By removing electrical continuity between the shore-side supply and the vessel, it helps prevent \u003cstrong\u003egalvanic corrosion\u003c\/strong\u003e while supporting the correct operation of essential safety equipment such as GFCIs and circuit breakers.\u003c\/p\u003e\n\n\u003cp\u003eDesigned for use with \u003cstrong\u003e115V or 230V AC input\u003c\/strong\u003e, the transformer can be configured during installation to provide either \u003cstrong\u003e120V or 240V AC output\u003c\/strong\u003e. This allows it to provide electrical isolation or voltage conversion for vessels operating with different shore power and onboard voltage systems.\u003c\/p\u003e\n\n\u003ch3\u003eWhy Galvanic Isolation Matters\u003c\/h3\u003e\n\n\u003cp\u003eConnecting a vessel directly to shore power can create an electrical path between the shore earth and underwater metal components such as propellers, shafts and through-hull fittings. This can accelerate galvanic corrosion, rapidly deplete sacrificial anodes and cause premature damage to valuable underwater equipment.\u003c\/p\u003e\n\n\u003cp\u003eThe Victron Isolation Transformer prevents this by transferring power magnetically between separate primary and secondary windings. Shore power is connected to the primary side, while the vessel's electrical system is supplied from the secondary side, electrically isolating the vessel from the shore earth.\u003c\/p\u003e\n\n\u003cp\u003eThis protection is important for fibreglass vessels as well as aluminium and steel hulls, as galvanic corrosion can occur whenever electrically connected metal components are exposed to water.\u003c\/p\u003e\n\n\u003ch3\u003eFlexible 115V and 230V Configuration\u003c\/h3\u003e\n\n\u003cp\u003eThe transformer can be configured for different input and output voltages using the supplied jumper wires. The required voltage configuration must be selected during installation before power is applied.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e115V to 120V\u003c\/strong\u003e for isolation within a nominal 115V system\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e230V to 240V\u003c\/strong\u003e for isolation within a nominal 230V system\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e115V to 240V\u003c\/strong\u003e for stepping up a 115V shore supply\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e230V to 120V\u003c\/strong\u003e for stepping down a 230V shore supply\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eThe transformer supports both \u003cstrong\u003e50Hz and 60Hz AC systems\u003c\/strong\u003e. It does not convert frequency, so the output frequency remains the same as the input frequency.\u003c\/p\u003e\n\n\u003ch3\u003e5% Voltage Boost\u003c\/h3\u003e\n\n\u003cp\u003eThe transformer's \u003cstrong\u003e1:1.05 winding ratio\u003c\/strong\u003e increases the output voltage by approximately 5%. This helps compensate for voltage drops commonly experienced across long shore power cables and marina electrical infrastructure. A 115V input provides approximately 120V output, while a 230V input provides approximately 240V output.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e4500W power rating\u003c\/strong\u003e with output current ratings of 38A at 115V and 19A at 230V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGalvanic isolation\u003c\/strong\u003e between shore power and the vessel's onboard electrical system\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfigurable 115V or 230V input\u003c\/strong\u003e for different shore power supplies\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfigurable 120V or 240V output\u003c\/strong\u003e for isolation or voltage conversion\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSoft-start technology\u003c\/strong\u003e to reduce transformer inrush current and help prevent upstream circuit breakers from tripping\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1:1.05 transformer ratio\u003c\/strong\u003e to compensate for common shore power voltage drops\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToroidal transformer design\u003c\/strong\u003e for reduced weight and low noise\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature-controlled fan cooling\u003c\/strong\u003e for reliable thermal management\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOvertemperature protection\u003c\/strong\u003e that switches the transformer off if overheating occurs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAluminium enclosure\u003c\/strong\u003e finished in Victron blue RAL 5012\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eIP21 protection rating\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eEN 60076 safety compliance\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSoft Start and Temperature Protection\u003c\/h3\u003e\n\n\u003cp\u003eHigh-power transformers can draw significant inrush current when first connected to shore power. The integrated soft-start system limits this initial current, helping prevent the upstream shore-side circuit breaker from tripping when the transformer is switched on.\u003c\/p\u003e\n\n\u003cp\u003eThe transformer is also equipped with temperature-controlled fan cooling. Fan speed increases as the internal temperature rises, while built-in overtemperature protection switches the transformer off if unsafe operating temperatures are detected.\u003c\/p\u003e\n\n\u003ch3\u003eCorrect Operation of Onboard Safety Devices\u003c\/h3\u003e\n\n\u003cp\u003eA GFCI must be installed on the AC output of the isolation transformer. For correct GFCI operation, the AC output neutral must be connected to the AC output earth and the vessel's grounding system using the supplied neutral-to-earth jumper.\u003c\/p\u003e\n\n\u003cp\u003eWhen the vessel is out of the water for maintenance or winter storage, the vessel earth conductor must be connected directly to the shore power earth conductor. The transformer includes a dedicated connection and supplied jumper wire for this purpose.\u003c\/p\u003e\n\n\u003ch3\u003eDurable and Installation-Friendly Design\u003c\/h3\u003e\n\n\u003cp\u003eThe transformer is housed in a durable aluminium enclosure with an \u003cstrong\u003eIP21 protection rating\u003c\/strong\u003e.

At least 100mm of clear space should be maintained around the transformer for ventilation, and the cooling fan openings must remain unobstructed.\u003c\/p\u003e\n\n\u003ch3\u003eProfessional Installation Required\u003c\/h3\u003e\n\n\u003cp\u003eThe Victron 4500W Isolation Transformer is a Safety Class I electrical product and must be installed by a suitably qualified person. Input and output voltage configurations, cable sizes, protective earthing, GFCI protection and circuit breakers must comply with the installation manual and applicable local electrical regulations.\u003c\/p\u003e\n\n\u003ch3\u003eProtect Your Vessel and Onboard Electrical System\u003c\/h3\u003e\n\n\u003cp\u003eSuitable for cruising yachts, motorboats and commercial marine installations, the Victron 4500W Isolation Transformer combines galvanic isolation, voltage conversion and electrical safety in one robust unit.
