• Isolation: 3000 Vrms; efficiency up to 91%


• Standards: EN50155 railway version (optional); EN45545-2 fire & smoke certified

In marine fin stabilizer applications, this inverter supplies controlled AC power to brushless servo motors with electromagnetic brakes that drive active fin stabilizer systems manufactured by specialized marine stabilization companies. The inverter converts the vessel's onboard DC bus into the precise variable-frequency AC required for vector-controlled (FOC) motor drives, enabling fin rotation speeds exceeding 80°/s for real-time roll suppression at sea. Fin stabilizer manufacturers typically require inverters covering a 200–400 Vac output range (single-phase or three-phase) across a power spectrum from 5 kW on compact single-phase systems up to 30 kW on large three-phase superyacht installations. The inverter must sustain continuous duty cycles, resist salt-air corrosion and hull vibration, and comply with marine classification standards such as IEC 60945, DNV, and RINA, supporting yachts from 12 m to superyachts over 60 m.
