When connecting your yacht to shore power, it’s important to understand the difference between a shore power converter and an isolation transformer—and whether you need one, the other, or both.

Shore power converters do more than adapt the connection. They:
✅ Convert voltage to match your onboard system.
✅ Convert frequency (e.g., from 50Hz to 60Hz).
✅ Adapt phase (single-phase or three-phase).
✅ Provide electrical isolation for safety.

In contrast, an isolation transformer only isolates the shore ground from your boat’s ground. This prevents stray currents and corrosion but does not convert voltage or frequency.

Which should you choose?

• If you travel internationally or dock at marinas with different voltages and frequencies, a shore power converter like ANG Shore Power Converters™ is essential.
• If you always plug into consistent power but still want protection from stray currents and galvanic corrosion, an isolation transformer may be sufficient.

Why ANG?
ANG Shore Power Converters™ combine universal voltage and frequency conversion with full electrical isolation, offering the most complete protection and flexibility on the market.
