RSG®: we energize electronics! A Brand of Acal BFi Germany

DC/DC converters, AC/DC power supplies and customized power solutions up to the kW range.

For more than 30 years, the RSG® brand stands for power supply solutions in the upper power range of around 25kW for industrial, medical, military and renewable energy sectors ("Custom Power").

In "Standard Power" we sell AC/DC switching power supplies and DC/DC converters in the lower and medium power range (0.25W - 3,200W) to customers in all above mentioned sectors. We also represent global quality brands, such as AdapterTech, Cincon, Protek, P-Duke and TDK-Lambda. RSG was initially founded in Offenbach/Main in 1988 as a special distributor for passive components and power supply devices. In December 2013 RSG 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 the GmbH was legally merged with its sister company Acal BFi Germany at their facility in Dietzenbach. From there we serve our customers in all parts of the world. The know-how reached in the field development of complex custom-designed power supplies flows into product selection and customer advice in the area of standard solutions. Acal BFi Germany GmbH is certified according to ISO 9001: 2015 and AEO.

Benefit from our technical experience during your design-in with a feasibility study, EMC pre-compliance measurements, topology optimization (EMC, heat dissipation, cabling, etc.) and the necessary approvals.
