That little server in the corner or the VoIP phone system that keeps dropping calls during a storm — you don't need a room full of gear to protect it. This APC Smart-UPS X is a 2U unit that racks up or stands on its own feet (removable support feet included). 1500VA / 1200W of pure sinewave backup. Eight C13 outlets plus two IEC jumper cables. At full load you've got 5 minutes 45 seconds — enough to shut down cleanly or ride through a short outage. SmartSlot on the back takes an optional Network Management Card if you want remote monitoring and PowerChute Business Edition for unattended shutdowns. Extended runtime capability with external battery packs (SMX039-2). Lead-acid battery inside; replacement is APCRBC115. 40 dBA — quiet enough for a staffed office. RS-232 and USB cables in the box
