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.
