Mastervolt 88000705 Mass GI 7 Isolation Transformer 7000W 32A

The Mastervolt Mass GI 7 is a high-frequency isolation transformer designed to provide galvanic isolation between AC shore power and your vessel's onboard electrical system. Using advanced switch-mode technology, this unit eliminates the heavy, bulky components of traditional transformers, resulting in a compact and lightweight design that delivers 7000 watts of continuous power.

Galvanic Isolation Protection: The Mass GI 7 creates electrical separation between shore power and your boat's AC system, preventing galvanic corrosion that can damage underwater gear, through-hull fittings, props, shafts, and aluminum hulls. This protection is essential when connecting to questionable shore power systems or when neighboring vessels may be transmitting stray currents through the water.

Key Features:

• Compact High-Frequency Design: Solid-state switch-mode technology eliminates traditional heavy transformer cores, delivering full 7000VA capacity in a unit weighing just 22 pounds
• Universal Voltage Compatibility: Accepts input voltage from 90-255V AC and frequency from 45-65 Hz, maintaining the same output voltage and frequency (±5%) for worldwide compatibility
• Scalable Capacity: Multiple units can be parallel-coupled through MasterBus communication to double or triple capacity as needed
• Integrated Soft Start: Manages inrush current when connecting to shore power, with LED indicator displaying load status
• Silent Operation: No vibration or hum allows installation in any orientation on walls or floors without rubber isolation mounts
• MasterBus Integration: Connects to Mastervolt's MasterBus network for remote monitoring, alarm notification, parallel configuration, and integration with other onboard systems
• Variofan Cooling: Variable-speed fan cooling adjusts based on load and temperature for efficient, quiet operation
