The Buck-Boost DC-DC Converter is a DC-DC converter for charging a 12/24V service battery in vehicles with an intelligent dynamo. Since, when the engine is running, these dynamos (powered by the on-board electronics of Euro 5 and 6 engines) do not always emit the correct charging current, a DC-DC converter is essential for charging the service battery properly.
To ensure that the start battery of the vehicle is always loaded with priority, the units of Buck-Boost series 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, install a separate motor run sensor or intervene in the CAN bus system. Apart from this detection, the Buck-Boost series equipment can also be switched on with a programmable input.
The Buck-Boost series is fully programmable through a very simple and easy PC 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 Buck-Boost 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.
DC-DC Converter for charging a 12V or 24V service battery in vehicles with a smart alternator- The Buck-Boost DC-DC Converter is a DC-DC Converter for charging a 12V or 24V service battery in vehicles with a smart alternator. The converter will charge the auxiliary battery with a pre-set charge voltage, eliminating high voltages (e.g. Mercedes: 15,4V) and low voltages.
‘Engine running’ detection system- Deep discharge of the vehicle's starting battery is avoided by a built-in ‘engine running’ detection system. Instead of this detection system, the converter can also be activated by means of a programmable input (D+, CAN bus or (+)15 connection).
Fully programmable- The converter can be fully programmed by means of a simple and user-friendly PC application. (USB type A male to USB type B male cable needed)
One product for 12V, 24V and 12/24V systems- The converter can be programmed to charge a 12V or a 24V auxiliary battery from either a 12V or a 24V alternator and starter battery.
Charge current and input current limiter- The output current is determined by the following factors: - The maximum charge current setting. - The maximum input current setting. - The maximum operating temperature limit of the converter.
Input status indication (LED)- Green: Converter on. Yellow: Input voltage below threshold, converter off. Red: Over temperature, converter off. Blue, quick flash: Engine running, converter will start after pre-set delay. Blue, slow flash: The converter is OFF and activation is blocked due to low input voltage.
Output status indication (LED)- Green: Converter off, battery voltage normal. Yellow: Converter off, battery voltage low. Red: Converter off, battery discharged or not connected. Purple: Converter on.

What is a warranty? A warranty is a voluntary promise offered by the person or business who sold the product or service to you. Once you buy the product or service, the promise becomes a right that can be enforced under the ACL. Warranties are separate from your automatic consumer guarantees. The consumer guarantees which apply regardless of any warranties suppliers sell or give to you, apply for a reasonable time depending on the nature of the goods or services. This means consumer guarantees may continue to apply after the time period for the warranty has expired.
