Alfatronix Powerverter CONVERTOR 24V DC - 12V DC Isolated 3AThese products offer a convenient way to operate mass produced 12Vdc equipment such as cell phones, in car entertainment, professional communications, telematics equipment, refrigerators, televisions etc. from the 24Vdc mobile electrical systems found on diesel engined vehicles and vessels. There are 14 products in the range from 3A to 50A 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, forestry and agricultural vehicles, as well as commercial and leisure marine vehicles.
These units are IP53, so 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 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 fixing kit for din rail installation is also available. A green LED indicates when there is output from the converter. This gives reassurance to the installation engineer and speeds fault finding.
