SIST EN 300 132-1 V2.2.1:2023
(Main)Environmental Engineering (EE) - Power supply interface at the input to Information and Communication Technology (ICT) equipment - Part 1: Alternating Current (AC)
Environmental Engineering (EE) - Power supply interface at the input to Information and Communication Technology (ICT) equipment - Part 1: Alternating Current (AC)
The present document contains requirements for the input of the ICT equipment connected to interface "A1".
The voltage at interface "A1" defined in the present document is single phase and three phase AC.
The following voltage range categories are covered:
• Narrow single phase "A1"n-1p and narrow three phase "A1"n-3p AC voltage range defined to comply with
nominal European AC voltages defined in IEC 60038 [i.2].
• Wide single phase "A1"w-1p and wide three phase "A1"w-3p AC voltage range for worldwide nominal AC
voltages. This wide voltage range is based on the nominal voltages defined in IEC 60038 [i.2].
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 "A1" (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 "A1" 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.
Okoljski inženiring (EE) - Napajalni vmesnik na vhodu v opremo informacijske in komunikacijske tehnologije (IKT) - 1. del: Izmenični tok (AC)
Ta dokument vsebuje zahteve za vhod opreme informacijske in komunikacijske tehnologije (IKT), povezane z vmesnikom A1. Napetost v vmesniku A1, opredeljena v tem dokumentu, je enofazna in trifazna izmenična napetost. Obravnavane so naslednje kategorije napetostnega območja: • ozko enofazno A1n-1p in ozko trifazno A1n-3p AC napetostno območje, ki je skladno z nazivnimi izmeničnimi napetostmi v evropskem prostoru, opredeljenimi v standardu IEC 60038 [i.2]; • široko enofazno A1w-1p in široko trifazno A1w-3p AC napetostno območje za nazivne izmenične napetosti po vsem svetu. To široko napetostno območje temelji na nazivnih napetostih, opredeljenih v standardu IEC 60038 [i.2]. Cilj tega dokumenta je zagotavljanje združljivosti med napajalno opremo ter opremo informacijske in komunikacijske tehnologije ter tudi med različnimi napajalnimi enotami, povezanimi s takim vmesnikom A1 (npr. enota za nadzor/spremljanje, hladilni sistem itd.). Namen tega dokumenta je: • opredeliti napajalni sistem z enakimi karakteristikami za vso opremo informacijske in komunikacijske tehnologije, ki je določena za področje uporabe, pri čemer je področje uporabe lahko katera koli lokacija, na kateri se uporablja vmesnik A1, npr. telekomunikacijska središča, radijske bazne postaje, podatkovna središča in prostori strank; • omogočiti standardizacijo napajalnih sistemov za opremo informacijske in komunikacijske tehnologije;• omogočiti nameščanje, delovanje in vzdrževanje opreme ter sistemov informacijske in komunikacijske tehnologije različnih izvorov v istem omrežju; Splošne zahteve za varnost in elektromagnetno združljivost so zunaj področja uporabe te skupine dokumentov, razen če posebne zahteve niso opredeljene v obstoječih varnostnih standardih ali standardih za elektromagnetno združljivost. Ta dokument se navezuje na zahteve za vmesnik med opremo informacijske in komunikacijske tehnologije ter njenim napajanjem. Vključuje zahteve v zvezi s stabilnostjo in meritvami vmesnika. Različne druge reference ter podrobne ureditve meritev in preskusov so navedene v informativnih dodatkih.
