Victron Energy 25A Buck-Boost DC/DC converter

DC-DC Converter for charging a 12V or 24V service battery in vehicles with a smart alternator (regenerative braking, Euro 5 and Euro 6 engines) 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.

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 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
