  • Size

    Tower

    Form that resembles a classic tower (Tower case) computer. Suitable for spaces with sufficient height and depth. Usually larger and more powerful UPS.

  • AC Outlets

    The AC outlets are the power output sockets where you connect the devices you want to protect and supply with power through the UPS.

  • Type

    (VI) Line-Interactive

    They continuously adjust the output voltage through the automatic voltage regulator. They offer satisfactory protection against voltage fluctuations. In case of a power outage, the switch to battery mode is made in minimal time, compared to a standby UPS.

  • Plug Type

    Schuko

    European grounded socket, type F.

  • Power (Watt)

    Indicates the actual power that the UPS can provide to devices. It is expressed in Watts (W) and is the most reliable indicator to know how much load (e.g. PC, monitors, router) it can support.

Power (VA)
850 VA

Power (VA)

Indicates the maximum electrical load the UPS can support, measured in Volt-Amperes (VA). This is the apparent power of the UPS and is used to compare the size/class of UPS units.

Note: VA is not the actual power that devices can consume. To check what you can connect, always check the Power (W) as well.

Usage Examples:

  • 800VA 480–560 W Router, modem, small computer, LED lighting
  • 1000VA 600–700 W Office PC with monitor, small printer, NAS
  • 1500VA 900–1050 W Powerful PC or gaming PC, multiple office devices
  • 2000VA 1200–1400 W Workstation, small server, cash register + POS
  • 3000VA 1800–2100 W Server, rack equipment, professional labs, studio

    It definitely protects against surges. But during sudden drops it shuts off. It did this from the beginning when it was new and still does now, 19-5-2026, even after changing the battery after purchase on 30-7-2024.
