Class leading availability
Three-phase UPS 10-250 KW


Highly scalable, unbeatable efficiency and compact design

From 10 to 250 kW, PremiumTower™ is a Swiss made three-phase, online double-conversion Uninterruptible Power Supply. Configurable as a standalone UPS or as a parallel multi-cabinet system, PremiumTower provides the ultimate flexibility for future growth. PremiumTower offers scalability of up to 7.5 MW and delivers unbeatable energy efficiency in a robust and compact design. The flexibility in the number of battery blocks (20 to 50), eliminates the need to oversize the batteries and allows system designers to optimize cost versus autonomy time. Internal battery options, or matching battery cabinets, avoid complex installations and make PremiumTower the best solution for applications where power performance, available space, and flexibility are key parameters.

  • Unbeatable efficiency 96.6% (VFI)

  • Increased nominal rating (kW = KVA)

  • Near unit input power factor at full or partial loads

  • Compact mechanics with only 0.36 m2 for 120 kW

  • Ease of service with front access only

  • 5 times higher charging current than typical stand alone UPS


Up to
415 KW/m2

Advanced Performance

  • High reliability by design

    Three independent power converters increase system reliability and provide power continuity even in cases of power component failure.

  • High battery charging current

    With the ability to provide up to 5 times more charging current than typical standalone, PremiumTower reduces the total system cost by eliminating the need for external battery chargers

  • Outstanding overload capacity

    With a 120% continuous operation in overload condition, mission-critical applications can be safe in the event of unexpected load demands.

  • Short circuit capability

    With a Short Circuit capability of 3 times nominal current (3 x In), PremiumTower is able to clear output circuit protection in milliseconds.

Lowest Total Cost of Ownership

High efficiencies in partial and rated loads
  • High efficiencies in VFI and ECO mode

    PremiumTower provides optimized partial and full load efficiencies of up to 96.6% in online double-conversion mode. In Ultra-Safe ECO mode the UPS provides an excellent power quality with 99.4% efficiency

  • Minimized footprint (save of valuable floor space)

    PremiumTower optimizes valuable floor space, from 0.29 m2 (for 10 - 60 kW) to 0.6 m2 (for 250 kW), internal battery options (10 - 60 kW) eliminate the cost of additional battery cabinets and simplifies the installation.
