Product Description


    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 and low voltages.

    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).

    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)

    The converter can be programmed to charge a 12 V or a 24 V auxiliary battery from either a 12V or a 24V alternator and starter battery.

      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 preset 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.
