Victron Buck boost:

 

The Buck-Boost DC-DC Converter is a DC-DC charger 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.

 

 

Features:

 

‘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 discharged or not connected. Purple: converter on.
