Eaton 9SX 2000VA 1800W 208V Online Double-Conversion UPS — 8 C13 Outlets

Choose power you can trust for every critical device in your data center, small server room, or high-demand office environment. The Eaton 9SX 2000VA 208V Online Double-Conversion UPS delivers pristine, uninterrupted power with a robust feature set designed to protect servers, storage appliances, network gear, and workstations from outages, surges, and damaging waveform irregularities. Built around a true online, double-conversion topology, this UPS continuously converts incoming AC to DC and back to a regulated sine wave, ensuring clean voltage regardless of input fluctuations. It’s the ideal backbone for applications where data integrity and uptime are non-negotiable, offering rated capacity of up to 1800 watts to support demanding workloads while maintaining a compact tower footprint that fits neatly in data rooms, telecom closets, or office spaces. The 9SX is designed to work seamlessly with 208V power infrastructure, delivering stable performance in environments that rely on high-efficiency, scalable power for servers, virtualization hosts, NAS devices, switches, and essential networking equipment. From immediate surge suppression and AVR (automatic voltage regulation) to intelligent battery management and remote monitoring capabilities, the Eaton 9SX delivers reliability you can count on during both routine operations and unexpected power events.

• Online double-conversion protection for a perfect output waveform: even during mains disturbances, the UPS continuously regenerates clean, regulated AC power to protect sensitive equipment and prevent data loss.
• 208V compatibility with 8 IEC C13 outlets: power multiple devices—servers, storage, switches, and workstations—from a single, organized UPS with room to expand as your infrastructure grows.
• Cybersecure Network Card Option for secure remote management: monitor voltage, battery health, and runtime from anywhere with encrypted access and role-based permissions.
• Extended Run capability with scalable battery options: add battery modules to extend runtime for longer outages without interrupting critical workloads.
• Tower form factor with practical access: compact footprint, front-access battery compartments, and straightforward deployment in typical office or data-center spaces.

How to install Eaton 9SX 2000VA 208V UPS

Begin with a suitable installation site. Choose a dry, well-ventilated space that’s free from excessive heat, moisture, and dust. Leave enough clearance around the unit for airflow and service access, and place the UPS in a stable position on the floor in a dedicated area of your server room or office closet. If you plan to mount the unit on a desk or shelf, ensure the surface can support the weight of the UPS plus connected loads.

Position the UPS in Tower orientation, with the front panel readily accessible. If you anticipate rack installation, confirm whether any optional mounting accessories are needed for your rack configuration and ensure the 208V input cord has the proper length to reach the power source without tension.

Connect the UPS to the main power supply. Use the appropriate 208V circuit capable of handling the anticipated load. It’s best practice to deploy a dedicated circuit for the UPS to minimize interference from other equipment and to ensure stable operation under peak demand.

Attach the devices you want to protect to the 8 IEC C13 outlets. Distribute critical payloads—such as servers, network switches, and storage devices—across multiple outlets to reduce the risk of a single point of failure. Do not exceed the rated load (1800 W) to preserve runtime and protect the UPS from overheating or nuisance trips during power events.

If you plan to use the Cybersecure Network Card Option, install the card per the user guide and connect the UPS to your network. Configure secure user accounts, enable remote monitoring, set up alerts, and ensure firewall rules permit proper communication with the monitoring software. If you don’t require remote management immediately, you can deploy the card later as your infrastructure expands.

Install the battery modules or verify existing modules are properly seated. For Extended Run scenarios, ensure battery modules are compatible with the Eaton 9SX unit and follow the vendor’s guidelines for connecting and configuring modules. Allow the UPS to charge for a few hours after initial installation before placing the protected equipment into full production. This initial charge helps maximize runtime accuracy and battery health while the UPS stabilizes its internal conditioning.

Power up the UPS and perform a self-test from the management interface or manual switch sequence. This step verifies the integrity of the battery system, the 208V output, and overall functionality. Record the results and address any warnings or errors as indicated by the display indicators or monitoring software. Create a baseline configuration that matches your equipment load and desired alert thresholds for voltage, battery health, and run time.

Finally, implement a monitoring strategy. Use the optional Cybersecure Network Card to enable remote monitoring, or install the corresponding software on a central server to track runtime, input voltage, and battery status. Regularly review reports, test battery capacity, and plan periodic maintenance or battery replacements to ensure the UPS continues to deliver reliable protection during demand spikes or outages.

Frequently asked questions

• What is the Eaton 9SX 2000VA 208V UPS best used for? It is ideal for protecting servers, network devices, storage systems, and critical IT equipment in small to mid-sized data centers, server rooms, or office environments where 208V power is standard and uptime is essential.
