Frequently Asked Questions
What is N+1 redundancy in a modular UPS system?
N+1 redundancy means you have one additional UPS module beyond what's needed to handle your load. If one module fails, the remaining modules continue protecting your equipment without interruption. The Eaton 9PXM's modular architecture supports this configuration, allowing you to scale from 4 kVA to 20 kVA while maintaining fault tolerance.
Can I expand the Eaton 9PXM UPS capacity without replacing the frame?
Yes. The modular scalable design of the 9PXM allows you to add power modules within the same 21U cabinet, scaling capacity from 4 kVA up to 20 kVA. This eliminates costly infrastructure replacement and simplifies future growth.
What voltage options does the 9PXM support?
The Eaton 9PXM UPS frame supports multiple split-phase voltage configurations: 110V/220V, 120V/208V, 120V/240V, and 127V/220V. This flexibility ensures compatibility with diverse global power standards and facility requirements.
Is the 9PXM suitable for data center and server room applications?
Absolutely. With online double-conversion technology, hardwired connections, N+1 redundancy support, and a professional 21U rack/tower design, the Eaton 9PXM is purpose-built for mission-critical environments where continuous power and high availability are non-negotiable.
