Introduction With the massive development and convergence of Telecom and IT, there are more and more customer Premises Equipment such as ICT devices terminals and home netwo
20、rk. Each of them requires an electric adapter and an AC plug to be powered. That creates a forest of cables and energy losses, so the need of mutualising power at the level of a room with a SELV DC network has appeared with the benefit of reducing the amount of adapters and plugs, reducing by the wa
21、y quantity of material used (plastic, copper, electronic) and thus reducing electronic wastes. In addition this will allow simpler reuse of the output of this common power supply for new ICT devices by using the universal power adapters for fixed devices as standardized by ETSI and recommended by IT
22、U-T. There would also be a significant saving on power consumption from a better efficiency on a wide range of power and reduced no load power losses. For each of USB-A charger avoided by connecting a USB-A detachable charging cable to the DC network, it has been roughly assessed for 1 Billion units
23、, a potential saving of 100 000 tons of power supply material, and 2 TWh consumption, 1 million tons of CO2 emission each year. Other benefits are offered to users in the zone or room where the SELV DC networks operate such as autonomy by the battery and grid energy cost reduction by using renewable
24、 energy sources, PV being the easiest to install having a very long lifetime. Moreover, it is an enabler and extender of telecom service use in emerging countries where there is no electricity grid and it brings at the same time some additional electricity for other use such as lighting with LEDs. F
25、inally, the SELV distribution is the natural extension in rooms of the Building 400 VDC distribution when it will be widely spread as it seems to be a useful complement to distribution AC to offer more resilience to disaster and improve efficiency and use of renewable energy at building level in sma
26、rt cities and micro grids. ETSI ETSI TR 103 229 V1.1.1 (2014-07) 61 Scope The present document specifies a Safety Extra Low Voltage DC power supply unit for powering at home or in public area (stores, hotels, railway stations, etc.) any ICT devices equipped with DC input or any ICT adapter with DC i
27、nput compliant with EN 300 132-3-1 i.17. It gives information on: architecture with multi-outputs or DC network and powering area (room, zone); input and output voltage interface; configuration of interface voltage; optimization of efficiency and cost by mutualising several devices on the same DC po
28、wer system; compatibility with future building using the up to 400 VDC power interface defined in EN 300 132-3-1 i.17; integrated power shutdown management, to save energy as much as possible; reliability; EMC and resistibility; power autonomy to enable standalone power of ICT in case of crisis (ele
29、ctric grid failure, climatic crisis, earthquake, etc.); possibility to use renewable energy especially in emerging countries with no grid or of poor quality grid: which input interface, and how to make the sizing? possibility to power devices other than ICT such as low power light which highly incre
30、ases life quality and sustainable development; some information on product safety; ecodesign principles with assessment of gains in mass of material use, energy and CO2 emission. The present document also gives an overview of other existing standards in the field. The detailed description of power g
31、enerators and power converters or controllers are out of the scope. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
