Thyrobox DC 3 Industrial High-Power DC Power Supply

  • 1,25 MW Rectifier Module
  • 2,5 MW Power Frame
  • 10 MW Power Block

Thyrobox DC3 from AEG Power Solutions fulfills the most stringent power supply requirements for demanding industrial processes: a perfect stability of output voltage for the best current quality and high efficiency performance. In line with the specificities of those processes, power consumption is as close as possible to a sine wave form and the system has a high power factor. Thyrobox DC3 is based on proven B12 Thyristor Rectifier and IGBT chopper technology. Due to the wide output voltage range, load voltages from 10 V up to 1000 V can be achieved with Thyrobox DC3. The maximum output current of each Thyrobox DC3 module is 2000 A. Thanks to its modularity and to the capability of interconnecting up to 8 units into one power block, higher power requirements can be easily met. The robust and compact design of the Thyrobox DC3 enables utilization even in harsh environments.
