If you need to fit 24V equipment onto a 12V electrical system, then an "up" converter from the DD Series offers a fast and easy way to configure your system. With a range from 72W (3A output) to 600W (25A output), these products offer state of the art designs for fast installation and long term reliable operation.
All products fit onto a “Click ‘n’ Fit” mounting clip which is fixed in three points allowing it to be mounted on uneven surfaces. It is easy to fit the clip into awkward places and then simply click the unit into position.
