Onduleur Eaton 9SX

The Eaton 9SX is a 1 kVA double-conversion (online) uninterruptible power supply (UPS) that delivers continuous, regulated power for rack-mounted IT equipment. With a 900 W output power capacity and a 2U rack form factor, the unit provides sustained protection against power disturbances, voltage fluctuations and short interruptions. The model includes seven AC outlets with a mix of C13 and C14 couplers and a USB 2.0 port for basic communications. Certified to IEC/EN 62040-2 and other safety standards, this UPS is engineered for small to medium data centres, network closets and critical infrastructure where predictable power quality and compact rack integration are required.

Advantages

The Eaton 9SX uses online double-conversion topology to isolate connected devices from input mains variations and provide a stable sine-wave output. Its compact 2U rack design conserves rack space while supporting redundant power layouts and hot aisle deployments. Integrated monitoring via a USB 2.0 port enables safe shutdown and event logging through compatible management software. Built with recognized safety certifications, the unit offers reliable overload and short-circuit protection and is suitable for continuous operation in controlled environments.

Suitable for

• Rack-mounted servers and blade servers in small and medium data centres

How to use

Install the Eaton 9SX into a standard 19-inch equipment rack occupying 2U of vertical space. Connect the UPS input to a stable mains source using appropriately rated cabling and ensure the rack and room provide adequate ventilation and ambient temperature within the manufacturer’s recommended range. Plug protected devices into the provided AC outlets, prioritising critical equipment for the battery-backed outlets. Use the USB 2.0 port to connect to a monitoring host for graceful shutdown configuration and event logging. Test the UPS after installation to verify correct transfer to battery operation and confirm connected equipment remains powered during simulated mains interruptions.

Recommendations

Place the UPS in a controlled environment free from excessive dust, moisture and heat. Maintain regular battery checks and replace batteries according to the service schedule or when runtime significantly decreases. Avoid overloading the UPS beyond its 900 W continuous output rating; distribute loads across outlets and consider using additional UPS units or higher-capacity models for redundancy or greater power requirements.
