Marine Isolation Transformers Energy Solutions offer single and three phase Isolation Transformers of all capacities. Our standard range of Isolation Transformers have the following features. Complete range. Our standard transformer range covers 10, 16, 32, 50, 63 & 100 amp single phase shore capacities at 230v. Voltage conversion models. We offer a 63 amp transformer that selects between two input tappings with 208 volt and 240 nominals - ideal for USA spec boats looking for an alternative to the Charles Industries Iso-Boost. Dedicated output. Our larger transformers come configured to provide either 120 - 0 - 120v 4 wire USA output or 0 - 230v 3 wire Euro output. ABYC compliant. All transformers are built with a screen between primary and secondary windings capable of carrying twice the full load current of the transformer. This exceeds the requirements of ABYC E-8.20.1 by 100%. Lloyds compliant. All transformers are built to comply with the requirements of LRS. Resin coated. The transformers are protected with a UL approved vacuum impregnated polyester varnish. Marine Isolation Transformers

Background Bringing shorepower onto a yacht or ship offers a great deal of convenience for the owner. But it can also lead to galvanic corrosion and other problems. Good engineering practice, Lloyds rules and the Recreational Craft Directive all call for an on-board AC earth system to be bonded through to the sea. On a metal-hulled boat this is done by taking the earth to the hull, on other craft it is via a specific ‘grounding’ plate. In making this important safety connection you create a galvanic loop which can accelerate corrosion of the boat. To understand how this problem is created...

Output voltage options The standard output offering suits both European and USA specification boats. For European 3 wire boats only the 230-volt take off are used. For American spec boats the centre tap turns the output onto a 120 - 0 - 120 volt 4 wire specification. Because the transformer determines the output configuration of the power to the yacht it can ‘convert’ a floating supply, as seen in most European countries, to a neutral earth bonded system. It therefore eliminates the need for double pole circuit breakers and switches and eliminates the problems of reverse polarity. Single...
