Energy Recovery System (ERS)

  • Active recuperation of braking or lifting energy via a motor / generator (electronic braking resistor)
  • Typical drive / braking power <200 kW
  • Typical energy content 1 - 3.6 MJ / 0.3 - 1 kWh
  • Typical load time up to 20 sec, cycle time 60 sec
  • Simple connection through control via voltage droop mode or elaborate energy management
  • Intelligent, adaptive high performance UltraCap modules
  • DC link operating voltages up to 1,500 V
  • Remote monitoring, self-test features
  • Cycle efficiency up to 96%
  • IP65 +, low maintenance, up to 10 million cycles (depending on design)

Applications

  • Electronic braking resistor for electrically operated railways
  • Energy Recovery on diesel engines via auxiliary motor generator
  • Energy recovery in hybrid - fully electric drives
  • Power boost in fuel cell drives
