Current Crest factor (CF)

發(fā)布時(shí)間: 2010/04/07 人氣 :2250
·Current Crest factor (CF)
Current crest factor is the ratio of electric current periodic waveforms' peak value and effective value. When the computer load accept sine wave voltage, its absorption energy is not always according to the sine rule, and will cause a higher peak current (range from 2.4-2.6 times). Therefore, UPS should be designed to provide the current that CF value is greater than 3, to satisfy the application of computer load.
