Protect Your Vessel from Galvanic Corrosion with a 4500W Marine Isolation Transformer

The Victron Isolation Transformer 4500W 115/230V provides complete electrical isolation between shore power and your vessel, improving onboard safety while helping prevent galvanic corrosion. By separating the shore-side electrical earth from the boat's electrical system, it eliminates electrical continuity that can damage underwater metal components such as shafts, propellers and sacrificial anodes. The transformer also maintains proper grounding on the secondary side, allowing onboard protection devices to operate correctly. Featuring a toroidal transformer design, integrated input circuit breaker and soft-start technology, it is suitable for marine electrical systems operating on either 115V or 230V AC shore power.

Key Features

• 4500W Continuous Capacity: Supports onboard AC systems with a current rating of 38A at 115V or 19A at 230V.
• Electrical Isolation from Shore Power: Eliminates electrical continuity between shore power and the vessel to improve electrical safety.
• Helps Prevent Galvanic Corrosion: Protects submerged metal components including propellers, shafts and sacrificial anodes from galvanic corrosion caused by shore grounding.
• 115V or 230V Operation: Can be configured for 115V or 230V input and output, making it suitable for a wide range of shore power systems.
• Multiple Voltage Configurations: Supports 115V-to-115V, 230V-to-230V, 115V-to-230V and 230V-to-115V transformer configurations.
• Integrated Soft-Start Function: Reduces transformer inrush current during connection to help prevent nuisance tripping of shore power circuit breakers.
• Toroidal Transformer Design: Provides quiet operation while reducing weight and improving efficiency compared with conventional transformer designs.
• Integrated Input Circuit Breaker: Includes built-in input protection for safer installation and operation.
• Marine Aluminium Enclosure: Durable aluminium housing with an IP21 protection rating for marine electrical installations.
• Maintains Onboard Electrical Protection: Allows onboard GFCIs and circuit protection devices to function correctly by providing an isolated secondary supply.

The Victron Isolation Transformer 4500W provides an effective solution for improving onboard electrical safety while reducing the risk of galvanic corrosion. Its flexible voltage configuration makes it suitable for vessels operating with either 115V or 230V shore power connections.
