    SAC-3 Plus is a semi-wave chamber designed exactly according to the 3m test distance. The innovative dome design and the optimized layout of absorbing materials, as well as the laying of ferrite and partly composite absorbing materials with frequency range from 26MHz to 18GHz can minimize the reflection inside the chamber. Due to the relatively short length of the built-in composite absorbing material, the size of this chamber is smaller than that of the chamber with built-in long-tip split absorbing material. the SAC-3 Plus has superior normalized field attenuation characteristics (±3.5 dB) from 30 MHz to 1 GHz, and the field voltage standing wave ratio (5.5 dB) from 1 GHz to 18 GHz meets the CISPR 16-1 -4 requirements. The standard configuration of this chamber includes 1-4m scanning height antenna towers, turntables, and their controllers.

    Since the introduction of SAC-3 Plus, thanks to the innovative design concept, customizability and superior performance to show an efficient and economical solution to fully meet customer needs, has been widely used by foreign customers.

  • main feature:

    The economical and high-performance solution fully meets the test distance of 3m, and the quiet zone QZ can reach Φ1.2m to Φ2m

    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

    Innovative dome design, with better RF characteristics, can save space, for example, to facilitate the installation of ventilation ducts

    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, the maintenance cost is extremely low, and the number of shielding body and absorbing materials can be reduced

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