EFYN Frequency Converters
Every Frequency You Need
EFYN are frequency converters capable of handling conversion between different grid standards, typically from 50 Hz to 60 Hz and vice versa. This allows powering equipment, accessories, and small appliances for guests and crew without the need for external adapters.
Thanks to the integrated Active Front End (AFE) technology, EFYN not only convert frequency but also improve the power quality drawn from the yacht’s main bus, ensuring:
- Pure Sine Wave Output: Provides clean and stable energy, protecting sensitive electronic devices.
- Galvanic Isolation: The output is fully isolated to protect equipment from interference and potential ground faults.
- Interference Reduction: AFE minimizes power disturbances and harmonics, ensuring interference-free operation.
Key Advantages and Features
EFYN combine high performance and reliability, offering a complete solution for onboard frequency management:
- Reliability and Performance: Designed to provide stable power supply even in the presence of voltage or frequency disturbances.
- Operational Efficiency: High AFE efficiency helps reduce operating costs.
- Safety: RFI protection, galvanic isolation, and low earth leakage safeguard sensitive equipment and users.
- Robustness: High overload capacity and robust air cooling in an IP43-rated cabinet allow continuous and reliable operation up to 45°C.
- Intuitive Control: Digital touchscreen displays enable immediate system monitoring and management.
- Quiet Operation: Optimized design ensures silent performance, enhancing onboard comfort

Onboard Automation
We develop automation systems for the control of onboard components, including benches, tables, and hatches. Our technology is based on the integration of linear actuators, dedicated PLCs, and intuitive HMI interfaces.
For the movement of telescopic pedestals, for example, we use a low-voltage electric control system with “dead man” buttons to ensure maximum safety. The structure is made of AISI 316 stainless steel or lightweight aluminum alloys suitable for the marine environment.
Given the need for synchronous movement of multiple units (10 for the seats and 4 for the table), control is managed by two dedicated PLCs with separate circuits. Our design approach favors the use of multi-stage pedestals with minimal space requirements below deck, facilitating installation in confined areas or during the later stages of yacht construction.
