Automatic Phase Correction

SmartPhase is a fully automatic phase changer for use when an external power supply is to be used that may have a different phase rotation to the internal supply. For example, ocean going ships require a constant power source even when in port. Emergency equipment, refrigeration, cooling, heating, lighting and other equipment can be powered from an on-shore electrical source at a berth, allowing on-board engines to be shut down.

If the shore-power has a phase rotation that is different to the on-board generator and it is connected without checking then there will be a problem with equipment not operating correctly with a chance of causing a serious problem. The solution is to rewire the shore-power so that the phase rotation is the same as the on-board generator. This can be inconvenient, difficult and sometimes a hazardous operation.

SmartPhase automatically connects the shore-power to the boat correctly every time.

Key features include:

• Automatically corrects the phase rotation and connects the shore-power.
• Rugged, reliable and efficient giving a long service life with minimal maintenance.
• The control stores the phase rotation of the on-board generator so it does not have to be running to connect the shore-power correctly.
• The connection is made using carefully controlled AC3-rated contactors.
• If the shore-power fails SmartPhase will disconnect and when it is reinstated and is stable for a preset period it will correct the phase rotation and reconnect.
• Steel enclosure, IP66 ingress protection.
• Colour RAL7035
