The Orion-Tr Smart isolated DC-DC charger serves as a DC-DC battery charger or as a power source (it is also designed for use as a constant voltage source) and offers a wide input and output voltage range. This is particularly important for vehicles with a Euro 5 or Euro 6 intelligent alternator, which often delivers too low a charging voltage even when the engine is running, or when longer cables, as is often the case with boats and motorhomes, lead to voltage drops. In such scenarios, precise and controlled charging is essential to fully charge the service battery and protect the starter/input battery from discharge
