Shore Power Converter 40-300 kVA

Borri SCB is a compact and robust shore power converter designed for marine applications. The system relies on Borri great expertise in industrial power protection solutions.

The converter can be connected to the most used AC supply sources thanks to its extremely wide input voltage and frequency range. It works in double conversion using state-of-the-art IGBT technology with DSP controls. This allows to minimize the input harmonics and to obtain the best output performance.
The overall efficiency is optimized thanks to the Borri patented Green Conversion technology.
The dual input configuration can be achieved using two independent converters connected in parallel with the Borri advanced parallel control.

Borri power converters are built to fit in the narrowest spaces of super, mega and giga yachts, providing highly reliable power at different voltages and frequencies.
