25.5 (max) 24.7 (min)

Maximum air speed (m/s) 0.1 Test Procedure The tests are carried out in a room that has an air speed close to test sample of ＜ 0.5m/s, and the ambient temperature is maintained at 23±5℃. 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.
