These products offer a convenient way to

operate mass produced 12Vdc equipment,

such as cell phones, in car entertainment

equipment, professional communication

equipment, refrigerators, televisions, etc.

from the 24Vdc mobile electrical systems

found on diesel engined vehicles and vessels

and the 28Vdc systems found on aircraft.

The PowerVerter converter series, is a sub group

of our PowerSelecter range of converters that

offer a wide range of input and output voltages

between 12Vdc and 48Vdc (see the PowerSelecter

leaflet). For voltages above 48Vdc see our

PowerMaster Converter leaflet.

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 and commercial vessels,

yachts and all types of 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

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 or/and 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.

All the PowerVerter products are CE marked, e

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 proportional

to temperature so high efficiency leads

to high reliability. The Mean Time

There are no ventilation holes to permit stray

objects, dust or water droplets to enter the

case. 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.

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.
