LinkQnet 1KVA XR Online Tower UPS
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.

Continuous Power Protection
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%.
Flexible Installation and Monitoring
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.
Key Features:
- 1,000 VA / 900 W capacity for compatible IT, networking and electronic equipment.
- True online double-conversion topology provides a pure sine wave output and 0 ms mains-to-battery transfer time.
- Extended-run design works with a separately purchased external 24 V battery solution.
- Wide 110–300 V AC input range provides greater tolerance of fluctuating utility power.
- Selectable 208, 220, 230 or 240 V AC output supports different installation requirements.
- LCD monitoring, ECO mode, generator compatibility and cold-start capability provide flexible operation.
- Built-in protection covers short circuits, overload, overheating, battery overcharge and over-discharge, low output voltage and fan faults.
Important Battery Information:
- This UPS is supplied without batteries.
- A compatible external 24 V battery solution is required for backup operation.
- Available runtime depends on the connected load and the capacity and condition of the selected batteries.
- Battery selection and installation should be completed by a suitably qualified installer.
