We're about to order a Dell 48U Rack and in the quote they've got 2 5600W UPS's. These are Dell branded UPS's, not APC's like they use to provide.

Has anyone got any of these UPS's? Are they any good? Comments?

They are an exceptional price so if there isn't any strongly negative feedback, this is probably the way to go. Otherwise I will dump the UPS's out and buy APC's, which will push the price up a bit...

Thanks.

Hi,

The Dell is actually a re-badged Eaton UPS now. They are a semi-custom variation made just for Dell, very similar to the Eaton 9135 (6kVA) UPS.

The price on the Dell's is fantastic and should provide a nice reliable solution.

One thing we have noticed from this particular variation though is they do need to be installed in a reasonable environment, they are definitely an "IT Rack Only" UPS. There are no air diverters behind the fans in the front of the UPS and it causes a bit of excess moisture to build up on the circuit board directly behind the fan.

In saying this you would see similar issues with the APC Smart-UPS RT Range.

Awesome. Thanks for the feedback.

Based on that I will plow ahead with the purchased.

Before you pill the trigger and buy one, where is your kit located? Is it onsite or collocated? If it's collocated then you shouldn't place a second UPS in front of the one(s) your data center provides.

If these are Eaton OEM then I would highly recommend them..

In my experience their battery management is extremely kind to the battery packs.
The use of 'rest' periods gives a big increase in reliable life span compared to most other systems that run continuous float charge..
