Buck-Boost DC-DC Converter 25A / 50A / 100A
Victron Energy Buck-Boost DC-DC is a programmable converter designed to charge 12 V or 24 V service batteries in vehicles equipped with smart alternators. It provides controlled battery charging even when alternator voltage varies while the engine is running.
Description
The Buck-Boost DC-DC Converter is particularly suitable for modern vehicles with smart alternators, including Euro 5 and Euro 6 systems. These alternators can vary their output voltage depending on operating conditions, making reliable direct charging of an auxiliary battery difficult.
The converter supports an input and output voltage range of 10–30 V and can be configured to charge either a 12 V or 24 V auxiliary battery from a 12 V or 24 V vehicle electrical system.
An integrated engine-running detection system helps protect the starter battery against excessive discharge. The converter can also be activated through a programmable input such as D+, CAN bus or an ignition signal, depending on the model.
Operating parameters can be configured through a PC application, including charge voltage, maximum charging current and input-current limits.
The range is available in 25 A, 50 A and 100 A versions.
