9SX5KI Eaton 5000VA Online (Double-Conversion) UPS/USV

High-Performance online double-conversion UPS power protection with the 9SX5KI for critical single-phase loads

The 9SX5KI is an Eaton 9SX Series online double-conversion tower UPS engineered to isolate sensitive IT and networking equipment from utility disturbances while maintaining continuous operation under single-phase infrastructure. By converting incoming AC to DC and regenerating a clean sinewave output, the 9SX5KI delivers consistent power quality for rack servers, storage, and network aggregation in server rooms, edge sites, and branch environments.

Architecturally, the 9SX5KI is designed for stable capacity delivery at 5000VA/4500W with hardwired single input feed integration, enabling predictable upstream breaker planning and simplified electrical design. The online topology supports clean power conditioning to protect power supplies and downstream conversion stages, while the tower form factor suits small-row deployments where floor space, access, and serviceability matter. Compliance to IEC/EN 62040-1/-2/-3, UL 1778, FCC Part 15 Class A, and CB aligns the 9SX5KI with enterprise safety and EMC expectations for mixed IT and building environments.

Why Choose the 9SX5KI?

The 9SX5KI is selected when you need deterministic power continuity and conditioning in a compact, serviceable tower footprint without compromising enterprise reliability. For single-rack or small-row critical loads, the 9SX5KI provides a strong density-to-performance ratio, supports scalable edge/branch deployment patterns, and reduces operational risk by maintaining stable output during voltage events, frequency variation, and outages.

Eaton designs the 9SX platform with an emphasis on electrical robustness, standards-based interoperability, and long-term maintainability, supporting modern data centre and edge practices where uptime, predictable behaviour, and compliance are mandatory.

Key Applications:

• Single-rack server room power protection
• Network core and security appliance continuity
• Edge and branch IT runtime support
• Storage and backup appliance protection
• Industrial IT and control-room power conditioning
