What is the difference between online ups and offline ups?

Answer Posted / gurumurthi

In Online UPS the main supply passes through Battery as well as inverter to the load at time.

But in Offline UPS the main supply passes direct to load & to the battery section & bypasses the inverter section. Once the mains fails the supply is feed from battery section.
