Dolphin 12/24V 30A DC-DC Battery Converter

Description

The Dolphin 12/24V 30A DC-DC Battery Converter provides controlled charging from a 12V alternator or starting battery system to a separate 24V service bank. It is useful for boats with 24V trolling motors, bow thrusters, or auxiliary loads that need charging while the engine is running.

Unlike a basic voltage converter, the Dolphin BOOSTER platform uses a smart multi-stage charging program and supports lead-acid, Gel, AGM, and lithium battery technologies. This helps the auxiliary bank receive a more complete and controlled charge while also reducing dependence on shore power between trips.

Built-in protection covers source-battery drainage, over-current, over-voltage, reverse polarity, and fuse faults. The compact high-frequency design saves installation space, while conformal coating on the circuit board improves resistance to the marine environment. For vessels that need to charge a 24V auxiliary bank from a 12V engine electrical system, this 30A DC-DC charger provides a purpose-built underway charging solution. Worth comparing against our other DC-DC battery chargers.
