Summary

Recommendation ITU-T K.152 specifies requirements for radiated and conducted emissions from power equipment installed in telecommunication facilities. Power equipment within the scope of this Recommendation includes rectifiers that supply direct current (DC) voltages of up to 400 V, power-conditioning systems (PCSs) including grid-connected power converters (GCPCs), uninterruptible power supplies (UPSs). The power equipment usually includes power conversion devices and may generate conducted and radiated electromagnetic disturbances and cause degradation of the performance of telecommunication systems that Recommendation ITU-T K.152 aims to prevent.
