DC/DC Converter with 13.8V output voltage and 300W for battery applications

DC/DC voltage converter with 13.8 VDV output voltage up to 300W galvanically non-isolated power

The supply voltage of 48V battery systems with lead-acid or Li-ion batteries can rise up to 59V (e.g. with 14 cells x 4.2Vmax) in maximum charged condition. For very dynamic supply voltage, strong voltage changes (large dV/dt) can occur, which come close to the breakdown voltage of the 63V components

Therefore, with the 142 and 162 series, we have designed the specifications for 70V continuous operation; permissible voltage peaks may be 75V.

Customers who already use Demke DC/DC converters know that even at 75V Vpeak, there are still additional reserves available, so the battery charging converter with its 13.8V output contributes to the full operational reliability of the electrical system.

With the new 142 and 162 series of non-isolated DC/DC converters, Demke once again highlights its ability to compete against low-cost competitors with extremely stable products specified with sufficient reserves. Against the trend of more power and derating or fewer reserves and performance, we are confidently breaking new ground in electromobility with our decentralised and highly reliable DC/DC converters.

Especially the compact and highly integrated DC/DC converter 142E-13.8-SD (supply voltage 16VDC...70VDC) with 13.8V output voltage and up to 15A short circuit current (200W power) is ideal for mobile battery electric applications. Climate safe, vibration resistance, PU potting, internal reverse polarity protection diodes on the output side, high-performance control loop, wide band EMC filter - compact and combined in one device, ready for tomorrow's challenges.
