Description

Overview

The Victron Buck-Boost DC-DC Converter is designed to reliably charge a 12V or 24V service battery in vehicles equipped with intelligent dynamos. In modern Euro 5 and Euro 6 vehicles, alternator output is dynamically controlled by onboard electronics, often resulting in insufficient or inconsistent charging voltage for auxiliary batteries.

By actively boosting or reducing the input voltage as required, the Buck-Boost DC-DC Converter ensures the service battery receives the correct charging voltage whenever the engine is running. This makes it an essential component in dual battery vehicle systems where dependable charging performance is critical.
