APC SMT3000R2X145 – 3 kVA Line‑Interactive UPS

Overview :

The APC SMT3000R2X145 is a 3 kVA (2880 VA / 2700 W) line‑interactive rackmount UPS designed to provide regulated AC power and battery backup for critical IT systems. It is typically deployed by infrastructure engineers and operations teams to protect servers, network equipment, and storage from outages, sags, and surges in commercial and enterprise environments.

This UPS uses line‑interactive topology with Automatic Voltage Regulation (AVR) to correct under‑ and over‑voltages without unnecessary battery discharge, improving battery life and load stability. It delivers a pure sine‑wave output at 120 V, ensuring compatibility with sensitive electronics and active PFC power supplies.

The unit’s 2U rackmount form factor with included mounting hardware allows installation in 19‑inch server racks and network closets where space efficiency and clean rack integration are required. An intuitive LCD status display provides real‑time information on load, battery level, and utility conditions.

Management and control interfaces include USB and serial ports plus a modular SmartSlot expansion, enabling remote monitoring, event logging, and orderly shutdowns with compatible software. Hot‑swappable battery capability reduces downtime during replacement operations.

In practical deployment, this UPS is suited for power protection in small to mid‑size server racks, virtualization hosts, core networking gear, and storage arrays. It should not be selected for environments demanding fully online double‑conversion UPS protection with zero transfer time.
