Unstable UPS power

[SinisterSmiley]

Hi everyone, 
I have a bit of an Electrical / UPS question. Hope its fine under Power supply section.

I bought a brand new 3000VA UPS to help power my Computer with a 800W Corsair Gold PSU. this is directly plugged in via Kettle plug
it also powers a small router for Wi-Fi.  This is plugged in with a kettle plug to standard 3 point wall socket so the ac power adapter can be plugged in. 

Now my power seems a bit unstable at times and dips to 207 VAC from the wall socket, the UPS kicks in and tries to correct this, but shows that it is going up to about 247 - 253 VAC (which is higher than the common 240 VAC of most appliances) the UPS says it will stay within 10% of margins on packaging
All I really wanted to know was if this is something to be worried about for damage to Computer and Router? Is it maybe a miss reading on the little built in monitor on the UPS?

Thanks for any help  

Cheers

Nothing to worry about.  Anything below that 10% variance shouldn't matter--especially if it's a combination UPS/surge protector.

What kind of UPS is it?

Also how are you measuring the voltage, using a voltmeter or via software? software can be inaccurate. 

UPS Spec Sheet.pdfI attached the spec sheet of the UPS, its the 3000VA version. 

I am looking at the onboard LCD display showing the input and output Voltage.

I did wonder if it was accurate. It's brand new as well. bought it last week.

Power directly from the utility is required to be 230 V ±10%, so anything from 207 to 253 V is considered normal voltage that could come out of a wall somewhere. All devices will be designed to handle this range without problem.

3000VA and only 1800W? well that's inefficient. Voltages are normal like Glenwing said but I'd measure with a voltmeter just in case, to make sure the device's measuring is correct.

It's a bit more of a budget UPS as far as i can see in comparison to more expensive brands like APC, I don't think i will get close to that power draw anyways and its a huge improvement over my last UPS or having no UPS at all with all the power issues we are having in South Africa with load shedding. I might save up and rather get a Inverter + battery at some stage.

Not really wanting to download random PDFs from a forum.  Not sure why you couldn't just post a make/model or a link.

 

At any rate, the higher voltage is actually fine.  If anything, it's better because higher voltage is lower current.  I wouldn't worry about it.

thought it would be easier as its the full spec sheet i got from the manufacturer.

its a  LinkQnet UPS-INT-3000VA-LQ-K
