About Demke Electronic
Demke Electronic specializes in the development and manufacture of DC/DC converters. The portfolio includes non-isolated step-down converters (buck), buck-boost step-up/step-down converters, galvanically isolated converters up to 800 W, and compact isolated converters for THT PCB mounting from 3 W to 30 W. The devices cover output powers from 1 W to 1200 W and offer ultra-wide-range inputs of up to 1:10 for systems from 12-V lead-acid to 160-V lithium as well as supercapacitor systems. The converters operate with efficiencies of up to 99 % without thermal power derating at ambient temperatures from −40 °C to +85 °C. The assemblies are built in aluminum housings with full PU encapsulation (up to IP69K) and are designed to withstand vibration, moisture and dirt. In addition to standard products, the company offers custom converters — from modified standard units to entirely new developments — as well as engineering services ranging from circuit design and prototype construction to series production, optionally as white-label. Applications are found in industrial trucks, battery and supercap systems, mobile robotics, e-mobility, renewable energies, rail technology, and aerospace.
