By eliminating 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 safety equipment such as GFCIs and circuit breakers.\u003c\/p\u003e\n\n\u003cp\u003eThis automatic model detects the incoming shore power voltage and switches between the \u003cstrong\u003e115V and 230V input ranges\u003c\/strong\u003e without requiring manual input reconfiguration. This makes it particularly suitable for vessels travelling internationally or connecting to marinas with different shore power standards.\u003c\/p\u003e\n\n\u003ch3\u003eAutomatic 115V and 230V Input Detection\u003c\/h3\u003e\n\n\u003cp\u003eThe transformer automatically selects the appropriate input range based on the incoming shore power voltage:\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e88V to 130V input:\u003c\/strong\u003e automatically selects the 115V input range\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e185V to 250V input:\u003c\/strong\u003e automatically selects the 230V input range\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eThis automatic switching removes the need to manually reconfigure the transformer when connecting to a different shore power voltage. The AC output can be configured for either \u003cstrong\u003e120V or 240V\u003c\/strong\u003e to suit the vessel's onboard electrical system.\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 Voltage Conversion\u003c\/h3\u003e\n\n\u003cp\u003eIn addition to electrical isolation, the transformer can support different input and output voltage combinations:\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 powering a 240V onboard system from a 115V shore supply\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e230V to 120V\u003c\/strong\u003e for powering a 120V onboard system from 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.

This helps compensate for voltage drops commonly experienced across long shore power cables and marina electrical infrastructure. A nominal 115V input provides approximately 120V output, while a nominal 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 for demanding onboard AC systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutomatic 115\/230V input detection\u003c\/strong\u003e for use with different shore power supplies\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e120V or 240V output options\u003c\/strong\u003e for isolation or voltage conversion\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGalvanic isolation\u003c\/strong\u003e between shore power and the vessel's electrical system\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSoft-start technology\u003c\/strong\u003e to reduce 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 operating noise\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 for Reliable Shore Power Connection\u003c\/h3\u003e\n\n\u003cp\u003eHigh-power transformers can draw significant inrush current when first connected to shore power.
