Applications
The Demke DC-Transformer 755-24-SD is an galvanically isolated DC/DC Buck-Boost converter and is specially designed for 24V, 48V and 80V supply systems. Thanks to its ultra-wide input voltage range, the DC/DC converter operates accurately within the specified input voltage range even if the input voltage deviates statically by +/- 30% from the previously mentioned DC-supplies. News article available.
