Advanced Marine Isolation Transformer Delivering Safer Shore Power System Protection

The Victron Isolation Transformer 4500W Auto 115/230V is designed to safely isolate onboard electrical systems from shore power connections while helping prevent galvanic corrosion in marine environments. Featuring automatic 115V and 230V input switching, it provides flexible compatibility with international shore power supplies without requiring manual configuration. The transformer eliminates direct electrical continuity between shore power and the vessel, improving onboard safety and protecting metal components from corrosion damage. Built with a low-noise toroidal transformer design and integrated soft-start functionality, it reduces inrush current during startup while delivering stable AC power for marine electrical systems. Its robust aluminium enclosure and integrated circuit protection make it ideal for demanding marine installations requiring dependable shore power isolation.
