PowerVerter

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.


PowerVerter 24Vdc to 12Vdc Voltage Converters

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 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 PowerVerters are enclosed in a rugged aluminium 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.

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 green LED indicates when there is output from the converter. This gives reassurance to the installation enginer 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 PowerVerter 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.
