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.

‘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
