The sensitivities of modern electronic equipment to variable input voltages susceptibility to EMC interference and in some cases the need to isolate the supply has made voltage stabilisation an important section of our product range. Start/Stop technology on motor vehicles has added to this problem. The DDi Series offers a wide range of 12V-12V and 24V-24V isolated products that ensure a stable and reliable voltage can be delivered to important equipment even when the electrical system is under duress such as during engine cranking. Units are available from 36-240W. The range now also offers 48V-12V units suitable for the telecoms and forklift truck markets. For 12V-24V converters see DD Series \'Up\' Voltage Converters

A Comprehensive Product Range

There are three products in the 12V-12V isolator range from 36W to 108W and a further four products in the 24V-24V range from 72W to 240W. There are also three 48V-12V products from 36W to 108W. All products use modern switchmode designs and are built using the same 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 15mA 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 onto uneven surfaces. It is easy to fit the clip into awkward places then simply click the unit into position. The green LED indicates when there is output from the converter. This gives reassurance to the installation engineer and speeds fault finding.
