⑴ Summary: Test adjustment, unless otherwise specified, is carried out in accordance with the following test conditions.

⑵ Test

Instrument: Power measurements must be tested with a calibrated voltammeter or power analyzer. The instrument must be calibrated according to the IEC 62301 standard, and the error must be less than or equal to 2% when the test power is 0.5W. When the test power is less than 0.5W, the error must be less than 0.01W. The accuracy of the power test instrument must reach 0.01W or better. The error of the test voltage and current must be less than or equal to 2%.

⑶ Test room According to the IEC 62301 standard requirements, the air flow in the test room must be 0.5m/s or less, the ambient temperature must be controlled within the range of 23℃±5℃, and the sample must be placed on a test bench without heat conduction for testing. If there are additional test requirements for products used outdoors, they must be stated in the report.

⑷ Test voltage According to the standard requirements of IEC 62301, the fluctuation range of the test voltage cannot exceed ±1% of the specified test voltage and ±1% of the specified test frequency. If the input voltage on the nameplate is wide voltage, the test voltage is 115V/60Hz and 230V/50Hz. If the nameplate indicates a single voltage input, the test voltage is one of the two test voltages that are close to each other.

⑸ Result judgment The California Energy Efficiency Act stipulates that from July 1, 2006, all external power supplies exported to California, the United States must meet the average energy efficiency regulations and no-load power requirements in the following table (see Table 1)

And from January 1, 2008, all external power supplies exported to California, the United States must meet the new average energy efficiency regulations and no-load power requirements in the following table TABLE2 (see Table 2)

All tests must take into account the load conditions of 100%, 75%, 50%, and 25% of the output current indicated on the nameplate (Note: the error range of the load here cannot exceed ±2%), respectively Record its input power, input current, power factor, output voltage, and THD (total harmonic distortion), and then calculate the current energy efficiency value according to

Energy efficiency = (output voltage × output current) / input power

, and then average the energy efficiency values measured under four load conditions of 100%, 75%, 50%, and 25% to obtain the average energy efficiency value. In addition, the input power value when the output current is 0% load must also be tested. The average energy efficiency value and no-load power value obtained from the above tests are judged according to the limit requirements of TABLE1 and TABLE2 to determine whether they meet which energy efficiency mark.
