The Xtreme Power Conversion P91-1500 and Eaton 9PX1500RT are true online, double-conversion UPS systems designed to protect critical IT, network, AV, and edge infrastructure. Both deliver continuous sine-wave output and enterprise-grade protection from power disturbances.
However, the P91-1500 differentiates itself with higher usable output power, significantly faster recharge time, greater runtime scalability, lighter weight, and full TAA compliance, making it especially well suited for long-runtime installations, space-constrained racks, and U.S. government or public-sector environments.

Where the P91-1500 Excels

  • Long-runtime installations requiring fast recharge and scalable batteries
  • Edge, IDF, and MDF deployments with limited rack depth
  • Federally funded and TAA-restricted procurement environments
  • Sites operating at higher elevations or warmer ambient conditions
  • Installations prioritizing lower total cost of ownership

When Eaton 9PX1500RT May Be a Fit

  • Existing Eaton-standardized UPS environments
  • Applications with modest runtime requirements
  • Projects where TAA compliance is not required

Who Should Choose Which

Choose Xtreme Power Conversion P91-1500 if you need:
