10m semi-anechoic chamber

10m semi-anechoic chamber

SAC-10 is a semi-anechoic chamber designed according to the 10m test distance, which is mainly composed of the main anechoic chamber, the control room and the power amplifier room (conduction test chamber can be selected), which is used for the radiated immunity test and the conformity test of radiated emissions at a distance of 10m or 3m. The 10m anechoic chamber is the most popular standard test environment, mainly to meet the testing needs of large-size electronic systems and the requirements of some industry testing standards for electronic products, and can also be tested by 3m method, the quiet area can be expanded to 5m or even 8m diameter or larger, which is widely used in IT products, household appliances, medical equipment, automobile vehicles and parts, large military electronic systems, industrial electronic systems, communications and other electromagnetic compatibility tests. The addition of a drum system can complete the electromagnetic compatibility test items of road vehicles.


Reference configuration


• Typical shield inner dimensions: 21m (length), × 12m (width), × 9m (height).


• Shielding structure: Smart Shield Twin Wall double-layer shielding structure, from the inside to the outside is high-performance composite conical absorber, ferrite, anti-corrosion multi-layer board, shielding steel plate, between two adjacent standard shielding modules with conductive shielding liner Gasket for good RF shielding and electrical contact connection.


• Standard shielding module: 3m ×1m in size, made of 2mm thick double-sided hot-dip galvanized steel sheet with two bends on four sides. The thickness of the double-sided hot-dip galvanized steel sheet is ≥2mm, and the thickness of the galvanized layer is ≥20μm, and the thickness is uniform. The modules are connected by M10 screws with a high strength mark of 8 or more.


• Absorbing structure: The wall absorbing material is composed of low-frequency absorbing material ferrite (100mm×100mm×6.7mm) composed of nickel-zinc-iron-manganese and high-performance EPP absorbing material (can be selected according to needs); Ground movable absorbers are composed of EPP absorbers and ferrite. The wall absorber can be covered with white reflectors to beautify the interior environment and increase brightness.


• Screen door: 2m×2m or 3m×3m or larger and other sizes can be selected, and special size design can also be carried out according to needs.


At the same time, it is equipped with a 0.9m×2m employee access door, which is a manual, semi-automatic and fully automatic track;


• Waveguide window: 600mm×600mm (with flange), up to 18GHz, can be selected according to needs;


• Built-in turntable: diameter of 4m, load of 3 tons, other types of turntable can also be customized according to needs;


• Raised floor: the load is 3 tons/㎡ as the heavy-duty area, and the other areas are 1 ton/㎡, and the height is generally 50cm;


• Filter: 380V, 220V, 110V, DC, etc., as well as network, communication and other signal filters;


• Antenna Tower: up to 4m high, with horizontal and vertical polarization, can be installed with various types of antennas;


• Video system: 2 sets of digital color monitoring system, one set of which is fixed on the wall and 1 set of movable floor;


• Voice system: ensure that the communication between the main dark room and the amplifier room can be unobstructed;


• Fire alarm system: adopts high-sensitivity air sampling and analysis system, which complies with the relevant regulations of the Ministry of Public Security of China on fire prevention products;


• Lighting system: halogen lighting, 1m high from the ground illumination value of 250Lux, can be lifted;


• Lifting platform: It is convenient for large objects to enter and exit the chamber, and the automatic lifting platform is customized according to the size of the chamber door;


• Exhaust system: responsible for discharging vehicle exhaust directly to the dark room to ensure that the air in the dark room is clear and normal;


• Cooling air system: for the normal testing of vehicles or other high-temperature products, provide a cold air strong transmission system;


• Drum system: In order to meet the EMC test standards for road vehicles, the drum system can be customized according to the vehicle type.


Key features
