Abstract

This paper reports test results and reviews of the developed DC plug and socket-outlet. The developed item can be applied to the 400 Vdc power to improve energy efficiency in telecommunication sites, data centers, commercial buildings, and smart energy. There are some safety issues to use the 400 Vdc power. The set of plug and socket-outlet has a unique mechanism which based on combination of a permanent magnet and mechanical contact in the limited small space. That should solve the problems such as both arc extinction and protection against electric shock known as critical DC power issue for a long time.
