Test Results

The measurements of the device produced satisfying values, which were all within the specifications:

Input: 358 watts (214 volts, 2.33 amperes, cosphi 0.77)
Output: 300 watts (18.2 amperes/3.3 volts, 12 amperes/5 volts and two times 7.5 amperes at 12 volts)
Electrical efficiency under maximum load: 83.5 percent (59 watts of dissipation warms the air by just under 27°F (15 °C))
Noise measurement under maximum load: none, since no ventilator


原來測試環境是Voltage 214 V Current 2.33 A COS=0.77 Pi=384w Po=300w
(原文的輸入功率我不知道是它算錯還是我算錯.......214*2.33*0.77...


input 214 V Current 2.33 cos =0.77
pi=214*2.33*0.77=383.9 W~~~~~這是輸入的實功
Po=380 W ~~~~~~~~~~~~~~~這是輸出的實功
EFF= 300/384 =78.12%
