Frequently Asked Questions
What is N+1 redundancy in a UPS frame?
N+1 redundancy means the 9PXM UPS frame includes one additional power module beyond the minimum required capacity. If one module fails, the remaining modules continue protecting your equipment without interruption, ensuring zero downtime for mission-critical applications.
How does online double-conversion technology protect my equipment?
The 9PXM double-conversion UPS continuously converts incoming AC power to DC, then back to clean AC output. This process isolates your equipment from power surges, sags, and noise while maintaining zero-transfer-time switching during outages—critical for servers and networking gear that cannot tolerate power interruptions.
Can the Eaton 9PXM UPS frame scale as my power needs grow?
Yes. The modular 12-slot frame design allows you to add or upgrade power modules to increase capacity from 4 kVA up to 20 kVA without replacing the entire system, protecting your infrastructure investment and reducing long-term costs.
What voltage options does the 9PXM support?
The 9PXM frame offers split-phase output in 110V/220V, 120V/208V, 120V/240V, and 127V/220V configurations, accommodating regional power standards across North America, Europe, and international deployments.
