Scope

With reference to clause 4, the present document contains requirements for:
• the output of the power supply feeding interface A3ac;
• the input of the ICT equipment connected to interface A3ac.
The voltage at interface A3ac defined in the present document is single phase and three phase AC.
The following voltage range categories are covered:
• A3ac-1: narrow single and three phase AC voltage range defined to comply with nominal European AC
voltages [6].
• A3ac-2: wide single and three phase AC voltage range for worldwide nominal AC voltages.
The present document aims at providing compatibility between the power supply equipment and both the ICT equipment,
and the different load units connected to the same interface A3ac (e.g. control/monitoring, cooling system, etc.).
The purpose of the present document is:
• to identify a power supply system with the same characteristics for all ICT equipment defined in the area of
application; the area of application may be any location where the interface A3 is used i.e. telecommunication
centres, Radio Base Stations, datacentres and customer premises;
• to facilitate interworking of different (types of) loads;
• to facilitate the standardization of power supply systems for ICT equipment;
• to facilitate the installation, operation and maintenance in the same network of ICT equipment and systems
from different origins. General requirements for safety and EMC are out of the scope of the present document
series unless specific requirement not defined in existing safety or EMC standards.
The present document concerns the requirements for the interface between Information and Communication
Technology (ICT) equipment and its power supply. It includes requirements relating to its stability and measurement.
Various other references and detailed measurement and test arrangements are contained in informative annexes
