DESCRIPTION
Victron 3600W Isolation Transformer: Marine-Grade Galvanic Corrosion Prevention with Auto-Sensing Voltage
Engineered Safety for Onboard AC Systems
The Victron 3600W Isolation Transformer provides a critical safety barrier between shore power and your vessel's electrical system. By completely isolating the boat from the shore ground, it eliminates the risk of galvanic corrosion that can silently destroy propellers, shafts, and through-hull fittings. This is not just a convenience; it is a fundamental protection for any boat connected to AC shore power.
Unlike galvanic isolators that only partially block low-voltage DC currents, a full isolation transformer breaks the electrical continuity entirely. This ensures that your sacrificial anodes are not rapidly consumed and that your underwater metals remain intact, even in marinas with poor shore-power grounding.
Auto-Sensing 115/230V Input for Global Cruising
This model automatically detects the incoming shore voltage and configures itself accordingly. When connected to a supply between 88V and 130V, it switches to 115V mode; for supplies between 185V and 250V, it engages 230V mode. This auto-sensing capability makes it ideal for vessels that travel between regions with different shore power standards, eliminating manual switching and reducing the risk of equipment damage.
The transformer also provides a slight voltage boost with its 1:1.05 ratio, compensating for voltage drop in long shore-power cables and ensuring your onboard appliances receive a stable supply.
Soft Start Technology Protects Shore Power Breakers
Large transformers can draw a significant inrush current when first energised, often tripping marina breakers. The integrated soft start circuit in this Victron unit limits that initial surge, allowing a smooth connection every time. This feature is especially valuable in older marinas with sensitive breakers, preventing frustrating power interruptions.
Built for the Marine Environment
Housed in a robust aluminium enclosure with a corrosion-resistant blue finish (RAL 5012), this transformer is rated IP21 for protection against dripping water. The toroidal core design minimises audible hum and reduces weight compared to traditional laminated transformers, making installation easier in tight engine rooms or lazarettes. Recessed handles on the sides allow for safe lifting and positioning of the 21.7 kg unit.
Bottom-entry compression glands provide secure, strain-relieved cable connections, maintaining the integrity of the wiring even in high-vibration marine environments.
Key Features
- Complete galvanic isolation eliminates shore-power ground connection, preventing corrosion
- Automatic 115/230V input detection for worldwide compatibility
- Soft start circuit prevents nuisance tripping of shore breakers
- Toroidal transformer design for low noise and reduced weight
- 1:1.05 voltage ratio compensates for cable voltage drop
- Robust IP21 aluminium enclosure with recessed handles
- 32A output at 115V, 16A at 230V for versatile load handling
Applications Beyond Basic Isolation
While primarily designed for marine use, this transformer is also suitable for industrial and mobile applications where galvanic isolation is required. It can be configured as a step-up or step-down transformer: 115V to 120V, 230V to 240V, 115V to 240V, or 230V to 120V. This flexibility makes it a valuable component in custom power systems for workshops, remote sites, or specialised equipment.
For optimal safety, it is recommended to connect the secondary neutral to ground when the vessel is out of the water, ensuring full GFCI functionality during maintenance.

WARRANTY
Victron Energy Limited Warranty Policy
Direct Customers
Victron Energy provides the following warranty to any direct customer (OEM, distributor or dealer) in relation to any products that Victron Energy has directly sold to the direct customer. This warranty is not an end-user warranty between Victron Energy and an end-user, and end-users shall not have any rights or remedies under this limited warranty towards Victron Energy directly. The direct customer shall, in turn, ensure that the end-user is provided with a warranty identical to this warranty, subject to applicable local mandatory law.
End-Users
Victron Energy may also provide a warranty directly to end-users, in which case the below warranty conditions equally apply to such warranty. In that case, end-users shall claim their warranty at their place of purchase or through the original direct customer of Victron, which can be found through the support section on Victron’s website. Hence, the direct customer shall on behalf of Victron Energy deal with any warranty claims made under any warranty that Victron Energy may provide directly to end-users.
