More details:

• 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. Now 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. Typical applications include the installation of 24V equipment on 12V vehicles and installation of specialist equipment requiring higher operating voltages.
• The latest addition to the range includes two high current (17 and 25 Amps output) units. These use state of the art designs with efficiency up to 93% and practically all components are mounted using computer controlled surface mount technology (SMT). The result is a robust product with low component mass. The mechanical aspects include a brand new casing profile designed for maximum heat dissipation as well as a new design of our highly successful mounting cradle that allows the unit to be fully wired before being “clicked” into place. This provides for a faster installation time with mechanics capable of withstanding long term vibration with no risk of screws falling out.
• 12V–24V converters are available in two casing formats. Units from 72-240W use the standard Alfatronix aluminium casings with polycarbonate endcaps and three point mounting cradle. The larger 400W and 600W units occupy a larger heatsink casing and utilise the heavy duty Phoenix connector. Installation is by way of the larger four point 'I' shaped mounting cradle.
• The DD Series 12–24V products are available in either standard IP53 format (like most Alfatronix converters) or the ruggedised IP65 versions. Just add –RU to the part number. These are suitable where the installation is in a particularly hostile environment and subject to increased water and dirt exposure.
