The 6th generation of our custom-made IGBT converters is particularly suitable for more zone block heating systems and crucible furnaces with a higher output due to its modular design. A rectifier, as a B6 or B12 pulse version, supplies the modules with a maximum power of 3600 kW with continuous power distribution. Depending on the application, operating frequencies between 25 Hz and 2000 Hz are possible, as well as operation without compensation (direct converter). The low-loss power components have their own liquid cooling. The quality components, mainly sourced from Europe and America, are assembled in our German plant in Iserlohn.
