Foreword This European Standard (EN) has been produced by ETSI Technical Committee Environmental Engineering (EE). The present document concerns the requirements for the interface between telecommuni
19、cation or datacommunication equipment (so called telecommunications and datacom (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. The
20、 introduced interface operated by DC source up to 400 V is considering power consumption increase and equipment power density increase in order to get higher energy efficiency with less material than with low voltage -48 VDC or permanent AC powering solution. The DC interface could also simplify the
21、 use of renewable energy with DC output such as photovoltaic generator. The present document is part 3-1 of a multi-part deliverable covering Environmental Engineering (EE); Power supply interface at the input to telecommunication and datacom (ICT) equipment, as identified below: Part 1: “Operated b
22、y alternating current (ac) derived from direct current (dc) sources“; Part 2: “Operated by -48 V direct current (dc)“; Part 3-0: “Operated by rectified current source, alternating current source or direct current source up to 400 V, Sub-part 0: Overview“; Part 3-1: “Operated by rectified current sou
23、rce, alternating current source or direct current source up to 400 V; Sub-part 1: Direct current source up to 400 V“; Part 3-2: “Operated by rectified current source, alternating current source or direct current source up to 400 V; Sub-part 2: Alternating up to 400 V solution“; Part 3-3: “Operated b
24、y rectified current source, alternating current source or direct current source up to 400 V; Sub-part 3: Rectified current up to 400 V solution“. The parts 3-0 to 3-3 are the result of a revision of EN 300 132-3 3. This revision was necessary, because the present document was not clear. Sub-parts ha
25、ve been introduced for voltage interfaces A3 up to 400 V. National transposition dates Date of adoption of this EN: 9 February 2012 Date of latest announcement of this EN (doa): 31 May 2012 Date of latest publication of new National Standard or endorsement of this EN (dop/e): 30 November 2012 Date o
26、f withdrawal of any conflicting National Standard (dow): 30 November 2012 ETSI ETSI EN 300 132-3-1 V2.1.1 (2012-02)61 Scope The present document contains requirements for: the output performance of the power equipment at the interface A3; the input of the telecommunications and datacom (ICT) equipme
27、nt connected to interface A3. The voltage at interface A3 defined in the present document is DC voltage between 260 V and 400 V. The DC power can be supplied by the battery backup of a DC power system. The present document aims at providing compatibility between the power supply equipment and both t
28、he telecommunications and datacom (ICT) equipment, and the different load units connected to the same interface A3 (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 telecommunications and d
29、atacom (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 centers, Radio Base Stations, datacenters and customer premises; to facilitate interworking of different (types of) loads; to facilitate the st
30、andardization of power supply systems for telecommunications and datacom (ICT) equipment; to facilitate the installation, operation and maintenance in the same network of telecommunications and datacom (ICT) equipment and systems from different origins. General requirements for safety and EMC are ou
31、t of the scope of the present document series unless specific requirement not defined in existing safety or EMC standards. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific. For specific references, only the cited
32、version applies. For non-specific references, the latest version of the reference document (including any amendments) applies.
