Highly efficient voltage converter with additional output connection – safe, constant, shock- resistant

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.

The IVT switch mode voltage transformers were developed to provide a higher 24 V voltage system into a lower 12 V system. The highly efficient electronics guarantee a trouble-free and safe operation of 12 V DC devices.

The 18 A DC/DC voltage converter also has a second, switchable 12 V DC output.

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-certification.

Important characteristics and features

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.

Two 12 V outputs – one of them switchable

The second 12 V output is only active when the vehicle's ignition is on.

The additional switchable 12 V DC output can be used in a vehicle, for example, to ensure that the loads connected here are only active when the engine is running. Unnecessary power consumption and a load on the starter battery can thus be avoided.

Shock-resistant

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 to EN 60068-2-6/14/64/27.

Very high efficiency – minimum own power consumption

Due to the efficient technical design, the efficiency of the 18 A version is > 87 % and the stand by current can be reduced to a minimum of 0.2 mA. Furthermore, this converter is characterised by its low heating.

Robust and compact design

Thanks to the clever design, the converter is particularly compact. The robust aluminium housing also offers optimal protection against impacts as well as damage from the outside. Stable mounting is possible thanks to the holes integrated in the base 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.

E-certification – suitable for permanent installation in the vehicle

Thanks to the E-certification, 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.

Application in 24 V off-grid solar systems

Even with an existing 24 V off-grid solar 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.

3 year manufacturer warranty

IVT products are manufactured to a high quality and following strict quality guidelines. We are certain about the longevity so that we add another year to the statutory manufacturer warranty free of charge. Rechargeable batteries and batteries are excluded from this warranty.
