Frequently Asked Questions
What is a three-phase UPS and why do I need one?
A three-phase UPS like the Liebert EXS20KN is designed for larger commercial and industrial applications requiring balanced power distribution across three electrical phases. This configuration provides superior power quality, efficiency, and scalability compared to single-phase systems, making it ideal for data centers and critical infrastructure where downtime is not an option.
What does the IS-UNITY-DP network communication card do?
The IS-UNITY-DP network communication card enables remote monitoring, management, and alerting capabilities for your UPS system. This allows IT teams to track power status, battery health, and system performance from anywhere, facilitating proactive maintenance and rapid response to potential issues.
How long will the internal VRLA battery provide backup power?
The internal VRLA battery provides backup runtime that varies based on load conditions. At full 20kW load, runtime is typically shorter; at reduced loads, the system can sustain operations longer. Consult the detailed specifications or contact our team for precise runtime calculations based on your specific power requirements.
Is the Liebert EXS20KN suitable for my data center?
Yes, the Liebert EXS 20kVA UPS is purpose-built for data centers and IT infrastructure. Its compact design, high-power-density footprint, on-line topology, and integrated network communication make it an excellent choice for organizations seeking reliable, economical power protection without sacrificing performance or space.
