Eaton 9SX 1000VA 900W 120V Online Double-Conversion UPS - 6 NEMA 5-15R Outlets, Cybersecure Network Card Option, Extended Run, Tower

Protect your most important IT equipment with a compact, scalable power protection solution designed for reliability in demanding environments. The Eaton 9SX 1000VA 900W 120V Online Double-Conversion UPS delivers pristine, uninterrupted power for servers, networking gear, workstations, and small-scale storage devices. Built around true online double-conversion technology, this tower UPS continuously converts incoming AC power to DC and then reconverts it back to a clean, regulated sine-wave AC output. The result is a steady power source that shields equipment from voltage sags, surges, outages, and harmonic distortion, reducing the risk of data loss and hardware damage during power disturbances. Ideal for small data centers, IT closets, home offices with critical workloads, and professional environments where uptime matters, the 9SX blends Eaton reliability with a compact footprint and straightforward management options. With six NEMA 5-15R outlets, optional cybersecure network card, and support for extended runtime, it provides a flexible foundation for protecting essential devices while maintaining energy efficiency and serviceability. Whether you’re safeguarding a rack of servers, a core switch, NAS devices, or desktop workstations, the Eaton 9SX is engineered to keep your systems online and your data safe, even when the grid falters.

• True online double-conversion protection for clean, continuous power: The 9SX uses a continuous power conversion cycle to deliver an uncompromised, regulated sine wave output. By retransforming DC back to AC in real time, it eliminates input voltage fluctuations, keeps connected equipment within safe voltage bands, and minimizes the risk of data corruption during surges, sags, or outages. This technology is especially valuable for sensitive servers, network gear, and storage devices that demand stable power irrespective of the condition of the incoming supply.
• Six NEMA 5-15R outlets for comprehensive device protection: Six standard 120 V outlets provide abundant, versatile ports for critical components such as servers, routers, switches, storage arrays, workstations, and backup devices. The layout enables you to prioritize essential equipment on the UPS while keeping non-critical peripherals protected, simplifying cable management and reducing the need for additional power strips in crowded IT spaces.
• Optional Cybersecure Network Card for secure remote management: In professional IT ecosystems, secure monitoring and graceful shutdowns are essential. The opted Cybersecure Network Card option enables secure, centralized remote management of the UPS, allowing IT staff to monitor runtime, perform controlled shutdowns, and receive alerts without compromising network security or requiring direct on-site access. This feature integrates with enterprise management workflows to support proactive risk mitigation.
• Extended Run and scalable runtime options: The 9SX is designed to grow with evolving needs. When longer uptime is required, the UPS supports extended runtime configurations through external battery modules, enabling you to extend backup time for mission-critical workloads. This capability is ideal for small data centers, lab environments, or edge deployments where maintaining data integrity and orderly shutdowns is essential during extended outages.
• Tower design with easy maintenance and visibility: The upright, compact tower form factor fits neatly under desks or in small server rooms, optimizing space and airflow. Front-panel indicators and an intuitive LCD or LED status display provide quick visibility into load, battery level, and fault conditions, while accessible battery modules and serviceable components reduce maintenance downtime and simplify field service.

How to install Eaton 9SX 1000VA 900W 120V Online Double-Conversion UPS

• Choose a stable, well-ventilated mounting location. Place the UPS on a solid surface with clear space around it to allow airflow and access to outlets and the front panel.
• Connect the UPS to a grounded 120 V AC wall outlet. Avoid using extension cords or power strips for the input connection to ensure proper protection and performance.
• Plan load placement: connect critical devices (servers, network gear, NAS) to the 6 NEMA 5-15R outlets. Reserve non-critical peripherals on remaining outlets to optimize uptime for essential equipment.
• Power up and configure: turn on the UPS and verify the front-panel indicators or LCD display. If you have the Cybersecure Network Card option, install and configure it according to the manual to enable secure remote monitoring and management.
• Extend runtime if needed: assess your load and consider attaching external battery modules to achieve your target uptime during outages. Calibrate runtime expectations based on the actual load using the UPS software or management interface.

Frequently asked questions

• Q: What is online double-conversion and why is it important? A: Online double-conversion continuously converts incoming AC power to DC and then back to a clean, regulated AC output. This topology delivers near-ideal power quality regardless of input fluctuations, which reduces the risk of data loss, hardware stress, and unexpected shutdowns for sensitive equipment.
• Q: How many devices can I protect with six outlets? A: The 6 x NEMA 5-15R outlets provide substantial capacity for a mix of servers, networking gear, and workstations. This setup is ideal for small to mid-size deployments where critical devices require reliable backup power and surge protection.
• Q: Is the Cybersecure Network Card available for this UPS? A: Yes, there is an optional Cybersecure Network Card that enables secure remote monitoring and management of the UPS, integrating with enterprise monitoring solutions while maintaining network security.
• Q: Can runtime be extended? A: Yes. The Eaton 9SX supports extended runtime configurations through external battery modules, allowing longer autonomous operation for essential systems during outages.
• Q: What kind of environments is the 9SX best suited for? A: It is designed for small data centers, IT closets, edge deployments, and professional workstations where reliable, clean power and protection from disturbances are critical for maintaining uptime and data integrity.
