SP100 Yacht Shore Power Converter

Connection to any of the common worldwide shore voltage and frequencies, single or three phases. As a result, connection can be made to shore quickly and without fuss, no matter where the yacht is berthed.

Maximisies power availability

Active front-end technology enables maximum power transfer from shore and complies with proposed marina power quality regulations. Control of the shore current prevents tripping of sensitive shore circuit breakers with both low earth leakage and transient current protection.

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).

Graphical display

A colour graphical 7” display provides a clear assessment of the system and its load. Data logging and events can be accessed locally or remotely through a network.

Marine class

Lightweight aluminium construction delivers IP44 protection against engine room dust and swarf. The converter can be bulkhead or deck mounted and can be split into multiple sections to facilitate installation.

SP100 testimonial

Thanks very much for providing our SP100 24KVA Shore Power Converter and supporting the details we needed to get all our systems working correctly. Your attention to us is very much appreciated as I am sure it must be one of the smallest units that you make. You can be sure that I will recommend your company to other captains.

On-board Virago we have an SP100 24kVA Shore Power Converter. It is used to connect to shore when in harbour and to feed a clean electrical supply when at sea. We can connect to single or 3 phase supplies useful when on world trips. The unit has been in operation for over a year and all looks good significantly reducing the run hours on our generators. The display is remotely located and easily accessible. Support has always been available.
