The World in Communication
These products offer a convenient way to operate
mass produced 12 V DC equipment such as cell
phones, in car entertainment, professional communi-
cation and telematics equipment, refrigerators, tele-
visions etc. from the 24Vdc mobile electrical systems
found on diesel engined vehicles and vessels.
A Comprehensive Range
There are 5 products in the range from 3A to 24A in
isolated or common earth configurations. They have
been optimised for high volume 24 V DC to 12 V DC
applications such as on heavy goods vehicles, coaches,
buses, construction, forestry and agricultural 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 alumi-
nium extrusion. The low mass Surface Mount Techno-
logy components 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 applica-
tions.
Galvanically isolated units are suitable for marine
applications and come complete with the green tam-
perproof 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
equipment, 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.
