EMC Mini Test Chambers

Limited laboratory area and the need to test directly at the workplace requires compact and quiet devices. Temperature devices in the Mini series satisfy these requirements. In collaboration with the Institute for Electric Energy Systems and High-Voltage Engineering (EH) of the University of Karlsruhe (TH) we have measured the chamber and developed an optimal shield attenuation. The test space is designed so that the interior container takes over a shield function. The shield attenuation (SA) specifies the ability of an electromagnetic shield to reduce or attenuate electromagnetic fields and surface currents. The electromagnetic protection (EM protection) is provided by the complete topology (structure). This consists not only of the metallic shell but includes electric leadthroughs (current, communication, antenna, signal cables) and mechanical leadthroughs (door, tubes, connector panel etc.).The functional capability and serviceability of a product are already ensured at a very early stage in the research and development laboratory. With this series, we are providing the developer and quality assurance an excellent effective electromagnetic shield in combination with the established controlled temperature test chambers.VT 4002 EMC Test space volume l 16Temperature range °C -35 to +100 °C Temperature deviation in time K1 Temperature homogeneity K2Temperature rate of change 1)Heating K/min 5.0Cooling K/min 3.5Heat compensation max.

We reserve the right of changes in construction resulting for technical progress. Electromagnetic compatibility (EMC) is defined as the ability of an electric device to function satisfactorily within its Product Image (Main)electromagnetic environment(interference resistance). This must function without unduly affecting this environment which itself contains other devices (emitted interference).Electromagnetic influences can result in malfunctions of electrical devices and systems (e.g. aircraft, car, railway, ship, etc.). The technical measurement of the electromagnetic compatibility of a system and appropriate protection measures for reduction or suppression of the electromagnetic interference are the subject of numerous research projects.
