Fore
17、word This European Standard (Telecommunications series) has been produced by ETSI Technical Committee Environmental Engineering (EE). The present document concerns the requirements for the interface between telecommunications equipment and its power supply, and includes requirements relating to its
18、stability and measurement. Various other references and detailed measurement and test arrangements are contained in informative annexes. The present document is part 2 of a multi-part deliverable covering Environmental Engineering (EE); Power supply interface at the input to telecommunications equip
19、ment, as identified below: Part 1: “Operated by alternating current (ac) derived from direct current (dc) sources“; Part 2: “Operated by direct current (dc)“; Part 3: “Operated by rectified current source, alternating current source or direct current source up to 400 V“. National transposition dates
20、 Date of latest announcement of this EN (doa): 31 January 2008 Date of latest publication of new National Standard or endorsement of this EN (dop/e): 31 July 2008 Date of withdrawal of any conflicting National Standard (dow): 31 July 2008 ETSI ETSI EN 300 132-2 V2.2.2 (2007-10) 6 1 Scope The present
21、 document contains requirements for: - the output performance of the direct current (DC) power equipment at the interface “A“; - the input of the telecommunications equipment connected to interface “A“ powered by DC. The DC voltage at interface “A“ may be derived from the AC primary supply. The DC s
22、upply may incorporate a backup battery. If any other equipment e.g. datacom equipment, are connected to interface “A“ in parallel to telecommunications equipment, all requirements addressed in clause 4 of the present document must be fulfilled. The present document aims at providing compatibility be
23、tween the power supply equipment and the power consuming telecommunications equipment, and also between different system blocks connected to the same power supply. NOTE 1: The present document is applicable only to -48 VDC power supply interfaces. However, during a transitional period, other DC volt
24、ages may be used in existing installations. Annex A gives guidance on working in conjunction with existing -60 VDC supply systems. The power supply interface, interface “A“, is a physical point to which all the requirements are related (see figure 1). This point is situated between the power supply
