VT 4021 / 7021 EMC

EMC shielding with temperature

The temperature test cabinets series VT 4021 / 7021 EMC are equipped with optimal shielding attenuation with a test space volume of approx. 200 litres and a temperature range from -35 °C/-65 °C to 100 °C. The shielding attenuation was measured and certified by the Institute for Electric Energy Systems and High-Voltage Engineering (EH) of the University of Karlsruhe (TH).


  • EM-Code xxx55*x / *) up to 3 GHz
  • For monitoring and controlling the test chamber is equipped with a powerful 32-bit control system S!MPAC*
