Quasar is a software framework for generating OPC-UA servers, mostly used to control power supplies at CERN. The technology provides an efficient and secure infrastructure for communications in automation systems, critical for operations and process control. In 2016, CERN established collaboration and joint ownership agreements with CAEN & ISEG, promoting the joint development of OPC-UA servers for their hardware, but at the same time allowing them to commercially exploit these servers and address new markets. In 2018, CERN signed a new collaboration and joint ownership agreement with WIENER Power Electronics GmbH, the third and last main power supply manufacturer at CERN
