How can the EMC limits of low-voltage equipment in an intelligent low-voltage monitoring unit meet the standards?

Time：2026-02-09 Views：23次

Share：

EMC compliance for low-voltage equipment must be considered in advance during the design phase.

Emission limits: based on GB/T 9254 Class B.

Immunity limits: based on GB/T 17626 series.

Compliance measures: select low-radiation components; optimize PCB layout; strengthen shielding; add filtering protection.

Pre-testing: conduct EMC scanning tests during the R&D phase to identify and rectify any exceeding frequency points. Finally, pass third-party laboratory certification testing.

Through system design, all EMC limit requirements can be met, and CE certification can be obtained.
