What are the national EMC standards for low-voltage monitoring equipment in intelligent low-voltage monitoring units?

Time：2026-02-08 Views：5次

Share：

The main national EMC standards for low-voltage monitoring equipment include: GB/T 17626 series (corresponding to IEC 61000-4 series) immunity standards; and GB/T 9254 (corresponding to CISPR 32) radiated emission standards. Specifically: GB/T 17626.2 (ESD), GB/T 17626.4 (EFT), GB/T 17626.5 (surge), and GB/T 17626.8 (power frequency magnetic field). Products must pass testing by a nationally accredited laboratory and obtain a test report. The design should refer to the national standard limits to ensure that the EMC requirements of low-voltage monitoring equipment are met.
