The Buck-Boost DC-DC Converter is designed for charging a 12V or 24V service battery in vehicles equipped with a smart alternator, including those with regenerative braking, Euro 5, and Euro 6 engines. The converter ensures the auxiliary battery is charged with a pre-set charge voltage, eliminating the issues of high and low voltages. It features an 'engine running' detection system to prevent deep discharge of the vehicle's starting battery. The converter can also be activated through a programmable input, such as D+, CAN bus, or (+)15 connection. It is fully programmable via a user-friendly PC application.
