Product Description
Key Features & Benefits
-
True Online Double-Conversion: Ensures the load is always isolated from utility power anomalies, delivering a consistent, clean sine wave.
-
Internal Battery Capability: Houses internal batteries providing approximately 8–9 minutes of runtime at full load, with the option to add external “Line and Match” cabinets for extended runtime.
-
Ultra-Quiet Performance: At less than 54 dBA, it is significantly quieter than most industrial UPS units, making it ideal for healthcare and professional environments.
-
Intelligent Paralleling: Up to four NXb modules can be paralleled for increased capacity or N+1 redundancy without the need for a centralized controller.
-
Generator Friendly: Low input current distortion (THDi < 4%) and high input power factor ensure the unit works seamlessly with backup generators without requiring significant oversizing.
-
Advanced Monitoring: Features a large user-friendly LCD display and is compatible with Liebert’s IntelliSlot™ cards for remote web/SNMP management.
