scope:

This Recommendation specifies a power feeding architecture for power feeding systems of up to 400 VDC at telecommunications centres, datacentres and customer premises [ITU-T L.1200]. This Recommendation aims at providing an architecture reference for an up to 400 VDC power feeding system with high reliability, safety and manageability. This Recommendation covers the following items for power feeding systems of up to 400 VDC:

1) configuration of power feeding systems of up to 400 VDC;

2) requirements of the main basic elements for power feeding systems of up to 400 VDC (rectifiers, power distribution units (PDUs), batteries and distribution power lines);

3) monitoring and management functions.

This Recommendation ensures a safe, operable, electromagnetic compatibility (EMC)-compliant and reliable cohabitation of power feeding systems of up to 400 VDC with AC and -48 VDC [EN 300 132-2] systems in sites combining these power feeding interfaces.

The full description of a battery, grid AC supply, backup generator and power supply units (PSU) in ICT equipment and renewable or distributed energy sources are out of the boundaries of this Recommendation, but indications are given on their influence on the architecture of power feeding systems of up to 400 VDC.
