Explanation
A UPS (Uninterruptible Power Supply) contains an internal battery that instantly takes over when utility power fails, giving users time to save work and properly shut down systems. It also conditions power and protects against surges. A surge suppressor only protects against voltage spikes, a line conditioner smooths power fluctuations but provides no backup, and an auto-switching power supply adapts to different input voltages but does not supply battery backup during outages.
