Explain how an on-line UPS works and why their advantages when compared to off-line UPS units.
What will be an ideal response?
An on-line UPS is always running off its battery while the main power runs the battery charger. An advantage of an on-line UPS is that it is not affected by dips or sags in voltage. An on-line UPS can clean the electrical power before it reaches the server to ensure that a correct and constant level of power is delivered to the server. The on- line UPS also can serve as a surge protector, which keeps intense spikes of electrical current, common during thunderstorms, from reaching systems.
