The scalable Liebert NX 225-600kVA UPS is a transformer-free, high efficiency, on-line UPS. The UPS operates with unity power factor, providing more real power for data center equipment. Liebert NX allows Softscale™ capacity upgrades without increasing footprint — 225 to 250 to 300kVA; or 400 to 500 to 600kVA 480V, 60 Hz UL models.

 

• * More watts for your money – Unity Power Factor rated
• * Intelligent Eco-Mode is standard in every system – no upcharge for this feature or for the continuous-duty static switch
• * Reduced operating costs – up to 95% efficiency at partial load conditions during normal operation. Up to 98% efficiency in both partial and fully loaded conditions during Intelligent Eco-Mode operation
• * Large, user-friendly touch screen display

 

FEATURES

	* High energy efficiency in normal mode and Intelligent Eco-Mode™ operation
	* Softscale™ modularity allows capacity growth without increasing footprint
	* Life.net remote monitoring and reporting ensures UPS health
	* Liebert Services local support and 24x7 call center

 

BENEFITS

Flexibility

	* Softscale technology conserves capital while providing an economical expansion path with minimal disruption.
	* Simple 1+N paralleling provides low initial cost and additional levels of redundancy.
	* Parallel up to 6 systems for capacity or redundancy.
	* High power density and small footprint deliver more kilowatts per square foot for efficient space utilization.
	* Automatically adapts to dynamically changing load power factors (leading and lagging) without derating, modification or recalibration.and is more robust and reliable than a momentary static switch design. Higher overload capacity results in more robust operation.

 

Higher Availability

• 	* True on-line, double conversion technology corrects for all types of power fluctuations.
  	* Provides the highest output power quality, with advanced inverter control technology.
  	* Optional dual bus synchronization of multiple UPS units when feeding independent distribution paths. Continuous-duty static switch standard - enables Ecomode operation,

 

Lowest Total Cost of Ownership

• 	* Provides high efficiency in both double conversion and Intelligent Eco-Mode operation – up to 98% efficiency.
  	* Active IGBT Rectifier reduces size requirements for generator sets, circuit protection, cabling and transformers, minimizing installation and operation costs.
  	* Optimizes battery life with temperature-compensated battery charging in both double conversion and Intelligent Eco-Mode.
  	* Supports a full range of leading and lagging power factor loads without derating. Unity input and output power factor ratings deliver more real power for your money.
