Online ups is also called double conversion ups. In online ups power supply, the inverter is always running. When input voltage is normal, the rectifier carries most of the load, convert AC to DC and begins charging the batteries, then the inverter transform DC to AC; when voltage fluctuation happens, the rectifier will cut off automatically, and the batteries will work, and the inverter works and invert the DC power from the batteries to AC power. There is no power transfer swtich for online ups.
Online ups is mianly used for the devices that are very sensitive to voltage fluctuation, such as IT equipment, communication equipment, laboratory devices, network devices and so on.
