The Victron Orion-TR voltage dropper is designed to convert an input voltage of 24V DC (in fact anywhere between 18V and 35V DC) into a 12V DC output for use on most electrical items on board boats, motorhomes and other automotive applications. The converter is protected to IP43 and is easy to install with no special tools needed. They are very efficient, running above 95% efficiency due to the use of active rectification (also known as synchronous rectification).
