For more than 30 years, the RSG® brand stands for custom-designed switch-mode power supplies and standard DC/DC converters with an exceptional value-for-money, addressing all requirements for reliable high-quality power supply solutions.
RSG Electronic Components GmbH was initially founded in Offenbach/Main in 1988 as a special distributor for passive electronic components.Soon, the product portfolio was extended by AC/DC and DC/DC power supplies and inverters, and only few years later an own R&D for custom-designed power supply solutions up to approx. 25kW was established.
In December 2013 RSG Electronic Components GmbH became part of the British discoverIE Group (LSE: DSCV) and functions within the group as the international center of excellence for the development and production of power supplies.
Eventually, in August 2020 RSG Electronic Components GmbH was legally merged with its sister company Acal BFi Germany GmbH at their facility in Dietzenbach. From there we serve our customers in all parts of the world.
Our foundation for a successful partnership with you are high-quality products combined with the know-how to find the perfect solution for your specific requirements.

Since its founding 1977 in Hiddenhausen (North-west Germany) the family-run SOKRATHERM GmbH has been developing, building and delivering compact combined heat and power generation (CHP) units. Around 2,000 compact CHP units with 50 kW to 1 MW of electrical power generate heat and power in a wide variety of buildings worldwide using the highly efficient and environmentally friendly principle of cogeneration.
The CHP plants manufactured in Nordhausen (Thuringia) produce energy from fuels such as natural gas, biomethane, propane gas, sewage gas or biogas and often reach well over 90% reach total efficiency. With the appropriate accessories, they can also generate emergency power, steam, cooling or heat up thermal oil.
All CHP compact modules from the ISO 9001 certified production are intensively tested in a factory test run before delivery and provide comprehensive web-based remote monitoring. Particularly prominent examples of applications are Niederegger Marzipan in Luebeck (GG 402 with absorption chiller), the children's hospital in Buenos Aires (GG 50), the local heating network Flex-KWK in Oberhausen (GG 530 with electric boiler), the Früh Kölsch brewery in Cologne (GG 198 with steam generator) and the "energy bunker" in Hamburg (GG 530 + GG 237).
Core features of the compact cogeneration units are the compact and maintenance-friendly design, the high efficiency and the reliable plant operation. Or in short: compact, efficient, reliable.
