Vehicle Voltage Converter

View Product Range

Vehicle onboard electrical equipment may operate at different voltage levels to the vehicle battery voltage requiring use of a voltage converter.

24 volts Vehicle power to 12 v equipment

HGV truck & bus commercial vehicle (CV) electrical systems operating at between 24v and 28 volts are a typical example.
Fitment of 12v car radio or two way communications transceiver (CB radio) may be desired.
A common (undesirable) method used to wire in 12v equipment to a 24v supply can involve running a long cable from one of the series wired 12v batteries, along the chassis & into the vehicle cab often with the potential to imbalance and discharge the truck batteries leaving the vehicle unable to be started or the cable becoming damaged when the truck cab is tilted.

Professional installation uses a voltage converter (or "Voltage Dropper ") fitted inside the cab of the truck to reduce voltage of the normal 24v supply input to achieve suitable 12 volts output for the audio equipment.

12v to 24v step up converter

> Step Up Voltage Converter units are available which can raise a vehicle's 12 volt power supply to enable use of 24 volt auxiliary equipment such as nightheaters

Mains Transformer AC rectified to DC

Mains Power for Vehicle , Low Voltage Applications

Power transformers are available to reduce voltage of mains electricity supplies to operate 12v or 24 volt systems.

The typical example is a commercial vehicle used for multi drop distribution.
During delivery operation the vehicle alternator recharges the auxilliary battery bank used for tail lift operation as the vehicle travels between delivery sites.
However, whilst the vehicle is being loaded the tail lift may be in constant use with the vehicle engine off , causing the auxilliary batteries to become discharged resulting in slow operation of the tail lift equipment, and the chance that the engine may not be started.

A solution to this problem is to use a special mains powered transformer that reduces the mains voltage level and current type to enable battery support or stand alone operation of the tail lift equipment without the vehicle engine running, avoiding the safety issue of engine operation on unattended vehicles.

DC -DC Converter

Direct current input to direct current output voltage converter may be used with solar panel photovoltaic (PV) systems , hydro electric, or wind power systems.

DC-DC converters are also found on electric vehicles to enable 12v battery charging from the high voltage battery pack.

Alternator Voltage Regulator

DC input from rectifier pack diodes regulated to provide controlled DC output voltage for battery charging.

Dynamo Current Voltage Regulator
