Should I choose a rackmount or tower UPS?

The shape orientation of the UPS and how it is installed are referred to as form factors. The majority of UPSs fall into one of two form factors: mounted or tower.

A mounted UPS can be mounted to a server rack or a wall. These are typically single-phase, but rack-mount UPSs are also available. A rack-mounted UPS is ideal for a company that wants to save space by consolidating equipment in a rack or enclosure or by utilising previously underutilised wall space.
