On-line type UPS at the municipal gives or get an electric shock normal, be proceeded by municipal electricity to commutate to provide the direct current electric voltage change the inverter works, being changed by inverter face to load to provide the alternate current, when the municipal gives or get an electric shock the abnormality, inverter changes the machine be provided by battery energy, inverter changes the machine to be placed in the work appearance always, guaranteeing to have no to interrupted the exportation. Its characteristics is, have the very wide importation electric voltage scope, basic have no to cut over time and output the electric voltage the stability the accuracy high, special in keeping with request the higher situation to the power supply, but the cost is higher.
