Question 1

What would the expected operating time be at 75% load on this unit? I've installed several of these but it's been awhile and I don't remember the number.

Thanks!

According to APC's website:

At 700W (70% Load) - expected runtime is 14 minutes.
At 800W (80% Load), it would be 11 minutes.

That is going to be absolute maximum.  Personally, I wouldn't load one up to 75%. I would get something a bit larger

Question 2

How loud is the SMT1500RM2U? I have the SMT1500 floorstander but want a rackmount version. Would you recommend it for home use?

Accepted Answer

I believe that it does make a small sound but it is very quiet.  It certainly doesn't have any big noisy fans (like a POE Switch or a server does).  I think it would be fine for home use - Just make sure it is safely stored.  The unit is very heavy and you don't want it to fall!  : )

Question 3

Does the Smart-UPS SMT1500RM2U come with rails to mount in a 19" relay rack?

Accepted Answer

Yes and no..  The L brackets that are used to lock it down in a 4 port rack can be attached to the apc  in / about the middle of the unit which will permit mounting in a 2 post, however if your relay rack is a wall mount, seek alternative mounting options as these units aren't light

Question 4

Will this UPS work the same in Asia or Europe?

Accepted Answer

It's okay with either 50 or 60Hz but the spec'd supply range is 84-144V, so it probably wouldn't enjoy being plugged into 220/240.
