  • I have a real simple questions for all of you in the know.

    This is probally answered someplace but for the live of me could not find it...

    Thanks a lot

    The main difference between the BackUPS and SmartUPS is the UPS topology they are built on.
    BackUPS = standby
    SmartUPS (SUA units) = line interactive
    SmartUPS (SURT units) = double conversion online

    Please see the following kbase for a deeper discussion on this:

    For simplicity's sake SmartUPS are generally favorable (yet pricier) for the following reasons:
    - Faster transfer time to battery
    - AVR (automatic voltage regulation) - all SmartUPS have boost and trim features to enhance the quality of utility electric without switching to battery. Note: The BR and BX BackUPS lines also have this
    - Better reliability (hence smartups are aimed at server applications, while backups are aimed at workstation computing)
    - Higher compatibility w/ generator use
    - Ease of interpretation, configuration (all SmartUPS have several LED charts to indicate current status, load, battery charge etc.)

    Of course there could be a much more in depth discussion here, but I hope I started you in the right direction

  • THank you for a response to my question. I have a smartUPS 1000 that has died (I have tried replaing the batteries and it does nothing) so I wanted to purchase new UPS and the backupUPS's are so much less expensive but after reading this, I am thinking that I should just bite the bullet and purchase new SmartUPS...

    Thanks again

  • Hi,
    are there any specific applications, I mean industrial applications where SmartUPS are used? Or what would be some server applications - as you specify - SmartUPS are used in the server applications?
