New Technology For A New Level Of Performance
With over four decades of the most reliable UPS systems, and the industry’s most experienced engineering resources, Vertiv™ has delivered the Liebert® NXL™ UPS—the latest generation of high availability, high performance UPS for critical data center equipment.
- Employs the latest generation insulated gate bipolar transistors (IGBTs) and advanced inverter logic with active harmonic control for enhanced performance under a wide range of power conditions.
- Provides high efficiency, up to 94%, but more importantly, the efficiency is optimized with a very flat efficiency curve that peaks at about 50% load where most UPS systems, especially redundant UPS systems, are operating. This results in significant savings on the energy bill.
- Digital control technology provides precise, drift-free regulation of system operation.
- Supports leading power factor loads up to 0.95 without derating, addressing the power needs of current and future generations of computers.
Higher Availability
- 100% rated continuous duty bypass static switch—unfused.
- Superior handling of present and future leading power factor computer loads.
- Short Circuit Withstand Rating (SCWR) withstand capability: 480V – 65kA, 100kA; 600V – 35kA, 65kA.
- Color touch screen display improve user interface and reduce risk of human error.
- Built-in galvanic isolation provides proper grounding without requiring a neutral.
- Excellent dynamic performance.
- Liebert ActiveStar® Digital Signal Processor (DSP) all digital controls.
- Multi-module configurations provide for greater total capacity and module redundancy.
- Module level redundant components— fans and power supplies.
