Victron Energy – 50A Buck-Boost DC/DC Converter

50A 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.

‘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 the threshold, converter off.

Red: over temperature, converter off.

Blue, quick flash: engine running, the converter will start after a 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.
