Collection: Isolation Transformers / Autotransformer / Galvanic Isolator

RV isolation transformers and galvanic isolators protect your electrical system when you plug into shore power at a campground or marina. This collection includes the Victron Galvanic Isolator VDI for split-phase installations, the Victron Autotransformer with automatic input voltage detection, and the Victron Isolation Transformer, all built for RVs, campers, and off-grid setups running on 120V or split-phase shore power.

A galvanic isolator blocks stray DC current that causes corrosion on your hull or chassis ground, an isolation transformer fully separates your onboard AC system from the shore connection, and an autotransformer balances a split-phase pedestal automatically, so match the unit to your amperage and voltage setup before wiring it in.
