodesign requirements stated in Annex I, the limits of the no-load condition power consumption and the average active efficiency of the Unit Under Test (UUT) are varied based on its nameplate output power (P o). The limits are defined at two stages, the verdict of this test report is assessed based on the limit of the second stage. The no-load condition power consumption shall not exceed the following limits: AC-AC external power supplies, except low AC-DC external power supplies, except low Low voltage external power supplies / voltage external power supplies voltage external power supplies Po 51.0 W 0.5 W 0.3 W 0.3W Po > 51.0 W 0.5 W 0.5 W The no-load condition power consumption shall not exceed 0.50W 0.05 W pass The average active efficiency shall be not less than the following limits: / AC-AC and AC-DC external power supplies, except low voltage Low voltage external power supplies external power supplies Po 1.0W * Po * Po W<Po 51.0 W * ln (Po) * ln (Po) Po > 51.0 W The test results comply with the second stage requirement s of (EC) No.278/2009 Page 8 of 12
