Frequently Asked Questions
What is a three-phase UPS and why do I need one?
A three-phase UPS like the EXSV-20KN distributes power across three electrical phases, providing balanced load handling and superior efficiency for large-scale IT infrastructure. Three-phase systems are essential for data centers and industrial facilities requiring 20kVA or higher power protection, as they deliver more stable voltage regulation and reduce strain on individual circuits compared to single-phase alternatives.
How does double-conversion technology protect my equipment?
Double-conversion power protection continuously converts incoming AC power to DC, then back to AC, ensuring your critical loads receive perfectly conditioned power free from utility fluctuations, surges, and sags. The Liebert EXS EXSV-20KN's double-conversion design maintains 94% efficiency while delivering uncompromising protection for servers, networking equipment, and sensitive electronics.
Can the EXSV-20KN be expanded or configured differently?
Yes. The EXSV-20KN is built on a 40kVA frame, providing flexible configuration options and room for future expansion. This modular approach allows you to scale your power protection infrastructure as your facility grows, making it a cost-effective long-term investment for evolving data center and industrial environments.
What efficiency benefits does ECO mode provide?
ECO mode operation on the Liebert EXS achieves up to 99% efficiency by bypassing the inverter during normal utility conditions, significantly reducing energy consumption and operational costs. This feature is ideal for facilities seeking to lower their power footprint while maintaining reliable backup protection for critical systems.
