ITU-T L.1001 will benefit countries not equipped with reliable AC power grids, as it will be compatible with standalone AC produced by renewable energy sources including the 5V and 12V power interfaces of small photovoltaic systems (solar energy).
Recommendation ITU-T L.1001 will reduce number of adapters that need to be manufactured by widening the range of compatible devices, facilitating adapter reuse and recycling, and increasing build-quality and resilience to over voltages.
Designed to promote an adapter lifespan of at least ten years, the new ITU standard will drive substantial reductions in energy consumption used in information and communication technology (ICT) equipment manufacture, limit device duplication, reduce strain on raw materials and enable enormous reductions in e-waste.
“Our global standard for universal phone chargers received a very warm welcome from vendors and consumers, and I am certain that this new universal power adapter standard will enjoy the same worldwide success. These important environmentally-oriented standards will markedly reduce e-waste and greenhouse gas emissions, while saving money for vendors and consumers through more efficient use of raw materials and energy,” said Hamadoun I. Toure, secretary general, ITU.
The new standard includes basic configurations and general requirements of UPAs and their interfaces: cable; connectors; voltage; current; ripple; noise; energy efficiency; safety; electromagnetic compatibility; resistibility and eco-environmental specifications. The UPAs are designed for ICT devices in people’s homes, and provide a low-voltage input to a device by converting the AC mains voltage to a low-voltage DC output.
Future capabilities could include compatibility with a DC interface from renewable energy systems or power sockets found in transportation systems (boats, trains, planes, buses, etc.).
