The present document contains requirements and measurements methods for the physical interface "A" that is situated
between the power supply system(s) and the power consuming ICT equipment.
The nominal voltage at power interface "A" of ICT equipment defined in the present document is DC voltage -48 V.
The DC power can be supplied by a DC output power system (e.g. based on AC rectifiers on grid or DC/DC converters on
solar system, fuel cell, DC engine or fuel cell generator) and also directly supplied by a battery backup in this DC power
system. The purpose of the present document is to use a power supply system with the same characteristics for all ICT
equipment defined in the area of application:
- to facilitate inter working of different types of load units;
- to facilitate the standardization of ICT equipment;
- to facilitate the installation, operation and maintenance in the same network of ICT equipment and systems
from different origins.
The present document aims at providing electrical compatibility between the power supply equipment and the power
consuming ICT equipment, between different system blocks and loads connected to the same power supply feeding the
interface "A" (e.g. control/monitoring, cooling system, etc.).
The requirements are defined for:
- the power supply input of any type of ICT equipment installed at telecommunication centres that are connected
to interface "A" powered by DC;
- any type of ICT equipment, installed in access networks and customers' premises, the DC interface "A" of
which is also used by equipment requiring a DC supply source;
- any type of ICT equipment powered by DC, used in the fixed and mobile networks installed in different
locations such as buildings, shelters, street cabinets.
Disturbances on the power supply interface "A" relating to the continuous wave phenomena below 20 kHz are covered
within the present document.
The present document does not cover safety requirements, they are covered by relevant safety standards.
The present document does not cover EMC requirements, they are covered by relevant EMC standards.
NOTE: Annex B gives guidance on -60 VDC supply systems.

Okoljski inženiring (EE) - Napajalni vmesnik na vhodu informacijske in komunikacijske tehnologije (IKT) - 2. del: Enosmerna napetost - 48 V (DC)

Ta dokument vsebuje zahteve in meritvene metode za fizični vmesnik »A«, ki je med napajalnim sistemom/sistemi ter informacijsko in komunikacijsko tehnološko opremo (ICT), ki porablja električno energijo.
Nazivna napetost pri električnem vmesniku »A« informacijske in komunikacijske tehnološke opreme, določena v tem dokumentu, je enosmerna napetost – 48 V.
Enosmerno napajanje lahko poteka prek električnega sistema z enosmernim tokom (npr. temelječega na usmernikih na izmenični tok na mreži ali enosmernih pretvornikih v solarnem sistemu, gorivni celici, motorju na izmenični tok ali generatorju gorivne celice), poleg tega pa je na voljo tudi neposredno napajanje z baterijskim pomožnim sistemom v tem sistemu napajanja z enosmernim tokom. Namen tega dokumenta je uporaba napajalnega sistema z enakimi značilnostmi za vso informacijsko in komunikacijsko tehnološko opremo, ki je določena za področje uporabe, za:
– omogočanje medsebojnega delovanja različnih vrst napajalnih enot;
– omogočanje standardizacije informacijske in komunikacijske tehnološke opreme;
– omogočanje nameščanja, delovanja in vzdrževanja informacijske in komunikacijske tehnološke opreme ter sistemov različnega izvora v istem omrežju.
Cilj tega dokumenta je zagotavljanje električne združljivosti med napajalno opremo ter informacijsko in komunikacijsko tehnološko opremo, ki porablja električno energijo, med različnimi sistemskimi bloki in obremenitvami, povezanimi z istim virom napajanja, ki napaja vmesnik »A« (npr. enota za nadzor/spremljanje, hladilni sistem itd.).
Zahteve so določene za:
– napajalni vhod vseh vrst informacijske in komunikacijske tehnološke opreme, nameščene v telekomunikacijskih središčih in povezane z vmesnikom »A«, ki se napaja z enosmerno napetostjo;
– vse vrste informacijske in komunikacijske tehnološke opreme, nameščene v omrežjih za dostop in prostorih strank, pri katerih vmesnik »A« z enosmerno napetostjo prav tako uporablja oprema, ki zahteva napajanje z enosmernim tokom;
– vse vrste informacijske in komunikacijske tehnološke opreme z enosmerno napetostjo, ki se uporablja v stacionarnih in mobilnih omrežjih, nameščenih na različnih
lokacijah, kot so stavbe, pokriti prostori, cestne omarice.
Motnje v napajalnem vmesniku »A«, povezane s pojavom trajnega vala pod 20 kHz, so opisane v tem dokumentu.
Ta dokument ne opisuje varnostnih zahtev; opisane so v ustreznih varnostnih standardih.
Ta dokument ne opisuje zahtev za elektromagnetno združljivost; opisane so v ustreznih standardih za elektromagnetno združljivost.
OPOMBA: Dodatek B vsebuje usmeritve za napajalne sisteme z enosmerno napetostjo – 60 V.
