The Eaton 9SX 2000i is a double-conversion (true online) uninterruptible power supply rated at 2000VA, built in a tower form factor for 200-240V mains. Because it's online rather than line-interactive, it continuously runs the load through its inverter, so on a power failure or a load-shedding-style outage there's zero transfer time to battery — a step up in protection over cheaper line-interactive UPS units, aimed at servers, networking gear or other equipment that can't tolerate even a brief power blip. 2000VA is enough to carry a small server, a rack of networking kit, or several desktop workstations for a bridging runtime, extendable with Eaton's external battery modules for longer autonomy. The listing doesn't specify exact runtime at full load or rack-convertibility, so that should be confirmed against Eaton's 9SX datasheet.
