Keep critical systems online with the APC Smart-UPS X 3 kVA, built for infrastructure that cannot afford unstable power. Its line-interactive topology helps condition incoming power while supporting fast response to disturbances, making it well suited for server rooms, edge deployments, and branch infrastructure where clean power and runtime both matter.
The 2U rack/tower convertible design gives teams flexibility during deployment, while the extended runtime configuration supports longer protection windows when outages outlast the usual assumptions. With a 100 V-127 V input range and a mixed outlet set that includes 3x 5-15R, 3x 5-20R, and 1x L5-30R NEMA receptacle, this unit can serve a range of IT loads without forcing adapter-heavy workarounds.
A network management card is included, giving operations teams the visibility and control expected in managed environments. The 10 ft input cord simplifies placement in dense racks. For organizations that value uptime, remote monitoring, and a proven UPS platform, this model earns its place by protecting more than just power — it protects continuity.
