Frequently Asked Questions
What is the difference between a 10kVA UPS and a 10kW UPS?
The Liebert EXS 10kVA UPS delivers 10,000 volt-amperes of apparent power. With a unity power factor output, this translates to 9kW of real power. The distinction matters for sizing: kVA accounts for reactive power, while kW measures actual usable power. For most IT equipment, the 10kVA capacity provides ample protection for servers, networking hardware, and critical infrastructure.
Why choose double-conversion UPS technology?
Double-conversion technology in the Liebert EXS ensures your equipment receives continuously conditioned, clean power. Unlike standby UPS systems, double-conversion provides zero transfer time to battery during power events, eliminating any risk of equipment disruption. This makes it ideal for mission-critical applications where downtime is not an option.
How does ECO mode improve efficiency on this 208/220V UPS?
ECO mode on the Liebert EXS 10kVA reduces energy consumption by allowing the UPS to operate in a more efficient state during normal conditions. By achieving up to 99% efficiency in ECO mode, you lower operational costs and heat generation in your data center or server room, while maintaining full battery backup protection when needed.
Is the Liebert EXS 10kVA suitable for small server rooms?
Yes. The compact tower design of the Liebert EXS 10kVA makes it an excellent fit for space-constrained environments. Its monolithic integrated design requires minimal floor space while delivering robust 10kVA power protection, making it ideal for small to mid-sized server rooms, network closets, and branch office installations.
