12V DC - 12V DC Isolated 6/8A Converter
12V-12V, 24V-24V, 12V-24V and 48V-12V Converters for a wide range of applications
If you need to fit 24V equipment onto a 12V vehicle, then an up converter from the DD Series offers a fast and easy way to configure your system. Or, if you need to stabilise your voltage or isolate your supply, then the DDi Series of 12V-12V and 24V-24V Isolators will suffice. There are also 48V-12V units available for telecoms and forklift truck applications.
These 12V units are ideal for small vehicle applications such as cars, minibuses, small marine craft, caravans and motorhomes and a variety of industrial uses.
12V-12V and 24V-24V units provide a stable output voltage as well as providing galvanic isolation for a variety of application.
A Wide Product Range
There are three 12V-24V products in the range running at currents from 3A (DD 12-24 072) to 10A (DD 12-24 240), while there are 5 more products from 3A – 10A in the 12V-12V and 24V-24V isolator range. All products use modern switchmode designs and are built using the same manufacturing concepts and technologies as the successful PowerVerter range which will of course meet your 24V-12V requirements.
Fast Installation
All the units consume an off load current of less than 100mA, which is probably less than the self discharge current of the vehicle’s battery. 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, 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.
The 12V-24V converters have been used for a variety of applications including bus ticketing systems on mini buses and for 24V bow thrusters on leisure craft.
