APC SMX750I 750VA Line-Interactive Tower UPS
Overview
The APC SMX750I is a standalone tower uninterruptible power supply designed to provide battery-backed power protection and voltage regulation for small IT systems and network equipment. It is typically deployed by IT administrators and infrastructure technicians to safeguard standalone servers, workstations, switches, routers, and other rack or desktop electronics against power outages, voltage sags, surges, and electrical noise. The UPS maintains stable AC output during utility disturbances and provides sufficient runtime to perform controlled shutdowns during extended power loss events.
This system delivers 750VA / 450W output capacity using a line-interactive architecture with pure sine wave output. Automatic Voltage Regulation (AVR) corrects high and low voltage conditions without switching to battery operation, helping to extend the life of the battery during normal power fluctuations. The UPS operates in 120V power environments and connects to facility power via a standard NEMA 5-15P input. Power is provided to connected equipment through a set of six NEMA 5-15R battery-backed outlets.
The unit is engineered as a compact tower form factor to accommodate environments where rack installation is unnecessary or impractical. Typical installation locations include small IT closets, network edge cabinets, home labs, retail point-of-sale racks, or office infrastructure closets. The tower design allows flexible placement near equipment requiring power protection without consuming cabinet rack units.
Operational visibility is provided through an LCD interface displaying real-time status of load levels, battery condition, and input/output power parameters. The UPS also includes USB communication support for integration with server or workstation shutdown software, enabling coordinated shutdown procedures when utility power is unavailable. This functionality assists in minimizing data loss and equipment damage during outages.
This UPS is not intended for high-density server racks or environments demanding multi-kilowatt power protection. Deployments requiring larger capacity, extended runtime, or rackmount form factor UPS systems are better served by higher-rated models.
