Answer Posted / vijay prashanth t
Online UPS: We can also define this as true online, double
conversion UPS. This UPS will convert the AC power in to DC
and again DC to AC. And thats why, this is called as double
conversion UPS. The output of an online ups will be pure
sine wave always. The connected load is always in Inverter.
Offline UPS: This UPS will regulate only the voltage
tolerance and there will not be any protection for spike or
frequency tolerance. The output of this UPS will not be a
pure sine wave. The connected load is in Inverter only when
the power fails.
