USB 3.1 / USB Type C Power Delivery

In 1996 the USB 1.0 standard was introduced with a maximum data rate of 12 Mbit/s. In 2000 the USB 2.0 standard was specified with a data rate of 480 Mbps. This is still the most common version of USB in use (as of writing). In November 2008, the USB Implementers Forum introduced the specification for USB 3.0. In SuperSpeed mode, a maximum data rate of 5 Gbit/s is achieved with USB 3.0.

Energy Efficiency Requirements

The statutory requirements have intensified over the years due to the technical progress. California published firstly statutory requirements by the California Energy Commission (CEC), then the EU followed with the Eco Design Directive 2009/125 / EC and finally there were limiting values for the entire US and many other countries. Based on these guidelines, the “International Efficiency Marking Protocol for External Power Supplies” has been developed, which allows a classification of the limiting values into so-called Efficiency Levels.

Certificates for China; CCC or CQC approvals for power supplies

In China, there are two certification systems for product quality standardization, certain product groups are subject to authorization, most of them can be approved voluntarily. The certification is carried out by an approval agency. A self-declaration of conformity with Chinese standards for products subject to approval is not possible. Products which are not subject to certification are not required to be tested by an approval agency. Distribution and import to China, however, are simplified for an approved product.
