Modern battery-powered electric vehicles often use primary main battery voltages between 350V-650V. As in all vehicles, these must be converted to 12V or to 24V to supply various electrical consumers such as lighting, infotainment, and many more. The robust DC/DC converter 729-24-SD is highly integrated in terms of broadband EMC filter, advanced control technology, state-of-the-art power semiconductors and energy storage elements. The PU potting makes it robust to shock and vibration and can be widely used for applications such as construction machinery or other vehicles.

Our converters also bring the horsepower to the ground in E-Trucks. The DC-Transformer 151DH-13.8-On with 13.8V output voltage and 280 Watt power is installed in the new series of the most powerful FUTURICUM E-Trucks with over 680 HP as a 13.8V battery charging converter and 12V power supply.

This performance upgrade includes a power increase of 35W with a simultaneous noise reduction. Demke DC-Transformers have always been optimized for maximum efficiency with minimum noise emission - we continue to pursue this goal consistently.

No other Demke DC-Transformer (non-isolated step-down DC/DC converter) as the 145-series is built in several variants, has a higher power density or is more climate-proofed. As a part of our ongoing product management, we have got even more performance from the 52x77x19 mm DC/DC converter.

In order to guarantee the quality of our Demke DC-DC converters under various kinds of environmental impacts, we have to test them under extreme conditions and let them age prematurely.

To make it easier to understand the special characteristics of our DC/DC converters, a characteristic curve plot will be available as take away (PDF) for each article in the future.

Our new E13-certified 450 Watt DC/DC Converter for Automotive and E-Mobility applications is ready for road use and has been installed successfully in the first road legal vehicles. The DC Transformer passed the E13 10R - 05 certification right away, this was a great appreciation for the work of our engineers and motivates for further projects.

Since our company is constantly growing, we have decided to expand our office space. We have enlarged the laboratory space and created a modern lounge area for our engineers and customers. This area is used by our employees to let creativity and know-how flow together. By incorporating the needs of our customers, the first developments of future DC-Transformers are created here, tested and realized in the laboratory right next door.
