The LinkQnet 1kVA XR Online Tower UPS provides continuous power conditioning for compatible computers, networking hardware and other sensitive electronic equipment. Its true online double-conversion design delivers a regulated pure sine wave output with no transfer delay when moving from mains power to battery operation.
This extended-run model uses an external 24 V battery solution, allowing the battery capacity to be selected according to the required backup time. Please note that batteries are not included and must be correctly specified and installed for the intended application.

Online double-conversion technology isolates connected equipment from common mains power disturbances while maintaining a stable output. The UPS supports selectable 208, 220, 230 or 240 V output and regulates output voltage to within ±1%.
A wide 110—300 V AC input range helps the UPS continue operating through varying utility conditions, while generator compatibility supports alternative power arrangements. Its LCD interface displays essential operating information, including input and output values, load percentage, battery voltage, internal temperature and estimated remaining backup time.
