What are the EMC testing items for 3C certification of edge computing boxes?

Time：2025-09-27 Views：506次

Share：

The 3C certification for edge computing boxes is based on GB/T 9254.1-2021 (CISPR 32 Information Technology Equipment Emission Standard) and GB/T 17618-2015 Immunity Standard. Test items include: conducted disturbances at power terminals (1.5-30MHz), radiated disturbances (30MHz-6GHz), harmonic currents (GB17625.1), voltage fluctuations and flicker (GB17625.2), electrostatic discharge (GB/T17626.2), electrical fast transients and bursts (GB/T17626.4), surges (GB/T17626.5), conducted immunity (GB/T17626.6), 3V/10V power frequency magnetic fields (GB/T17626.8), voltage sags (GB/T17626.1), and 0% voltage dips (GB/T17626.1). 70% of the components offered by ET Electronics are mature and compatible for each test, such as the CMZ3225A-501T common mode inductor for conducted interference, the 5.0SMDJ33CA surge inductor, the ESD0524P edge box for TVS, and the edge box for electrostatic discharge. This configuration ensures that you can pass 3C certification and obtain the certificate.
