Uninterruptable Power Supply
In a perfect world, your power would never go out, or have surges that could stop your appliances from working. We don’t live in a perfect world, though: we live in a world of power glitches, of brownouts and downed power lines.
For some appliances, these are more than just annoyances: an unexpected power outage can corrupt the data on your computer or send your home security system into a panic. And medical devices like CPAPs can end up choking you if the power unexpectedly stops.
So, what can you do to protect your devices from these problems? Install an Uninterruptible Power Supply, or UPS.
