Benefits

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.

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.

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.
