⑴ Summary: Test adjustment, unless otherwise specified, the test is carried out in accordance with the following test conditions.
⑵ Test Instrument: The power measurement must be tested with a calibrated voltammeter or power analyzer. The instrument must be calibrated according to the IEC 62301 standard. When the test power is 0.5W, the error must be less than or equal to 2%. 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 tested voltage and current must be less than or equal to 2%.
⑶ Test room according to the standard requirements of IEC 62301, the air flow in the test room must be 0.5m/s or less, the surrounding environment temperature must be controlled within the range of 23℃±5℃, and the sample must be placed on the test bench without heat conduction Test it on. For products used outdoors, if there are additional test requirements, it must be stated in the report. ⑷ The test voltage is in accordance with the standard requirements of IEC 62301, and 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 marked on the nameplate is a 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 close ones of the above two test voltages. ⑸ The result is judged that California Energy Efficiency Law stipulates that from July 1, 2006, all external power supplies exported to California must meet the average energy efficiency regulations and no-load power requirements in the following table (see Table 1) From January 1, 2008, all external power supplies exported to California 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%, 25% of the output current indicated on the nameplate (note: the error range of the load here cannot exceed ±2%), and record the input power respectively. Input current, power factor, output voltage, and THD (total harmonic distortion), and then follow Energy efficiency = (output voltage × output current)/input power
To calculate the current energy efficiency value, and then average the energy efficiency values measured under the four load conditions of 100%, 75%, 50%, and 25% to obtain the average energy efficiency value. In addition, it is necessary to test the load when the output current is 0% The input power value, the average energy efficiency value and no-load power value obtained from the above test are determined according to the limit requirements of TABLE1 and TABLE2 to determine whether it meets which energy efficiency mark.
