Frequently Asked Questions
What is a double-conversion UPS and why does it matter?
A double-conversion UPS, like the Eaton 9155, converts incoming AC power to DC, then back to AC. This process ensures your equipment always receives clean, regulated power free from electrical noise, surges, and frequency variations — critical for sensitive IT infrastructure and industrial systems.
How long will the Eaton 9155 keep my systems running during a power outage?
Runtime depends on your battery configuration and connected load. The 9155's scalable battery modules allow you to customize backup duration from minutes to hours, ensuring your critical systems have adequate time to shut down gracefully or transfer to backup power sources.
Is the Eaton 9155 suitable for data center applications?
Yes. The 9155 series is specifically designed for enterprise environments including data centers, offering high reliability, efficient operation, advanced monitoring capabilities, and the capacity to protect multiple servers and networking equipment simultaneously.
Can I upgrade or replace batteries without shutting down the UPS?
Yes. The Eaton 9155 features hot-swappable battery modules, allowing you to perform maintenance and battery replacements without interrupting power to your connected equipment — a critical advantage for 24/7 operations.
