Eaton 9SX 3000i Rack2U Online UPS 3000VA 2700W, Rackmount

The 9SX 3000i uses online topology, the type of UPS that continuously powers the load through its own conversion stage instead of switching over only when mains power fails. Connected equipment receives steady, conditioned power whether the incoming supply is stable, fluctuating or absent. That makes this design a common choice for servers, storage arrays and network hardware, where even a brief interruption or a poor-quality supply can cause downtime or data loss.

With a rated capacity of 3000 VA and 2700 W, this UPS can support a substantial rack of equipment, such as several servers, switches, routers and storage devices. The high real-power rating gives you headroom for modern IT hardware. When planning your setup, add up the power draw of all connected devices and keep the total within the 2700 W rating to ensure reliable protection.

The unit contains an embedded rechargeable battery that takes over immediately when mains power drops out, giving you time to finish critical tasks or shut systems down safely. The manufacturer does not list the battery capacity or runtime figures in the specifications provided, so check Eaton's runtime data against your actual load when sizing the system for a specific backup period.

Built for rack installation, the 9SX 3000i Rack2U is designed to fit standard server cabinets alongside your other IT equipment, keeping cabling tidy and saving floor space. The black finish matches typical rack hardware. With a net weight of 26.50 kg, the unit should be installed on suitable rack rails or shelving, and lifting it into place is easier with two people.

This UPS carries a broad set of certifications: IEC/EN 62040-1 for UPS safety, IEC/EN 62040-2 for electromagnetic compatibility, UL 1778, cULus Listed, CE and EAC. These approvals confirm that the unit meets recognised requirements for safety and electromagnetic compatibility, which matters for businesses that need to show their infrastructure complies with established standards.

This online rackmount UPS suits IT administrators, small and medium businesses, server rooms, telecom installations and anyone running network or storage equipment in a rack. Thanks to its 2700 W capacity and conditioned output, it can protect mission-critical hardware that needs continuous, clean power rather than basic surge protection.
