Currently, there is no dedicated international product standard specifically governing EMC testing for AI data centers. Instead, verification procedures still rely on familiar frameworks such as CISPR 32, CISPR 35, and harmonic requirements. However, the unique characteristics of AI data centers present new challenges: high-power three-phase electrical systems, ultra-high-speed and high-volume dat...[+more]
