Smart-UPS Ultra 3000VA 1U Rack/Tower

This APC Smart-UPS Ultra provides 3000VA and 2880W of on-line double-conversion power in a 1U rack-mountable or tower form factor. It delivers clean 120V output through five NEMA 5-20R receptacles and one NEMA L5-30R receptacle. Lithium-ion batteries enable extended runtime and a longer service life than traditional lead-acid designs. Network management is supported via the included network card and USB connection.

On-line topology lithium-ion thermal profile

The on-line architecture continuously conditions incoming power, isolating connected equipment from surges, sags and frequency variation. Lithium-ion cells generate less heat and accept charge more efficiently than lead-acid alternatives, reducing cooling demand in the rack. Fan speed adapts to load and temperature, keeping acoustic output low during typical operation. The 1U height preserves vertical space for additional hardware.

Replaces lead-acid 3000VA units when weight

This unit upgrades from heavier lead-acid UPS models of the same 3000VA rating where rack density, service intervals or extended runtime are priorities. The lithium-ion pack supports more discharge cycles and a longer calendar life, lowering total cost of ownership. The jump is worth it when reduced weight eases installation, when longer battery replacement intervals cut maintenance windows, or when the 1U footprint frees rack units for compute gear.

Questions about this item

How do I mount the 1U rack unit and attach the rail kit so the rear NEMA 5-20R and L5-30R outlets stay accessible?

Fasten the included rack mounting brackets to the chassis, slide the supplied support rails into the cabinet, then secure the unit with the front screws; the rear outlets face backward for cable routing.

When will the internal lithium-ion battery need replacement under normal operation?

The lithium-ion cells are rated for extended runtime and typically last the full service life of the UPS without a user-replaceable cartridge.

What load level triggers the first thermal or runtime limit during continuous use?

Drawing the full 2880 W / 3000 VA rating will exhaust the on-battery runtime first; sustained loads near that level also increase internal temperature.
