APC Smart-UPS 450VA 230V 1U Rackmount/Tower Uninterruptible Power Supply

The APC SC450RMI1U is an uninterruptible power supply that provides 450 volt ampere, or 280 watts, of reliable output to keep essential equipment running when utility power falters. It gives small and medium businesses a straightforward way to safeguard entry-level servers, switches, and other network gear from sudden outages, surges, and electrical noise.

Automatic voltage regulation inside the unit stabilizes incoming power, and built-in surge suppression filters out spikes before they reach your devices. Four IEC 60320 C13 outlets handle common IT loads, while RJ-11 and RJ-45 connectors protect phone or data lines, reducing the risk of equipment damage during storms or wiring faults.

Installation is flexible. You can slide the chassis into a standard 19-inch rack where it occupies just 1U of space, or stand it upright as a tower when rack space is unavailable. Weighing only 22.4 pounds, the UPS is light enough for one person to carry and mount. All serviceable parts sit behind a front panel, so routine maintenance or a battery swap never requires you to disconnect cables or pull the unit out of the rack.

During an outage the sealed lead-acid battery delivers up to 5.9 minutes of backup at the full 280 watt load, and roughly 19.4 minutes at half load. That window lets you save work, perform a graceful shutdown, or bridge the gap until a generator takes over. The battery is hot swappable, and intelligent charging algorithms help prolong battery life, lowering long-term operating costs.

The SC450RMI1U fits neatly into branch offices, retail back rooms, medical clinics, or home labs where reliable power is critical but space is limited. Network administrators, point-of-sale managers, and technically minded home users alike will appreciate the confidence that comes from knowing a blackout will not interrupt business.
