Uninterruptible Power Supply threads?

The SUA1500 and the 1500TLV both use the RBC7. The difference in capacity doesn't mean an increase in run time. What the extra 80W means is that it can be loaded up an extra 80W, but the run time will not be any longer.

Max Capacity SUA1500 = 980W (at the same time)
Max Capcacity 1500TLV = 1050W (at the same time)


Hope that helps to explain it. Let me know if it just confused everything more.

It's just a more efficient inverter = less power gets wasted as heat (which translates to more expensive to produce).

The consumer models (RS, LS, CS @ 1500VA) are less efficient than that of the SUA1500 (865W vs. 980W), and use cheaper batteries.

RBC7 = 12V, 17Ah (~$75)
RBC109 = 12V, 9Ah (~$40)

I think part of the problem is that APC doesn't particularly care for the home consumer, that's why they make the home units so much flimsier. They don't want to lose 90% of their data center market share, so they make those units much better.

Anyone have several XS/RS 1000's fail on them with the famed "overload" error?

Completely different markets with different needs. Their respective users have different budgets that play a substantial role as well (most users don't even have a UPS, let alone can understand the need for one that can have an MSRP of over $1000USD).

The enterprise market (workstations and servers owned by corporations primarily) are where the real money is for APC (Tripp Lite and Eaton as well), as they realize the need for such a unit, and are willing to pay for it.

So would you think it's fair to say that the quality of the enterprise units is far better than the home units?

I think that would be a fair assessment for anything claiming to be 'enterprise class'. There are some outstanding pro-sumer products (Western Digital Black Caviar drives come to mind), but enterprise elevates it just bit more.

One exception for me is anything from LaCie. They can claim to be enterprise, but I wouldn't trust their products with my enemy's money.
 
I got impatient waiting for my tlv unit from excessups, and for the time being a bought an APC 1500VA XS UPS from best buy and it is completely and utterly silent. Just saying.

Because it's running off fo the wall unless the voltage goes low enough to trigger the unit to switch to the battery and run the DC through the inverter. Once that happens, a fan will kick in to cool the inverter.

It's completely and utterly silent because the APC XS 1500 doesn't even have a fan! :)
 
just got an email from excessups.com here is the gist of it.


Hi Philip,


The SU1000RMNET was taking too long to get ready, they were having problems with the units. I upgraded you at no extra cost to the SU1000RM2U, it's a newer better unit.

We've shipped out your order with FedEx Ground, it's on the way now. The tracking numbers are: 59200**********, 59200**********. The order should be delivered tomorrow.

Please let me know how it works out when the units gets there. If you have any questions, please get in touch with me right away.



Thanks,
Tony

Nice Guy to do business with. I grabbed two refurbished pieces. One for the Macpro the other for the iMac. He gave me a small discount on top of the refurbished price. They ship out of Buffalo I am in NJ so the shipping was decent. I have a lot of meters and will test them a bit in the next few days. Phil
 
Well, the APC 1500VA TLV arrived the morning of the day before estimated delivery, so I have it here and just set it up. Deep scratches on the top of the unit, but I didnt buy it to look pretty. It doesnt have a convenient display to tell me stuff, but I guess that's fine. Came with no instructions, but the setup seemed easy enough.

It doesnt look like this will work out for me. There is a sort of power/electricity buzz when I put my ear close to it, but that's not the problem. There seems to be something constantly spinning that makes plenty of noise. It sounds like a fan I guess, but reminds me of a hard drive because it will stop spinning for about a second every so often. I mean my Mac Pro isnt dead silent either, but this is pretty high pitched, so it's rather noticeable.

Ah well, guess I'll be returning it.

Yes they do. I have this one and it's brother, the 1300 and when my power goes out or dips, the fans spin up enough along with the alarm to hear it in the other room. No big deal to me as I know my computers are protected. Worked great on my Mac pro (just sold) and my iMac. Not sure if these would be big enough for the new 12 core though. Depends how much time you want in reserve. I got about 25 minutes on my Mac pro.
 
I've been running a CyberPower CP1350AVRLCD for almost two years. It's completely silent unless you're actually running on battery power -- then the alarm and fan kick on which are somewhat loud. It's got an LCD with all the readout info you want, and OS X recognizes it without any additional driver install. So far I have no complaints but I probably would get the CP1500 if I was buying again cause the CP1350 only gives me about 20 minutes of backup power.

Can you describe the sound a bit better? I am not sure what you are describing whether it's a fan noise or if it's a transformer sound. Can you separate the UPS from the Mac Pro so you know where the sound is coming from?
 
I can differentiate between sound coming from the Mac Pro and the UPS. The Mac Pro, on the whole, is noisier, although they are both fairly quiet.

On closer examination, I think I was speaking of the same sound coming from the UPS. It just sounds different when I press my ear to the top compared to the sound coming out of the vent. It's probably not a fan, since if I listen long enough, I can hear the fan make slight noises as the RPM drops for a second and then picks up (the fan is silent otherwise I guess.)

Here is the noise recorded with my iPhone. You can hear the buzz pretty clearly. The noise is pretty hard to hear from a few feet away, but since it is a fairly high frequency, it cuts through other white noise.

The two pieces arrived. they are a bit old looking. with refurbished no big deal. One unit is going out of site and thats a good thing as it has a running fan. the 2u unit is about 20 by 20 inches it is dead quiet when not running off the battery. it is noisy with the battery running during a plug pull black out test. fan is noisy but since this is for blackouts who cares. My savings are 60 percent off new retail price.

I need to rethink placement for the flatter 2ru unit the sm1000rm2u is as deep as it is wide..

Congratulations on the 12 core! When are you getting it in? I'd love to see what happens when you boot up with the 1300.

The biggest noise you hear when you pull the plug is the humming of the transformer. Are you able to hear the fan spin above the transformer noise? UPSs should be dead quiet when in idle operating mode. When the power goes out, that's when the noise comes.
