Organization: ITU-T
Publication Date: 1 July 2019
Status: active
Page Count: 20
scope:

This Recommendation defines the emission requirements for electrical equipment that is installed inside or on the roof of telecommunication facilities.

This Recommendation applies to power supply systems with embedded power conversion devices (e.g., DC to AC inverters, DC to DC, AC to DC and AC to AC converters), PCSs including GCPCs, UPSs and air conditioning systems. Lighting equipment is not addressed by this Recommendation.

Telecommunication equipment that directly provides telecommunication services are excluded from the scope of this Recommendation as they are covered by specific EMC Recommendations.

This Recommendation specifies measurement methods and limits for conducted emissions in the frequencies from 9 kHz to 30 MHz and for radiated emissions from 30 MHz to 6 GHz. Guidance on any unintentional voltage/current at AC and DC power ports is provided in this Recommendation.
