for use on vehicles, vessels and aircraft
of light aircraft. Consequently they are manufactured
at low cost and offer excellent value for money. All
the products may also be used for constant voltage
lead-acid battery charging providing the battery
manufacturers guidelines are followed.
All the PowerVerter products are CE marked,
e-marked and meet the requirements of FCC Class B.
Secure Isolation
It’s your choice. The PowerVerter range offers an
isolated option at every power rating. Some vehicle
manufacturers, such as Scania, require that “the
converter shall be ground loss protected”. This
means that the output voltage shall not
exceed the specification if the supply
ground connection and/or the load ground
connection is lost. This requires an isolated
converter. Isolated converters also prevent
a direct connection between the 24Vdc
input and the 12Vdc appliance in the case
of a semiconductor failure.
Cool Running
The converters operate with a power conversion
efficiency as high as 93%. This results in very little
heat being generated. The reliability of semiconductors
is inversely
24Vdc to 12Vdc
Converters
These products offer a convenient way to
operate mass produced 12Vdc equipment,
such as cell phones, in car entertainment
equipment, professional communication
equipment, telematics equipment,
refrigerators, televisions, etc. from the
24Vdc mobile electrical systems found
on diesel engined vehicles and vessels
and the 28Vdc systems found on aircraft.
These cool running products use
switch mode technology and are assembled
using surface mount technology.
All the products are CE marked, e
marked and meet the requirements of
FCC Class B.
A Comprehensive 24Vdc to
12Vdc Converter Range
This leaflet covers the PowerVerter series, ten products
from 3 Amps to 30 Amps 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 agricultural vehicles,
commercial vessels,
yachts and many types

PV PowerVerter 24Vdc to 12Vdc converter
3 3 amps continuous output
(12Vdc output at 3 amps)
i Isolated between input and output
(s indicates switchmode, non-isolated)
proportional to temperature so
high efficiency leads to high
reliability. The Mean Time
Between Failure figure is around
160 years!
Rugged and Compact
The converters are enclosed in a
rugged aluminum extrusion. The
low mass Surface Mount Technology
components are also less prone to
damage from vibration and shock,
further increasing the reliability of
the units. The use of SMT results in
a very compact unit, making it
easier for the installer to find a
convenient location.
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.
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.
The low heat dissipation allows them to be
mounted in less well ventilated positions which
makes installation easier.
All the 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.
