DC/DC Voltage Converter IVT 24 V/12 V, 20 A


Recommended use:



Highly efficient. Robust. Safe.


The number of electronic devices used in vehicles is steadily increasing. These are generally designed for 12 V, e.g. Entertainment electronics, navigation systems, cooling boxes and much more. In order to be able to operate these 12 V loads also in board systems with 24 V, the use of a DC / DC voltage converter is mandatory.


IVT switch mode voltage transformers were developed to provide a  24 V Voltage system into a 12 V-System. The highly efficient electronics guarantee a trouble-free and safe operation of 12 V DC devices. All IVT converters are shock-resistant and characterized by high efficiency, low power loss, stable output voltage and a particularly compact and robust design.


Recommended use:

Ideal for permanent use in construction machines, trucks, travel coaches, forklift trucks, in agricultural and forestry vehicles, motor boats and sailing boats, as well as for camping and mobile homes, also in connection with 24 V solar systems or wind power.


Efficient voltage converters for demanding applications -
Safe, constant, shock resistant.


The switch mode IVT voltage converters were developed  to convert an input DC voltage of 24 V into a stable 12 V DC output voltage. The highly efficient electronics guarantee, that there are hardly any losses during voltage conversion.

All IVT converters are shock-resistant. The encapsulated electronics as well as the robust metal housing guarantee a long-term use under the harshest conditions. All current protective circuits are integrated as standard. The fixed installation in vehicles with road approval is permitted due to the E-approval.


The most important characteristics and features:

  • E1-approval

Stable and constant output voltage:

Input voltage range from 18 V DC to 32 V DC, the IVT voltage converter reliably delivers a stabilized and constant output voltage of 13.8 V.This output voltage can be used as a power supply for various 12 V consumers, e.g. Entertainment electronics, navigation systems or cooling boxes.


Switchable 12 V DC output:

By means of the additional switchable 12 V DC output, it is ensured, for example, in a vehicle that the loads connected here are active only when the engine is running. Thus, unnecessary power consumption and a load on the starter battery can be avoided.



The encapsulated electronics guarantee long-term operation under the most adverse conditions. Even with constant shocks and vibrations, e.g. in large construction machines, the voltage transformer works absolutely reliably and safely. The DC / DC voltage transformer has been tested by an official body according to EN 60068-2-6 / 14/64/27.


Robust and compact metal housing:

Thanks to the ingenious design, the converter is particularly compact. The robust aluminum housing also provides optimum protection against impacts and damage from the outside. Stable mounting is possible thanks to the holes in the bottom plate.


Standard protection circuits:

This voltage converter is equipped with all common protection circuits naturally integrated as standard. The device is protected against polarity reversal Short circuit protected at input and output. In case of an overload, the Output voltage is automatically reset at constant current. Should nevertheless the vehicle fuse is triggered, it can be exchanged quickly and easily in case of need.


Application in 24 V Solar off-grid systems:
Even with an existing 24 V solar off-grid system, the use of an IVT voltage transformer is recommended to reduce the voltage to 12 V. This means that existing or inexpensive 12 V devices can be used without any problems.


Thanks to the E-approval, this converter is suitable for permanent installation in a wide range of vehicles with 24 V vehicle voltage. The scope of application therefore ranges from construction site vehicles, forklift trucks, touring busses, snowmobiles to trucks and motor homes and boats.
