Description

General features

High efficiency reduces total cost of ownership

  • DPA 250 S4 can reduce energy losses by more than 30% compared to similar products in market
  • Thanks to 3-level interleaved technology the DPA 250 S4 achieves an energy efficiency of over 97% in a wide operating range
  • Extra VFI-double conversion mode maximizes efficiency under low-load conditions

Full flexibility to meet a variety of installation schemes

  • Small installation footprint salves space DPA 250 S4 is adaptable to different installation schemes
  • Variety of options for energy backup. Including lithium-ion batteries
  • The DPA 250 S4’s battery charger is very powerful, ready to support the critical load in the next outage

Uninterruptible power – scalable from 50 kW up to 1.5 MW
