The difference between on-line UPS and on-line interactive UPS

From the principle, the main difference between the backup UPS and online UPS is that the backup UPS in the utility only regulates the utility voltage, the inverter does not work, in a waiting state, when the utility anomalies, the backup UPS will quickly switch to the inverter state, will be the battery power inversion into alternating current on the load to continue to supply power, so the backup UPS in the utility to inverse the work of the conversion of a period of time, generally less than 10ms; and Taiqifeng online UPS is always in the working state after boot-up inverter, so in the abnormal transfer of battery discharges. Therefore, the backup UPS will have a conversion time when switching from utility to reverse operation, generally less than 10ms; and TECHFONT online UPS is always in the working state after the inverter is turned on, so there is no interruption time when the utility power is abnormal to the battery discharge, i.e., 0 interruptions. Online interactive UPS, is that in the input utility normal, UPS inverter in reverse work to charge the battery, in the utility abnormal inverter immediately into the inverter work, the battery pack voltage is converted to alternating current output, so online interactive UPS also have conversion time.
