How long does the 5E1200UF last on battery with a desktop PC?
About 40 minutes with a single PC, and 15 minutes if you connect two. These are the typical backup times stated for a complete workstation: they shrink with a large monitor, more power-hungry hardware or a battery nearing the end of its life.
What does the AVR regulator do when the mains voltage drops or rises?
It corrects the voltage itself without switching to battery, over an input range of 140 to 300 V. As long as the power stays within this window, the battery is not used and is kept for genuine power cuts: that is the whole point of a double-boost line-interactive UPS where the grid fluctuates.
Is the UPS noisy in an office or a living space?
No, it has no fan at all: the fanless design covers the range up to 1200 VA, and the noise level stays below 25 dBA. You can place it under a desk, next to a workstation or in a living room without hearing it run.
Can the UPS be switched on when there is no power at all?
Yes, it supports cold start: it switches on and powers your devices from the battery even with no mains present. Its batteries are also kept charged at all times, even when the unit is switched off, so they are full when the power cut comes.
What happens if the power cut lasts longer than the battery?
The UPS shuts down once the battery is empty, then restarts on its own when power returns: the automatic restart function restores power after a full discharge. Your devices start up again without anyone having to come back and press a button.
Do I need to install software for the PC to shut down properly?
No. The USB port integrates automatically with the power management of Windows, macOS and Linux: the system recognises the UPS and triggers the safe shutdown on its own. The Eaton UPS Companion software is an optional extra for analysing consumption and adjusting settings.
How can I tell that the UPS battery is reaching the end of its life?
The UPS runs an automatic battery test and triggers a replacement alarm when the battery weakens. So you are warned in advance, instead of discovering the problem on the day of a power cut, when the protection no longer does its job.
What is the difference between the stated 1200 VA and 660 W?
The 1200 VA is the apparent power, the 660 W the power actually available. It is this second figure that you need to compare with your equipment: add up the watts of the tower unit, the monitor and the broadband router, and keep a margin below 660 W to maintain the stated runtime.
Can a TV, a games console or a NAS be plugged into it?
Yes. Intended uses range from the workstation and its peripherals to internet routers and NAS units, including TVs, games consoles, home security systems and point-of-sale terminals. The only limit is power: add up the watts and stay below the 660 W of usable power.
At what voltage does the UPS deliver power?
230 V, adjustable to 220, 230 or 240 V. On the input side, it accepts 220 to 240 V nominal and a frequency of 50/60 Hz over an operating range of 46 to 65 Hz. This output setting is made once at installation, according to the voltage your equipment expects.
How much space does the Eaton 5E 1200 take up, and how much does it weigh?
A tower format 330 mm long, 180 mm high and 133 mm wide, weighing 8.5 kg. It stands on the floor under a desk or against the tower unit; at this weight, provide a stable base rather than a wall shelf.
How can I tell that this UPS meets safety standards?
It is CE-certified by the external body TÜV, to the international standards IEC/EN 62040-1, 62040-2 and 62040-3, and carries the CB, EAC, UKCA, Cm and Ukr markings. On a device that is permanently plugged in and filled with batteries, this third-party-verified compliance really matters.
Is the Eaton 5E1200UF UPS new and under warranty?
Yes, new equipment, with the invoice serving as the warranty document, for a period of
2 years. The
full datasheet sets out the backup times model by model and all the electrical values.
