Delivering unrivaled performance and reliability, this UPS is the perfect power solution for corporate and industrial applications – including telecom, healthcare, banking, retail, small data centers, and more. Ask about options for Lithium-Ion Battery Systems for the Eaton 9355 UPS System.


The Eaton 9355 UPS provides premium double-conversion backup power and scalable battery runtimes for IT and electrical engineering infrastructure in corporate, healthcare, banking and industrial applications. Packing maximum battery runtime into a very small footprint, the 9355 UPS is a complete three-phase power protection solution. The 9355 can be equipped with an integrated, customizable power distribution module that includes a maintenance bypass switch.

features and benefits


Sleek, Efficient Design

The 9355 offers the smallest footprint of any comparable UPS, with standard internal batteries, often eliminating the need for costly, space-consuming external battery cabinets. The 9355’s design doesn’t just look pretty, providing more real power in less space with a high 0.9 output power factor. In fact, this particular UPS offers industry-leading power density with up to a 75 percent smaller footprint and 13 percent more power capacity than comparable UPSs.

Scalability

Are you growing quickly? Up to FOUR 9355 UPSs can be paralleled to ensure your facility’s capacity is able to grow right along with you. Models can also be upgraded with additional capacity at your discretion. Moreover, Eaton’s built in Hot Sync® technology enables wireless paralleling, adding redundancy in case of communication failure to keep you as protected as possible.

On-board Power Distribution

Give your data center managers more flexibility with the 9355’s on-board power distribution module. Able to be configured for hardwired output or with a variety of output receptacles, they’ll be able to preserve valuable rack space and installation expenses.

Increased Intelligence for Premium Power Protection

The 9355 continually monitors incoming electrical power, working with a building’s existing electrical system to supply clean, consistent power, and avoid incoming electrical anomalies. Constantly monitoring its own operation, correcting any problems on the fly, or sending an alarm to act, the 9355 keeps you protected from the majority of issues common with commercial utilities. Advanced battery management is also designed to maximize battery health and service life. 


Regardless of your chosen configuration, you can expect the 9355 to deliver improved runtimes and significantly reduced footprints over any other competitor.

Runtime Solutions

In the event of an outage, two options exist to continue providing power to the UPS load: lithium-ion batteries and a flywheel system. While more expensive than lithium-ion batteries, flywheel systems offer many benefits, including:


  • limited required maintenance
  • 20-year design life
  • the ability to operate in high temperature environments
  • and 90% reduced carbon footprint when compared to batteries

Lithium-Ion Battery

  • Lithium Ion battery packages not available in 9355, but available in other select models
  • Lithium Ion battery system for Eaton UPS Systems provides low maintenance, long life battery system of the future.
  • Minimal maintenance, highly reliable, smaller footprint, long life, slightly higher up front cost
