SP200 Yacht Shore Power Converter

Maximises power availability

Using the latest modular design, the SP200 provides a highly reliable, clean and efficient shore power conversion system. Active front-end technology on each shore cord input enables maximum power transfer to the yacht. Drawing clean sinusoidal module redundancy current at Unity Power Factor from any power source not only ensures minimum supply disturbances but increases power availability to its maximum. Multiple input converters can be connected to any supply available.

Protection from shore supply

High-grade transformers, connected directly to the shore cord, guarantee galvanic isolation at the lowest possible weight. No common-mode RFI can reach the shore supply and there is no path for any currents which may be sensitive to the shore supply breaker.

Continuous clean output power

The system output delivers a stable and clean waveform for powering on-board equipment. Loads range from utility services (heating, lighting and air conditioning) and entertainment (television and audio) to marine (winch, pumps and navigational equipment).

Built-in synchronisation

Built-in synchronisation allows for seamless transfer from shore to generator and vice versa. In addition, automatic synchronisation allows the SP200 converters to start on a live bus, minimising on board control and automation.

Unique modular design

The modular design makes the system compact and highly serviceable. In the unlikely event of module damage, the system will continue to operate at a reduced capacity. Modules can be isolated and replaced with minimal downtime. On replacement, each module will automatically be configured ready for service.
