ENERGY STAR® qualified and ideal for both rack-mount and stand-alone installations, the EATON 9PX UPS delivers premium backup power and scalable battery runtimes for servers, voice/data networks, and storage systems. Ergonomically-designed and intuitive graphical LCD interface and robust power management software simplifies managing your industrial UPS system or commercial UPS system— even in virtualized environments.

Features & Benefits

  • Enables you to customize UPS settings, view load and power consumption information through the graphical interactive LCD interface.
  • Fully integrates with Intelligent Power Software Suite for continuous up time of servers and virtual machines.
  • Provides more real power (watts) to protect more equipment and leave room for expanding IT systems.
  • Delivers added runtime with extended battery modules and extends battery service life by 50% with ABM technology.
  • Cuts energy usage and costs with ≥93% efficiency rating in normal mode
  • Maximizes availability with extended battery runtime options, hot-swappable batteries, internal bypass and optional maintenance bypass.
  • Helps save money and protect the environment through energy efficient operation (ENERGY STAR® qualified UPS).
  • Split-phase models offer both 120V and 208V output without a transformer; saving vertical rack (U) space, weight and cost.
