Performance values (without options) refer to +25 °C ambient temperature. 1) in accordance with IEC 60068-3-5. 2) free field, 1 m distance from the front, as per DIN 45635, part 1, accuracy class 2. 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 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.
For monitoring and controlling the test chamber is equipped
with a powerful 32-bit control system M!NCON/32.
The terminal with LCD-display “MINCONTROL” offers input
and display of values and states IP54 certified switch cabinet.
Extremely quiet
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.
