SP200 Shore Power Converter

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 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

Grain-orientated 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 power output

The output module delivers a clean, stable supply suitable for all types of onboard loads, from utility services (heating, lighting and air conditioning) to entertainment (television and audio) to marine (winch, pumps and navigational equipment).

Continuous clean output power

The output converter delivers a stable and clean waveform for powering onboard equipment. Loads range from utility services (heating, lighting and air conditioning) to 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 onboard control and automation sections to facilitate installation.

Unique modular design

The modular design makes the system compact and highly serviceable. In the unlikely event of a module failure, 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.

I have been employed as a Chief Engineer on 65-90 metre motor yachts for over 10 years. During this period I have operated most of the market leader shore power convertors of which I have found some to be good and some to be truly terrible.

My experience with Kibo’s Magnus shore power convertor over the last 12 months - during which period she has been connected to shore power for over 7 months, has been very positive. The installation, operation and reliability of the unit has been excellent and all visiting service technicians have been helpful and knowledgeable. I have also found Magnus’s support and aftersales second to none with technical enquiries answered promptly regardless of the hour or day of the week.

I believe where Magnus truly excels is the quality of their products, which have been developed with the ease of operation, rapid diagnostic identification and future upgradability all at the forefront of their design, which to a busy yacht engineer is paramount. Magnus shore power convertors are pretty much a fit and forget appliance and it is reassuring to know that the shore power will be constant and reliable for extended periods alongside.

I have no hesitation in recommending Matthew Scales at Magnus and I will ensure that all future new builds that I am involved in are installed with their equipment.
