DC to DC Vehicle Battery Charger

3 Sizes: 25A, 50A and 100A

This DC to DC converter series is a program of specially developed for fully-controlled charging of an extra battery or a battery bank. This is necessary for vehicles with intelligent alternator control, and for general protection of the alternator in lithium systems.

Alternators of Euro 5 and 6 engines, which are controlled by the onboard electronics, often supply too low charging voltage even with the engine running. As a result, a DC to DC converter is necessary to charge the extra battery. In the case of lithium systems, the alternator must be protected against overload, resulting in overheating, which arises because the voltage control of the alternator cannot anticipate zero resistance of lithium battery systems.

To ensure that the start battery of the vehicle is always loaded with priority, this DC to DC Converter will only provide power when the engine is running. This is possible thanks to the built-in engine running detection and the related programmable time-delayed switching. This also prevents the onboard voltage of the vehicle from becoming too low. It is not necessary to intervene in the system of the vehicle, or install a separate motor run sensor. Apart from this detection, the DC to DC Converter can also be switched on with a programmable input.

It is fully programmable through a very simple and easy application. The output current has an automatic limitation that is adjustable. The automatic stop becomes active as soon as the temperature comes close to a pre-set maximum.

The output voltage is fully adjustable and is independent of the input voltage due to the automatic DC to DC control. This control also ensures that the current will never exceed the set value. Also not when the input voltage is higher than the output voltage.
