The APC Easy UPS On-Line SRV 2000VA is a rack-mount (RM), double-conversion online UPS rated at 2000VA/1800W for 230V systems, built to keep servers and network gear running through outages with a clean, regulated sine-wave output rather than the switch-over delay of a line-interactive design. This unit comes with an extended-runtime battery pack for longer backup time than the base internal battery alone would give, four C13 power outlets for connecting rack equipment, and a rail kit for mounting it into a standard server rack. It carries a 2-year warranty — the 'Easy' range sits below APC's higher-end Smart-UPS SRT line as a more budget-conscious online UPS for small server rooms and comms cabinets.
