Eaton 9SX1000 – Online UPS 1 kVA 900 W Tower
Overview
The Eaton 9SX1000 is an on‑line double‑conversion uninterruptible power supply (UPS) intended for IT power continuity and protection where regulated AC output and zero transfer time to battery are required. It’s used by data center engineers, network infrastructure teams, and facilities operators to safeguard critical servers, switches, storage, or edge appliances against outages, voltage sag/surge, and frequency variation in single‑phase 120 V environments.
Electrically, the UPS is rated at 1000 VA / 900 W output with true sine wave output and a 0.9 power factor, enabling efficient support of active‑PFC loads typical in modern IT equipment. It includes six NEMA 5‑15R receptacles on the rear panel and supports external battery expansion modules (EBMs) for extended runtime.
Physically configured in a compact tower form factor (~9.9 in high × 6.3 in wide × 15.1 in deep) and weighing around 30.9 lb (14.0 kg), the 9SX1000 is suitable for placement on a rack shelf, under a desk, or adjacent to a network cabinet in wiring closets, branch offices, or small enterprise data rooms.
The UPS integrates multi‑protocol communication including USB, RS‑232 serial, and a Mini‑Slot expansion port for optional network connectivity cards (Web/SNMP or Modbus) to connect with management platforms such as Eaton Intelligent Power Manager (IPM) for shutdown automation and telemetry.
In a typical deployment, the 9SX1000 supports clean, uninterrupted power for a small rack segment — for example, a cluster of edge switches and routers in a branch wiring closet — while providing runtime buffering to perform orderly shutdowns when utility power fails. It is not suitable for larger three‑phase central power distribution environments or for loads exceeding its 900 W capacity.
