Frequently Asked Questions
What is a modular UPS and why choose the Eaton 9PXM?
A modular UPS uses interchangeable power modules to scale capacity on demand. The Eaton 9PXM's N+1 architecture allows you to add capacity from 4–20 kVA without shutting down operations, making it ideal for growing data centers and critical infrastructure requiring continuous uptime.
How does online double-conversion technology protect my equipment?
Online double-conversion continuously converts incoming AC power to DC, then back to clean AC output, eliminating voltage fluctuations, surges, and sags in real-time. This ensures sensitive servers, storage, and networking equipment operate at optimal performance with maximum protection against power anomalies.
Can the Eaton 9PXM UPS support different voltage inputs?
Yes. The 9PXM supports multiple voltage configurations including 110V/220V, 120V/208V, 120V/240V, and 127V/220V, making it suitable for diverse global installations and simplifying international data center deployments.
What are the space and installation benefits of the 21U rack/tower design?
The compact 21U form factor maximizes rack density in data centers while the free-standing enclosure option provides flexibility for non-racked installations. Hardwired input/output connections reduce cable clutter and improve reliability compared to connector-based systems.
