Line Interactive UPS: Regulates the power as it falls and surges. They offer protection against surges, sags, brownouts, spikes, radio and electrical interferences. If the spike or sag is severe (over 24V above or below nominal 240V output), the UPS will transfer the load to the batteries. The reason why it is called a Line Interactive UPS is because it only interacts when there are fluctuations in the power line.
