Answer Posted / raju
In ONLINE UPS, the load is always connected to
inverter output only in both the cases, whether normal
power supply is available or not.
In OFFLINE UPS, Inverter output is connected to load only
when normal AC power supply fails, means when AC power is
available it is directly goes to output.
