    • 品牌: FRANKONIA

      SAC-3 Square is a semi-anechoic chamber designed completely according to the test distance of 3m, following the traditional square design scheme. SAC-3 has excellent normalized site attenuation characteristics (±3.5dB) from 30MHz to 1GHz, and the site voltage standing wave ratio (5dB) from 1GHz to 18GHz meets the requirements of CISPR 16-1-4. The standard configuration of the darkroom includes an antenna tower with a scanning height of 1-4m, a turntable and their controllers. It presents an innovative concept with its usability, customizability and implementability, resulting in efficient and economical solutions.

  • main feature:

      Traditional square design and high-performance solutions fully meet the test distance of 3m, and the quiet zone QZ reaches Φ2m-Φ3m

      Fully meet CISPR 16-1-4 EMI and ANSI C63.4 (ETSI upgrade version) standards

      Fully complies with IEC/EN 61000-4-3 EMS standard

      The absorbing material laid on the ground can be stored in a chamber for easy use

      Upgradeable for E-Drive (Equipment Load, BlueBox, Battery Powered System)

      More than 90% of the chamber's own products, global factories adopt unified process and quality control

      The chamber project is fully controlled in Germany, with rigorous craftsmanship and construction specifications

      The consistency of the absorbing material is excellent, and the simulation results have real guiding significance for the design

      Prefabricated modular ferrite mounting technology saves installation time and provides consistent workmanship

      Unique nano-material absorbing material, replacing traditional carbon powder technology

      The absorbing material has excellent performance and good stability, and there is no problem of aging and sagging. If the performance drops within 10 years, the absorbing material will be replaced free of charge.

      The absorbing material is completely non-combustible, and it is the only absorbing material in the world that meets the requirements of DIN4102 A2 fire protection level, avoiding fire incidents in chambers that may be caused by heat generation

      The chamber meets the cleanliness requirements, ISO 14644-1 class 5, and the materials are non-toxic

      The absorbing material is moisture-proof, and there is no requirement for the humidity of the use environment, and it can be directly maintained with a vacuum cleaner

      The absorbing materials can be replaced with each other, and the maintenance cost is extremely low

      The newly designed three-knife and three-reed screen door has better performance and convenient maintenance

      turnkey solution
