Frequently Asked Questions
What is a double conversion UPS and why does it matter?
A double conversion UPS continuously converts incoming AC power to DC, then back to AC, ensuring the output is always clean and stable. This topology provides superior protection against power anomalies, voltage spikes, and frequency variations — critical for sensitive server equipment and data center infrastructure.
How long will the Eaton 9355 keep my equipment running during a power outage?
Runtime depends on your connected load. At full 10KVA capacity, expect approximately 5-10 minutes of backup power. The 64 lead-acid battery pack with 9 Ah capacity is designed to bridge short outages and allow graceful system shutdown or failover to alternative power sources.
Is the Eaton 9355 suitable for data center applications?
Yes. The 10KVA tower UPS is specifically designed for enterprise data centers, server rooms, and mission-critical environments. Its double conversion technology, hot-swap battery capability, and network management compatibility make it ideal for high-availability deployments requiring continuous power protection.
Can I monitor the Eaton 9355 remotely?
Yes. The UPS supports optional network management cards that enable remote monitoring, alerting, and control via Ethernet. This allows IT teams to track power status, battery health, and load levels from anywhere on the network.
