I have that Eaton which works great. The fan is loud though.

Anything one can do about this feature? Kind of silly when I look at the original unit I got ( the "standard" ) vs their pro line with always on loud fan.

At this point I really can't recommend TescomSA:
  • Got 2x 1k mercury online UPSes (9 Oct 2018)
  • 1 failed within 19 days with DC Bus overload
  • I went to drop off and got a swap out (yesterday)
  • When I finally had the chance to open the box*
    • Serial number on the box doesn't match the unit inside
    • It's not the same mercury UPS as I had
    • And its loud whereas the original unit runs about silent
  • Then wrote service an email with questions which has gone unanswered
  • Now forwarded it back to their admin address
I'm considering going to bank for reversal of funds / opening up a proper complaint.

*Yes I suppose I could have opened the box on scene, if I failed somewhere it is here. Just trust no one or nothing and always double check if you have to redo someone's job for them.

The eaton's fan only goes on when its in a charge state. And as far as I know only the 2000VA one has a fan. So typically its off. If you fancy wiring an inline resistor you could quite it down a bit be reducing its RPM's as well. Its a minor issue I guess, and the Eaton name is pretty well respected for their quality.

I don't mind normal fan noise, like 240mm in your case or even GPU when it spins up now and then but consistent loud fan, louder than those fans 24.7 is a bit much.

I bought two smaller Eaton models recently and I have run into some issues:
1. The one unit wasn't able to handle a load which it should have been able to and just turned off. So I would over provision on this as much as you can.
2. The USB port on my one unit has a lot of issues with its connection becoming intermittent.

If this was for a more critical installation I would spend the extra money and go back to an APC unit.

That is my next option of the Tescom units doesn't workout as I originally thought they would. However I have tested one already by cutting the power and it was fine.
 
True, I too would spend the extra bucks and get an APC. Specifically something with a pure sine wave inverter. The eatons are good value though.
 
I am also looking for a 2000VA UPS that is not noisy. Electricity is pathetic where I stay and fluctuates a lot. The UPS must also give me some time to save and switch off.

To battle voltage fluctuations find a line-interactive one with a wide line input AVR range, it should be in specs. It is how I can help at the moment, busy on my own things.... Online UPS's usually have a wide AVR coming from a PFC circuit, but these are expensive.

Thanks. Im not too cluedup with electricity etc. Is possible to give me a link to an example. But I'll take a look....
 
I have an RTC so take heed of the following:
The beep on battery mode is super loud and very hard to turn off and keep off
Software is useless (although this is par at the low end)
Fan comes on randomly in charging mode, although it not too loud
 
I've had more UPS's over the years than I care to mention.

currently sitting with an utterly useless 3000VA Mistake (Mustek) UPS that needs 6 x batteries AGAIN..

I tossed a 1500VA APC Smart USP (rack mount) that blew a fuse or cap or popsickle??

APC UPS's are like Bentley's.
Fantastic when they break inside of motor plan.
Large heavy paperweights when they break outside of motor plan.


a UPS is fantastic if you want to manage graceful shutdowns that stop your RAID5 array from corrupting after a power failure but they're UTTERLY USELESS if you actually want to get some work done. (hours behind a keyboard, scanning & printing documents, while connected to the web)

& forget running a laser printer off a small UPS.
They just beep and shut down.
too much current.


So after bumping my head repeatedly against the "UPS wall" I decided to I invest in 2 x 150AH AGM deep cycle batteries and an inverter.

(added another 120AH battery later with a 130W solar panel + charger)

my heavy as *&^% battery babies now live comfortably in the garage & run my PC's (3), monitors AND fridge AND freezer AND 42" TV AND ONT AND router AND laser AND inkejt MFP - for an entire day (sun up to sun down).


or, they last the fridge + freezer + TV + streaming PC + internet + another laptop for an entire weekend.


WITH a couple of garage door open/close and 3 x odd coffee machine sessions thrown in for good measure.


actually, coming to think of it, I have a 3000VA Mistake (Mustek) UPS for sale (just needs 6 x 12V 7.2AH batteries and she's good to go)

Sure, that's the best way to do it, but you want a decent inverter. Something that can do a guaranteed pure sine wave.
 
I seriously doubt if my blatantly Chinese "pure sine wave inverter" is a real McCoy.

so far I've had no issue though.

just lucky.

.LOL.
One of UPS function is to protect equipment from power surges. A good one will sacrifice itself in a critical time. A poor one will survive, putting at risk the equipment it was supposed to protect. Keeping analogy with the car industry, a crash zone is to protect passengers. A poor, but strong car will survive on the impact, but a passenger dies.

In this real world I have seen more cases when UPS survived blowing up everything else than doing the right things.

Please pay respect to the UPS that died on duty, it deserves repair. Donate to sajunky :)
