Kohler MF1500 DPA

Exceptionally resilient, flexible and scalable high power modular UPS. With best-in-market 97.4% VFI mode energy efficiency, this UPS redefines lifetime cost for data centres and other high density applications without compromising reliability.


Modular Format. Maximum Flexibility. Minimised Footprint. Market-leading efficiency

The Kohler MF1500 DPA has been designed with a clear goal that reliability does not require excess, and high power can exist alongside efficient use of energy. This modular UPS system combines proven DPA technology with the latest advances in components and software.

With innovative, vertical slide-in modules, the MegaFlex enables resilient, high power density protection by reducing UPS footprint by up to 45% over traditional approaches, without compromising access for installation and maintenance.

That protection is achieved with best-in-market 97.4%  VFI energy efficiency, reducing environmental impact, optimising PUE measures, and delivering significant financial savings in energy and cooling costs.

  • 250 kW – 1500 kW – parallelable to 6000 kW
  • Slide-in vertical modules
  • Market-leading 97.4% efficiency
  • Cable-free internal connections
  • Extra-long life wear parts

Maximised Availability with Decentralised Parallel Architecture

Decentralised parallel architecture products contain all the essential components of a UPS within each module, allowing independent operation.

DPA modules can be hot-swapped, without affecting the rest of the system, easing maintenance, reducing system repair times, and dramatically increasing availability.

Best-in-market efficiency

Advanced components enable delivery of up to 97.4% efficiency at system level in VFI mode, across a wide, practical load band.

Efficiency at low loads is enhanced further by Xtra VFI mode functionality – this optimises load across modules.

Engineered. Inspired. Informed

Engineered for ease and safety, each hot-swappable, slide-in 250 kW module uses cable-free connections.

Inspired by feedback from users on what really matters, the advanced design also maximises the life of consumable / wear parts such as fans and capacitors, with replacement of such items required only once in a 15 year period.

Informed by trends to require more power from less space, the innovative physical design also allows a power density of up to 493 kW/m2, around 45% better than traditional formats.
