Thyrobox DC 3 from AEG Power Solutions fulfills the high requirements of power supply 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 sine wave form and the system has a high power factor. Thyrobox DC 3 is based on proven B12 Thyristor Rectifier and IGBT chopper technology. Due to the wide output voltage range, load voltages from 50 V up to 700 V can be realized. The smallest Thyrobox DC 3 has an output current of 1,800 A, which can be modularly expanded to 7,200 A. The robust and compact design of the Thyrobox DC 3 enables utilization even in harsh environments.
