These products offer a convenient way to operate mass
produced 12Vdc equipment such as cell phones, in car
entertainment, professional communication and telematics
equipment, refrigerators, televisions etc. from the 24Vdc
mobile electrical systems found on diesel engined vehicles
and vessels.
A Comprehensive Range
There are 10 products in the range from 3A to 24A in isolated
or common earth configurations. They have been optimised
for high volume 24Vdc to 12Vdc applications such as on heavy
goods vehicles, coaches, buses, construction, forestry and agri-
cultural vehicles, commercial and leisure marine vessels.
Tamper Proof
There are no ventilation holes to permit stray objects, dust or
water droplets to enter the case. There are no external fuses
to be tampered with. Fuses will only blow if there is a fault so
there is no need to make them accessible.
All voltage converters are enclosed in a rugged aluminium
extrusion. The low mass Surface Mount Technology compon-
ents are also less prone to damage from vibration and shock,
further increasing the reliability of the units.
3Amp units are excellent for charging mobile phones, while
6A units suit a variety of mobile radio applications.
Galvanically isolated units are suitable for marine applications
and come complete with the green tamperproof label for
petrochemical applications.
Fast Installation
All the units consume an off load current of less than 15mA,
which is probably less than the self discharge current of the
vehicle’s battery. In most cases this can be ignored, speeding
the installation by removing the need to fit a remote switch.
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. A red LED indicates when there
is output from the converter. This gives reassurance to the
installation engineer and speeds fault finding.
Easy 6 Step Installation Method
1. Find a convenient location away from sun and rain.
2. Using the mounting clip as a template, mark fixing positions.
3. Drill screw holes.
4. Fix bracket using screws provided.
5. Clip voltage converter to mounting bracket.
6.Correctly connect to load.
Typical Applications
Installations of mobile and cellular radio communications equip-
ment, telemetry systems, refrigeration, televisions etc on trucks,
buses, forestry and off road vehicles as well as boats and yachts and
a variety of industrial applications. For a wider range of input and
output voltages, see the DD Series.
