Victron Buck-Boost DC-DC Converter

Victron Battery to Battery Chargers

DC-DC converter for charging a 12V or 24V battery in vehicles with a smart alternator
Particularly suitable for regenerative braking, Euro 5 and Euro 6 engines.
The DC-DC Buck-Boost converter is a DC-DC converter for charging a 12V or 24V battery in vehicles with a smart alternator. The converter charges the auxiliary battery with a preset charging voltage, eliminating high voltages (e.g., Mercedes: 15.4V) and low voltages.

Charging booster for travel vehicles
The Buck-Boosters ensure fast and efficient charging of the leisure battery from the alternator while driving. Unlike simple battery isolators, the charging voltage is raised to the value required for a full charge for the respective battery type and demanded by battery manufacturers. This allows the full charging current to flow, and significant amounts of power can be charged into the battery in a short time. Long charging cables and losses, as well as voltage fluctuations at the alternator, are cleanly regulated.
The free programmability allows the device to boost the voltage (from 12V to 24V), buck the voltage (24V to 12V), or only adjust it to the appropriate charging voltage (12/12V or 24/24V systems)

"Engine running" state detection system
Deep discharge of the vehicle's starter battery is prevented by a built-in system that detects when the "engine is running". Instead of this detection system, the converter can also be activated by a programmable input (D+, CANbus, or (+)15 terminal).

Fully programmable
The converter can be fully programmed using a simple and user-friendly PC application. (A USB Type A to USB Type B cable is required)

A product for 12V, 24V, and 12/24V systems
The converter can be programmed to charge a 12V or 24V auxiliary battery via either a 12V or 24V alternator or a starter battery.

Input current limiting
The output current is determined by the following factors:

• The setting of the maximum charging current.
• The setting of the maximum input current.
• The limitation of the converter's maximum operating temperature.
