NEW 400W and 600W 12-24V units

The latest addition to the range includes two high current (17 and 25Amps output) units.  These use state of the art designs with efficiency up to 93% and practically all components 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 ‘UP' Converters for a wide range of applications

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. 

A Wide Range of Applications

Typical applications include the installation of 24V equipment on 12V vehicles and installation of specialist equipment requiring higher operating voltages. 

Also available in IP65 format

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.
