Fin stabilizer Inverter 1500W

The ODS-1500 is a single-phase sinusoidal DC/AC inverter rated 1200–1500 W with selectable 120 or 230 Vac output. Its wide DC input range from 12 to 110 Vdc covers battery bus voltages from 12 V automotive to 110 V railway strings. A railway version with tropicalized circuits and EN50155 compliance is available for all models.

Internal forced-air cooling and efficiency up to 91%. Maximum average power and peak current protection, input under-voltage disable, RS232 control via PAM Tool, and isolated relay alarm contacts ensure robust integration. Accessory: ACI-3000 inrush current limiter.

In marine fin stabilizer applications, this inverter supplies controlled AC power to brushless servo motors with electromagnetic brakes driving active fin stabilizer systems such as the CMC Marine Stabilis Electra series. 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. Operating across a 200–400 Vac output range (single-phase or three-phase depending on stabilizer model), it 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. Supported stabilizer range spans yachts from 12 m to superyachts over 60 m.
