Question: Which IEC standard applies to equipment with an input current of greater than 16 A per phase for harmonic current emissions in the context of Multi-Standard Radio (MSR) Base Station (BS) Electromagnetic Compatibility (EMC)?
Option 1: IEC 61000-3-2
Option 2: IEC 61000-3-12
Option 3: IEC 61000-3-3
Option 4: IEC 61000-3-11
Explanation: In the context of MSR Base Station EMC, specifically for harmonic current emissions at the AC mains input port, equipment drawing more than 16 A per phase must comply with IEC 61000-3-12. This standard is particularly relevant for higher power consumption scenarios, ensuring electromagnetic compatibility and mitigating potential disturbances in the electrical supply network.
