It converts automatically between 115V and 230V AC supplies and provides full electrical separation between shore earth and the vessel or vehicle chassis, removing the stray current corrosion and shock risks that come with a direct earth connection.\u003c\/p\u003e\u003ch2\u003eKey features of the victron isolation transformer\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower rating\u003c\/strong\u003e, 4500W continuous, enough for onboard AC systems running several appliances at once.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAuto voltage conversion\u003c\/strong\u003e, detects and switches between 115V and 230V AC shore supplies without manual reconfiguration.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGalvanic isolation\u003c\/strong\u003e, breaks the direct link between shore earth and hull or chassis, reducing stray current corrosion.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShock protection\u003c\/strong\u003e, removes hazards caused by poorly earthed or faulty shore power pedestals.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToroidal core construction\u003c\/strong\u003e, compact build with a rated weight of 21.8 kg.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU\u003c\/strong\u003e, ITR050452042, GTIN 8719076075202.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhy isolation matters on shore power\u003c\/h2\u003e\u003cp\u003eMarina and campsite supplies are not always clean or correctly earthed. A direct link between shore earth and a hull sets up a galvanic cell with nearby metalwork underwater, speeding up corrosion of anodes, propellers and through-hull fittings. This transformer removes that path by fully isolating the shore supply from the onboard AC circuit.\u003c\/p\u003e\u003cp\u003eThe auto 115\/230V function is useful for anyone moving between UK, European and North American shore power, or wherever the incoming voltage cannot be guaranteed.

On vessels, follow the relevant edition of BS EN ISO 13297 or applicable flag state rules. It weighs 21.8 kg and needs a secure, ventilated, dry mounting location, with cable and circuit protection sized for the full 4500W load. Do not fit in bilge areas exposed to flooding or water ingress.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":52095611109664,"sku":"ITR050452042","price":421.23,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1010\/8148\/1504\/files\/ledandsolar-itr050452042-1.webp?v=1785755936","url":"https:\/\/www.ledandsolar.co.uk\/products\/victron-4500w-auto-isolation-transformer","provider":"LED \u0026 Solar","version":"1.0","type":"link"}
