APC Smart-UPS Ultra On-Line, 3000VA, Lithium-ion, Rack/Tower 1U, 120V, 5x 5-20R, 1x L5-30R NEMA Outlets, SmartConnect, Extended runtime, W/rail kit

The APC SRTL3KRM1UC is an on-line uninterruptible power supply that delivers 3000 volt-amperes and fits into just one rack unit. It can also stand upright as a tower when rack space is scarce. A Lithium-ion battery pack keeps the unit lighter than comparable lead-acid models and offers longer life as well as quicker recharge times.

True double-conversion technology continually conditions incoming power and produces a pure sine wave at the outlets, so connected equipment never notices a transition when utility power is lost. The UPS arrives with an L5-30P input plug and provides five 5-20R outlets together with one L5-30R outlet, letting you support both standard and higher current loads in the same installation.

The built-in SmartConnect Ethernet port links the UPS to EcoStruxure IT and other cloud services, giving administrators real-time insight into runtime, battery health, and load levels from virtually anywhere. That visibility enables proactive maintenance and helps prevent unexpected downtime.

Edge data centers, branch offices, network closets, and audio-visual racks all benefit from this combination of high power density and minimal space consumption. An eight-foot power cord and the included sliding rail kit simplify installation, whether you mount the unit in a shallow rack or set it on a shelf beside sensitive lab equipment.

A five-year warranty that covers both the electronics and the Lithium-ion battery keeps long-term ownership costs predictable while providing confidence that critical systems remain protected.
