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.

Minimum shelf-life for storing electronic devices

The "shelf-life" of an electronic device is significantly influenced by its aluminum electrolytic capacitors ("E capacitor"). This is what the analysis of shelf-life with its usual calculations of longevity and reliability initially has in common.

Flush-mounted Power Supplies: Seeing the unseen

For easy installation and protection against vandalism.

With a maximum diameter of just 51mm, these units are ideal for installation in all standard flushmounted sockets and can be fully hidden in walls.

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.
