Correct option is A
On-line UPS-
The
static switch is the key component that differentiates an
online UPS from an
offline UPS:
Online UPS:
· The load is always powered through the inverter, which continuously supplies conditioned power.
· The static switch transfers the load to bypass the supply only in case of inverter failure or overload.
Off Line UPS-
Offline UPS:
· The load is powered directly from the mains during normal operation, and the inverter is activated only during a power failure.
· A static switch is not always present or actively involved in power routing.
