DD Series 12-24V UP DD Series 12-24V UP DD Series 12-24V UP Voltage Converters Voltage Converters Voltage Converters 12V-24V UP 400W and 600W 12-24V units NEW Converters for a wide The latest addition to the range includes two high current (17 and 25Amps output) units. These use state of the art designs with range of applications efficiency up to 93% and practically all components mounted using If you need to fit 24V equipment onto a computer controlled surface mount technology (SMT). The result is a 12V vehicle, then an up converter from the robust product with low component mass. The mechanical aspects DD Series offers a fast and easy way to include a brand new casing profile designed for maximum heat dissipation configure your system. Now with a range as well as a new design of our highly successful mounting cradle that from 72W (3A output) to 600W (25A allows the unit to be fully wired before clicked into place. This provides output), these products offer state of the for a faster installation time with mechanics capable of withstanding long art designs for fast installation and long term vibration with no risk of screws falling out. term reliable operation. A Wide Range Applications Typical applications include the installation of 24V equipment on 12V vehicles and installation of specialist equipment requiring higher operation voltages. The new 400W and 600W 12V-24V units shown here with the new Phoenix connector. Supply INCLUDES the mating half and further eases installation The while providing a secure connection reinforced with additional pull resistance. 12V-24V units from 72-240W are available in this format and casing. Also available in IP65 format The DD Series 12-24V products are available in either standard IP53 format (like most Alfatronix converters) but are also available in Ruggedised IP65 versions. Just add RU to the part number. These are suitable where The 12V-24V converters have been used for a the installation is in a variety of applications including bus ticketing particularly hostile systems on mini buses and for 24V bow environment and thrusters on leisure craft.
