Magnus Yacht Shore Power Converters

Shore power conversion is a critical component of modern yacht electrical systems, allowing vessels to safely connect to a wide range of international shore power supplies while protecting onboard electrical equipment.

Magnus shore power converters are designed specifically for large yachts and mega-yachts, providing reliable power conversion between varying shore supply voltages and frequencies worldwide. By isolating the vessel’s electrical system from the shore supply, these systems ensure stable, regulated power while preventing disturbances that can affect sensitive onboard equipment.

Using shore power significantly reduces generator operating hours while the vessel is in port, improving onboard comfort by eliminating noise and vibration while lowering fuel consumption and maintenance requirements.

Magnus converters are engineered for high reliability, compact installation, and simplified operation, making them well suited for both new builds and refit projects in demanding superyacht environments.

Key Advantages of Magnus Shore Power Converters

  • Worldwide shore power compatibility (voltage and frequency conversion)
  • Stable, regulated output power for sensitive onboard systems
  • Electrical isolation between shore supply and vessel systems
  • Seamless transfer between shore and onboard power sources
  • Reduced generator runtime, fuel consumption, and maintenance
  • Compact modular design for efficient installation within limited engine room space

Through proper integration and commissioning, TESS ensures Magnus shore power systems operate reliably within the vessel’s overall electrical architecture, delivering stable power and dependable long-term performance.

Magnus FC100/200 Frequency Converter

Magnus FC100/200 frequency converters provide a reliable solution for supplying specialized onboard equipment that requires power characteristics different from the vessel’s primary AC distribution system.

On large yachts and mega-yachts, certain equipment, technical systems, and specialized machinery may require dedicated voltage or frequency conditions to operate safely and reliably. The Magnus FC100/200 converter allows these systems to operate independently while maintaining electrical stability within the vessel’s overall power architecture.

Designed for marine environments, the FC100/200 delivers clean, regulated power with minimal supply disturbances, protecting sensitive onboard equipment and ensuring reliable operation. The system incorporates isolated output supply, low earth leakage characteristics, and pure sinusoidal output to support critical technical systems.

Key Features

  • Clean sinusoidal output for sensitive equipment
  • Isolated output supply for system protection
  • Minimal supply disturbances during operation
  • Low earth leakage design
  • Digital touchscreen user interface for monitoring and control
  • RFI protection and rugged overload capability
  • Low-noise operation suitable for yacht environments
  • Marine-rated construction with IP43 protection and 45°C operating capability

Optional configurations include water-cooled operation and customized cabinet solutions to suit the vessel’s available installation space and operational requirements.

TESS provides engineering support, installation integration, commissioning, and troubleshooting for Magnus frequency converter systems to ensure reliable performance within the vessel’s electrical infrastructure.
