Mass GI Galvanic Isolators & Isolation Transformers

Protect your boat's electrical system with isolation transformers and galvanic isolators. Designed to prevent galvanic corrosion and electrical hazards, these devices ensure safe and stable power from shore connections.

Key Features:

  • Electrical Isolation: Eliminate direct electrical connection between shore power and your boat, preventing stray currents.
  • Corrosion Prevention: Protects underwater metal components from galvanic corrosion caused by differing electrical potentials.
  • Voltage Regulation: Some models offer voltage boosting to compensate for low marina power.

Whether you're cruising the coast or docked in a marina, isolation transformers and galvanic isolators provide essential protection for your vessel's electrical system. Whilst an isolation transformer offers the ultimate protection, galvanic isolators (also known as a zinc saver) are a very affordable, easy to install and effective alternative.
