    Accepted Solution

    let's see if I can put this in "real world" for you:

    #1 is essentially a workstation UPS.  It is 120volts, which is typical for US desktops (110v really).  it is a basic UPS, sets on the floor near or under a desk.

    #2 is essentially a server UPS.  It is 230 volts.  Your servers may or may not run on 230 volts (208v really), you would have to check the server(s) itself/themselves to determine power requirements.  Being rack mount it is meant to go directly into a rack where various servers can be plugged into it.

    That is it in a nutshell.  Any specific questions you were wondering about?
