I. Main Application:
1. Prevent the leakage of confidential information during the operation of computer, network servers, switches, and other communication electronic equipment.
2. Prevent interference from external electromagnetic waves during the operation of the aforementioned equipment to ensure its normal functioning.


II. Structural Composition:
1. Shielded Housing: A fully enclosed box made of cold-rolled steel plate, which is焊接 by welding and treated with galvanizing and paint for corrosion protection.
2. Shielded Door: A door assembly consisting of shielded springs meticulously crafted and processed, and cold-rolled steel plates welded together.
3. Filters: The power filter features a broad suppression frequency band and high insertion loss.
4. Ventilation waveguide windows: Cellular ventilation waveguide windows available in sizes of 300*300mm or 200*200mm (special sizes available upon request). Equipped with several microaxial fans in the top waveguide window, each with an air exhaust volume of 1.4m3/min.
5. Other: Transmission interfaces and electrical outlets can be configured according to customer requirements.
