Ultra-Compact 3000VA UPS

The APC Smart-UPS Ultra delivers 3000VA of lithium-ion battery backup in a 1U tower/rack convertible chassis. It provides 120 V AC input and output with automatic voltage regulation. This unit suits IT managers protecting dense server racks or edge equipment where rack space is at a premium.

Runtime and Load Constraints

The 3000VA rating sets the practical ceiling for connected gear; exceeding it will trip the unit or cut runtime short. Automatic voltage regulation handles sags and swells without draining the battery, but sustained overloads cannot be supported. Plan loads so the total draw stays within the rated capacity.

Connector Layout and Daily Use

The rear panel offers one NEMA L5-30R and five NEMA L5-20R outlets, all locking types that resist accidental disconnects. The 1U form factor fits standard racks yet converts to tower orientation for floor placement. Locking receptacles mean routine cable checks replace frequent reseating.
