A UPS or "Uninterrupted Power Supply" is a device which converts mains power to DC then back to mains power. At the DC level, energy is stored in batteries or capacitors so that when there is an interru[tion to the normal mains supply, energy is taken from the power storage devices and delivered to the output so that the output is always at the cvorrect mains voltage, surge free.

∙ 12y agoAn Uninterruptible Power Supply (UPS) contains an internal rechargeable battery that gets charged from the powerline then gets used to generate line power to the load when the powerline fails. To accomplish thata, they also contain an inverter, an electronic device capable of generating 110/220v AC from battery-level DC voltage. There are different types of UPS depending on how and when the power generation occures, and how precisely sine wave-shaped AC voltage they produce. Powerline AC voltage is supposed to be a sine-wave, and it mostly is. UPS-generated AC is usually a lot less sine-shaped and some devices care more about that then others. Generally, computer supplies couldn't care less, so cheap UPS-es don't bother much with that.
