Victron Isolation Transformer 3600W Auto 115/230V

The Isolation Transformer: A Must-Have for Professional Marine Energy Systems

In professional marine energy systems, the importance of an Isolation Transformer cannot be overstated. It plays a crucial role in ensuring the safety of the electrical system aboard and protecting the vessel from galvanic corrosion, a common issue that can lead to significant damage if not properly managed.

Why an Isolation Transformer is Indispensable:

• Prevents Electrolytic Corrosion: By eliminating electrical continuity between the AC shore power and the boat, the Isolation Transformer prevents galvanic corrosion. This type of corrosion occurs when two dissimilar metals are in electrical contact in an electrically conducting fluid like seawater, leading to the preferential corrosion of the more active metal.
• Ensures Electrical Safety: Without an Isolation Transformer, bringing only the live and neutral wire on board creates a risky situation where Ground Fault Circuit Interrupters (GFCIs) will not operate, nor will a fuse blow in the event of a short circuit. This compromises the safety of the vessel and its occupants.
• Soft Start Circuitry: A standard feature of Victron Energy isolation transformers, soft start circuitry prevents the shore circuit breaker from tripping when plugged in, managing the inrush current effectively.

How It Works:

• Eliminates Unsafe Ground Connections: Connecting the ground wire from the shore-side supply directly to the boat’s metal parts can lead to galvanic corrosion. The Isolation Transformer allows for a safe connection by isolating the boat from the shore ground, thereby preventing corrosion of metal parts and sacrificial anodes.
• Safety Mechanism: By connecting all metal parts aboard to the neutral output on the secondary side of the transformer, safety is significantly enhanced. In case of a short circuit, a GFCI will trip, or a fuse will blow, ensuring protection against electric shock and fire hazards.

3600 Watt Auto 115/230 V Model:

• Automatic Voltage Selection: This model can automatically switch between 115 V and 230 V supply, adapting to the input voltage. It ensures compatibility with varying shore power systems, making it versatile for international use.
• Voltage Adjustment: The AC input voltage undergoes a slight increase in the ratio of 1:1.05 at the AC output, optimizing the power supply for onboard equipment.
• Grounding for Optimal Safety: When the boat is out of water, it’s recommended to connect the secondary neutral of the transformer to the ground. This practice enhances safety by ensuring proper operation of protective devices.

The Isolation Transformer is not just a component; it’s a comprehensive solution for maintaining the integrity of a boat’s electrical system and ensuring the safety of those aboard. By isolating the vessel from potential electrical hazards and preventing the destructive effects of galvanic corrosion, it stands as an essential investment for any professional marine setup.
