Mastervolt Mass GI 6 Isolation Transformer - 6 kW 120/230 V (55010600)

The Mastervolt Mass GI 6 (Part Number: 55010600) is a high-performance, compact $6.0\text{ kW}$ High-Frequency Isolation Transformer designed to safely isolate a vessel's AC electrical system from shore power supplies operating at either $120\text{ V}$ or $230\text{ V AC}$ ( $50/60\text{ Hz}$ ). Shore power connections present significant galvanic corrosion risks to underwater metal fittings (propellers, shafts, thru-hulls, and sterndrives) due to stray DC earth currents flowing between the shore ground and the vessel's hull.

By employing advanced high-frequency switch-mode technology rather than traditional heavy copper/iron low-frequency core designs, the Mass GI 6 delivers maximum power density in an ultra-lightweight ( $10\text{ kg}$ ) package—saving up to $80\%$ of the weight compared to standard toroidal transformers. It ensures complete electrical safety aboard, prevents dangerous shore-to-boat ground loops, and includes built-in soft-start control to eliminate AC shore breaker tripping caused by high startup inrush currents.

Key Features

Galvanic Corrosion Protection: Safely isolates onboard ground from shore ground, preventing stray current electrolysis from destroying underwater hull metals.
Ultra-Lightweight & Compact: High-frequency technology reduces weight to just $10.0\text{ kg}$ ( $22\text{ lbs}$ ), making it ideal for performance yachts and weight-sensitive hulls.
Auto-Ranging Multi-Voltage Compatibility: Supports $120\text{ V}$ and $230\text{ V}$ shore power grid inputs ( $50\text{ Hz}$ or $60\text{ Hz}$ ) for global cruising capability.
Integrated Soft-Start Control: Inhibits high current spikes on initial connection to prevent tripping dockside AC shore circuit breakers.
Seamless Parallel Operation: Two or more Mass GI 6 units can be connected in parallel to expand total onboard AC power capacity up to $12\text{ kW}$ or higher.
