I am wondering if anyone has a recommendation on a good but affordable 120v or 240v UPS. I can use either source.

I needs to be 900 or more watts.

I currently use:

2xCyberpower CP1350AVRLCD (1 is dying and glitchy as hell and only runs monitors and knick-knack)

1x Tripplite SMX1500LCDT
https://www.tripplite.com/support/smx1500lcdt

They both are digital sinewave so not clean/good power source when on battery. Very affordable but not ideal.

Any advice or opinions?

Also is online vs interactive that big of a deal? Assuming reasonable quality of power?


These are some options I have found on Tripp-lite. Any thoughts or different options?

CDW often has very favorable prices on UPS's they are getting rid of. Check SamirD 's Hot Deals thread.
 
An old APC Smart UPS the black ones (like an SUA1500) can be found on eBay and craigslist for cheap. Throw new batteries in them and they are a great product and will last YEARS problem free.

And Provantage does too in their open box section as well. In fact, after CDW didn't pack 2 UPS shipments well and both arrived damaged, I found a 2200va $700+ rack unit at Provantage for $150 shipped--and they packed it right. It probably cost Provantage $50 in just shipping since that thing was so heavy, but it's still working away today.

As far as line-interactivity, it depends on how important the load is. The 2200va unit was a backup for my mom's breathing machine that she couldn't take being without for more than about 10 seconds, so it was almost literally life or death critical. Plus that $10k machine wasn't ours so I didn't want us to have to pay for it in case our power zapped it. So for that I went pure sine-wave, which is my preference if I can find it in the time constraint I'm up against. I can always find a solid deal if I wait long enough.

And don't forget that you can also find genuine batteries cheap, like this deal on batteries for the 1350PFCLCD Sinewave model for $28 (doesn't fit yours--I checked):
https://www.cdw.com/product/cyberpower-ups-repl-batt-12v-7ah-2pk/5535561?pfm=srh

If you don't mind having a bunch of units, I found these Eaton 700va line interactive units for a steal right now at $34 because they're 230v:
https://www.cdw.com/product/eaton-5s-global-700va-tower-208-230v/5512322?pfm=srh
https://www.cdw.com/product/eaton-5s-global-700va-tower-208-230v/5514799?pfm=srh
https://www.cdw.com/product/eaton-5s-global-700va-tower-208-230v/5512336?pfm=srh
https://www.cdw.com/product/eaton-5s-global-700va-tower-208-230v/5514798?pfm=srh
https://www.cdw.com/product/eaton-5s-global-700va-tower-208-230v/5514796?pfm=srh

And then there's this Liebert 1500va model that's not sine wave, but cheaper than batteries at $54:
https://www.cdw.com/product/vtv-psa5-1.5kva-900w-lcd-ups-10out/5535669?pfm=srh

Now if you want sine-wave, there's a good 2000va one here for $116 that's normally $400:
https://www.cdw.com/product/cyberpower-smart-app-lcd-2200va-bst/5525108?pfm=srh

But I have to warn you that this is the exact same model that arrived with the entire front face smashed to pieces due to improper packing, and I'm still working on a return with CDW. I can get mine to work (and did for a while as my mom needed it), and I guess the batteries alone are worth what I paid for it if I have to recoup my money otherwise, but it's the hassle. And it's not a light unit at all.

Generally, the larger the capacity, the heavier it will be and the greater chances for damage.

Still, when you can pick up $900 3000va units like these for $346:
https://www.cdw.com/product/cyberpower-ups-3000va-smart-app2400w/5539711?pfm=srh
https://www.cdw.com/product/cyberpower-ups-3000va-smart-app2400w/5539716?pfm=srh

The price on this Liebert 2000va 1800w unit is just insanely cheap at $523 when it is $1300+ anywhere else, and if you're willing to wait a week or so it should drop to $479:
https://www.cdw.com/product/liebert-gxt4-2kva-ups-rck-twr-120v/5536871?pfm=srh

And if you're willing to go all out and use the 230v to get some serious 5000/6000va units, you'll find this $3700 APC unit currently at $2460 and this Eaton $3500 unit at $2830:
https://www.cdw.com/product/apc-smart-ups-srt-5000va-rm-208v-bs/5558990?pfm=srh
https://www.cdw.com/product/eaton-9px-6k-ups-l6-30p-2xl6-30r-bs/5567007?pfm=srh

https://www.cdw.com/product/eaton-9px-6k-ups-l6-30p-2xl6-30r-bs/5566905?pfm=srh

And an ungodly 10,000va apc unit that's normally $6300+ is in the outlet for $4837, which I'm sure is so heavy it will require shipping as freight: :eek:
https://www.cdw.com/product/apc-smart-ups-srt-10kva-rm-230v-bst/5571728?pfm=srh

Provantage didn't have any deals more than 50% off, but the old PC Connection (now Connection) has a pretty nice APC 1000va sine wave unit for $100 shipped:

A lot of the older sine wave APC units were made really, really well. I put a 1000va one into service that was bought in the 2000s and sat for probably a decade after its first battery died and it did terrific with a genuine apc battery until the battery recently died. And I forgot to watch the outlet for the battery until this thread, so thank you for that! :)
 
"Also is online vs interactive that big of a deal? Assuming reasonable quality of power?"
- Yes, it's the big deal quality-wise, of course assuming a decent manufacturer and implementation. The main reason - the zero switching time and the constant sinewave at the output outlet no matter what's comes from the wall.
Drawbacks - constant noise from the ever running fan(s), and a bit more power consumption by the UPS itself because its inverters are 24/7 and the constant double conversion and heat losses. And the price :) .
 
Oh and something else to watch when running a high load (2000va+) is to watch how much you are taxing your circuit breaker. A lot of UPSes have a voltage display that lets you know the voltage coming in--check this before putting on a load and after to see how much you're taxing the circuit (making it hot). If you're seeing voltage drops of 5v or more, you should split the load on separate circuits if possible to avoid any fire hazards.

my problem on my "240v" line is it runs 250-255v because my current UPS is only 900w so It doesnt touch the 3kw wall rating lol so it frequently bucks the voltage. I don't even have enough load to get it off nominal voltage hahahah.

Thats why I want to get one of these 1.8-2kw ones. The online ones would be super sweet since my desktop and server and monitors are like 5 grand in total o_O

EDIT: so what do you recommend of those for 240v and online. Any recommendations?
 
Well. In addition to Samir's thread, check local ads like Craigslist. I got an apc 3000 xlm with four extended battery modules, with all good batteries, for I think $50 or so.

If you are relying on your load to regulate your voltage you either seriously undersized the conductors, have a bad connection somewhere that’s likely to start a fire, or you should scream at the utility for using the wrong transformer tap.

Your voltage at the wall does change under load - that’s physics, but you want that change to be as minimal as possible.

Also - Eaton UPSes are what we are turning to now at work.

I wish I had that problem! Actually, I just wish I had that 240v line. :D

So knowing what you've got now and how much capacity you have (jealous!), I'd recommend some of the higher dollar units towards the bottom of the list that I found. Also honestly, once you get up into that capacity and price range, everything is good stuff no matter what brand as it's designed for enterprise use. :)

https://www.cdw.com/product/eaton-9px-3000va-gl-rt-208v-bstk/5554911?pfm=srh - $1389 outlet vs $2100+
https://www.cdw.com/product/tripp-3kva-online-ups-rm-208-240v-b/5574638?pfm=srh - $1040 outlet vs $1300+
https://www.cdw.com/product/eaton-2200va-twr-rack-mountable-ups/5571620?pfm=srh - $1039 outlet vs $1300+
https://www.cdw.com/product/hpe-r-t3000-g5-hv-na-jp-ups-bstk/5541586?pfm=srh - $564 outlet vs $1150+

The HP and Eaton ones represent the best values and I think they're both near the bottom of their discount cycle so this is about as cheap as they will get.

Because you have more voltage coming through, you may also want to pick up some of these smaller units to utilize the extra capacity. These are actually 230v sine-wave units for $267:

us runs on 120v but no load is 125v* so 2x125v equals 250v...how is that hard to comprehend?
Actually, it is as high as 128v where I am at if true 0 loads.

Is the T3000 online? looking at specs if it is it seems fairly loose compared to the Tripp-lite. Tripp-lite has 2% and this is 6-10% +/-
https://h20195.www2.hpe.com/v2/GetD...kspecs&doclang=EN_US&searchquery=&cc=au&lc=en

eaton has 1% supposedly. Are there any reviews for these or are these too nichey to have reviews?

I think they meant 250v.

I see 120v on some of the outlets around my parents house, but most are 118/119v. If I heavily load up a segment, I've seen as low as 105v, but then within 10 minutes the breaker tripped and entire circuit breaker panel was super hot to the touch--not a good scenario. Now, I won't load any branch up to where the voltage even approaches 110V.

yes typo. I fixed the original post. In IL I always see 125v+/- as normal voltage with 0 load and it doesnt hit 120v until at least 500 watts. I have seen 110v or so but that's like 2000w+ on 120v 15amp line, which is a stupid thing to do.

Any opinions on the T3000 and its quality verse the Tripp-lite or easton?

I think the guys on the servethehome forum might have some feedback here. This is equipment I could never afford or need at this point, so I'm a bit out of my league. Looking at the specs at both, they're all top notch enterprise gear, but there may be certain specifics that work better for your setup, so keep digging. (y)

question. Do you think those Eatons will come down more? I really dig the price on the HP but it doesn't have as nice of power conditioning. (but crazy affordable)

The HP is at 50% of normal price whereas the 3000va Eaton is 60%something and the 2200va Eaton is just barely discounted at this point. My guess is that the big Eaton has one more drop, possibly two (if it's two the second will be just a hair of a drop--I've seen that a few times as a last ditch effort before liquidation), while the little Eaton probably has at least 3-4 left in it before it his bottom.

Remember, there is a return period, so worst case you can buy the HP and wait for the Eaton to come down to a price you want. If it doesn't, you've got the HP, if it does, you can return the HP, but there's a cost in doing that since shipping won't be cheap on heavy items like that.

wow awesome thanks for the info. I'll keep eyeing the eaton. I dont have to buy this second so if that 1k one can come down to 700 or less i'll buy it in a heartbeat.

I would love a 3k one but i can't do that much money :/

Any idea on what the eaton (2k one) might drop to?

You're welcome. I understand. I think there's a good shot of both the trip-lite and eaton ones that are normally around $1300 to come down to $700, but it will be a bit of a gamble since someone that does need one will grab it before it hits that low.

It's weird, sometimes really high dollar stuff sits there until it gets pulled and goes to the liquidation pallet, and other times it's gone so fast even when it's only dropped once or twice (so about 10-15% less than regular price). Supply and demand I guess.

hey i made this thread and wasn't sure if you could help. A buddy of mine has me worried my setup might be wrong like the electrician installed the power line wrong. I am hoping he is mistake lol

Its down to $8xx. I hope it drops once more!!!!!!

Unfortunately, I know nothing about 240v power except that my dryer runs on it and you can use to charge a Tesla. :D

But that thread was awesome and I learned a lot--lots of super-smart people on here. (y)

Yep, and I think it will hit lower than that. It's a game though, it can hit lower and lower until *poof* someone else bought it or it got sent out for liquidation and is no longer for sale. :eek:

do you have any historical knowledge on this? Like on these type of UPSes? How often do they show up? Of I can wait 1-3 months is it likely more show up?

Also I forgot what you said. How would I buy and do pick up on one of the UPSes at Vernon hills IL? I live in western Chicago suburbs so driving and saving the cash would be worth it to me.
