An online UPS converts incoming AC into DC, and the inverter turns it back into smooth AC. Because the equipment runs on the inverter all the time, nothing has to switch over when the mains fails – the battery takes the load unnoticed. Surges, sags and line noise stay behind the UPS and never reach sensitive electronics.
At 2000 VA the usable output is 1800 W, a power factor of 0.9. That is enough for, say, a server with a NAS, a network switch and a router, or a powerful workstation with two monitors. Four sockets cover a typical small server corner. Keep the combined draw below 1800 W and leave headroom so the UPS is not running at full load all the time.
According to the manufacturer, the maximum input voltage is 300 V. When the mains voltage rises, the UPS does not drop to battery straight away but evens it out with its online circuit. The battery is saved for real outages and wears less – which matters where the grid is uneven, such as in production spaces, rural areas or buildings with older wiring.
The unit weighs 17 kg, so it needs a solid base: the floor, a strong shelf or the lower part of a server cabinet. An online UPS runs continuously and gives off heat, so leave space around it for airflow and do not place it in a closed, warm recess.
Small businesses whose server, NAS and network equipment must keep running through a power cut; engineering and design studios where a powerful workstation must not shut down mid-task; and IT administrators who need an online UPS for an unstable grid that can power several devices at the same time.

The manufacturer does not specify a runtime. It depends on the load: with lower consumption, the UPS lasts longer on battery.
Up to four devices with a combined draw below 1800 W: for example, a server, a NAS, a switch and a router, or a workstation with its monitors. Laser printers and heaters should not be connected to a UPS.
A line-interactive UPS switches to battery during an outage, which takes a moment, and lets some mains disturbances through. An online UPS always feeds the equipment from the inverter, so there is no switchover and the power stays clean even on a poor grid.
