< p> new KEBO UPS power supply for the first time using demand charge first? < / p> < p> new UPS power supply for the first time using demand charge? This is a lot of buyers have doubts. In general, just bought back UPS power are not satisfied, then let's demand for electricity talented enough for normal use, but after a period of time and need discharge time, in order to maintain the charging function of power from being damaged. Discharge time interval of about three months and half cargo discharge will be better. Need to remember is that for the first time after put the electricity must charge more than 12 hours, such ability prolong stature of UPS power supply, UPS power supply for the operation of these illustrate the book there are, of course. < / p> < p> KEBOUPS power inverter is mainly composed of filter circuit, control logic and the inverter bridge three parts. < / p> < p> inverter is used for the direct current (dc) of the grid after rectification to or battery dc can be converted into voltage and frequency are relatively stable communication power, its function is good or bad directly affect the output of the UPS uninterruptible power supply function index. IGBT inverter high work frequency ( 20 khz) The filter is small in size, low noise and high reliability. < / p> < p> the bypass switch is for progress UPS uninterruptible power supply, the reliability of the system operation and can bear the load of instantaneous overload or short circuit. For UPS uninterruptible power supply inverter selection of electronic devices, such as IGBT tube overload ability is only 125%, when there is overload or short circuit fault in UPS power supply system, UPS power supply will take the initiative to switch to bypass, in order to maintain the inverter of UPS power supply will not damage due to overload. < / p> < p> KEBOUPS to bypass the power supply, power supply system is directly by the mains supply load, due to the large capacity of electric system can provide meet the moment, the overload or short circuit circuit breaker tripping, stay system after excision of overload or short circuit loop, the bypass switch will continue for the initiative back to the inverter load power supply to the other. < / p> < p> < / p>
