About RSG Electronic

RSG Electronic Components was founded in 1988 in Offenbach am Main as a specialty distributor of passive and frequency-control components as well as power supply equipment, and today, as a brand of Acal BFi Germany GmbH, is part of the British discoverIE Group (LSE: DSCV). The company develops and produces custom switching power supplies and inverters in the power range up to approximately 25 kW ("Custom Power") and distributes standard AC/DC power supplies and DC/DC converters from 0.25 W to 3,200 W, including its own R-Series® DC/DC portfolio. In addition, RSG distributes quartz crystals and oscillators for frequency control as well as products from international technology partners such as AdapterTech, Cincon, P-Duke, Protek and TDK-Lambda. Design-in support includes feasibility analyses, EMC pre-compliance measurements, topology optimization (EMC, thermal management, cabling) and approval support; the company also offers calibration, repair and logistics services. Target industries are medical technology, renewable energy, industrial manufacturing, transportation (including railway technology) and defense. Since the merger with Acal BFi Germany GmbH in August 2020, the company is based in Dietzenbach.
