Reliability and efficiency have never looked so attractive. The 9155 single-phase Uninterruptible Power System (UPS) delivers a combination of advanced technology, userfriendly design and low price that's absolutely unmatched by competing products. This innovative design offers high efficiency (90 percent or better across all load ranges), low input current distortion (less than 5 percent total harmonic distortion, with an active IGBT rectifier that delivers 0.99 power factor correction) and high power factor output (0.9 PF).

With advances being made in miniaturization and processing power and more equipment being served by dual-cord power supplies, the challenge of protecting that power, and doing so in a limited space, grows ever greater.

Fortunately, advances in technology have also meant that more power protection per square foot can now be provided. The 9155 delivers premium levels of efficiency, reliability and flexibility, all in a sleek tower half the size of most other units on the market today.


  • A true online, double-conversion topology protects connected equipment from all nine of the most common power problems
  • Delivers maximum power density in a compact tower design: 12" wide and 33" deep, including batteries
  • Provides more real power in less space (5,500 watts per square foot) with a 0.9 output power factor – protecting more equipment for every utility dollar and leaving more room for expansion of the data center
  • Patented Powerware Hot Sync® paralleling of multiple modules delivers extra capacity or redundancy
  • Customizable output distribution provides user-specified power outlets along with terminals for connecting hardwired equipment
  • Microprocessor-controlled ABM® technology significantly increases battery life
  • Provides a 0.99 input power factor and generator friendly 5% total harmonic distortion using an active IGBT rectifier to control the input power factor
  • Ensures data and system integrity with complete power management software for remote monitoring, management and shutdown
  • An Eaton factory limited warranty, technical support and optional service plans provide investment protection and peace of mind

Premium power protection is now easier than ever.

With raised-floor real estate at a premium, you'll appreciate that the 9155 requires only three to six square feet of floor space, including internal batteries. Such a small footprint gives you more location options and more space available for future expansion.

Equipment installation is inexpensive and easy – essentially plug-and-play. You can order 9155 models with your choice of more than 19 types of output receptacles. To rearrange or add data center equipment, you simply unplug from the old receptacle and plug into a new one – no need for an electrician to run new conduit and wiring.

Scalable architecture meets current and future load requirements.

9155 UPSs are available in four models: 8, 10, 12 and 15 kVA, so you can choose the configuration that most closely meets your own capacity requirements and price point. And you can scale from there. Using our signature Hot Sync paralleling technology, up to three 9155 modules can be paralleled for extra capacity or redundancy. A 15 kVA UPS, for example, can grow to support loads of up to 45 kVA. There's no dependence on communications wiring among these modules, enhancing reliability and simplifying installation. This paralleling capability Is far more easily achieved than is the case with competitors' products.

Battery innovations optimize battery performance and service life.

Standard internal batteries provide power until auxiliary power takes over or systems are gracefully shut down. Battery runtime can be extended to hours by adding matching Extended Battery Modules (EBM).
