Frequently Asked Questions
What is a 12kVA UPS and why do I need one?
A 12kVA UPS (uninterruptible power supply) provides immediate backup power during electrical outages, protecting critical IT equipment from data loss and downtime. The Eaton 9155 is ideal for data centers and enterprise environments where continuous power is essential for business operations.
What's the difference between 5-20R, 6-15R, and 6-20R receptacles?
These are standard North American outlet types with different voltage and amperage ratings. The Eaton 9155 includes all three types (4 of each), allowing you to connect equipment with varying power requirements—from standard office devices to high-current server equipment—without additional adapters.
How does double-conversion technology improve power quality?
Double-conversion UPS systems convert incoming AC power to DC, then back to clean AC power, filtering out voltage spikes, sags, and electrical noise. This ensures your servers and networking equipment receive perfectly conditioned power, reducing hardware failures and extending equipment lifespan.
Is the Eaton 9155 suitable for small business data centers?
Yes. With 12kVA capacity and flexible outlet configuration, the Eaton 9155 is well-suited for small to mid-sized data centers, server rooms, and enterprise IT closets requiring scalable, reliable backup power protection for multiple device types.
