PTK Maritime Static Frequency Converters
Marine-grade AC power conversion for ships, vessels, offshore systems and dockside applications with enclosure options for harsh environments. PTK maritime static frequency converters provide a controlled AC power supply for shipboard equipment, marine machinery and shore-to-ship applications where the available electrical supply does not match the requirements of the connected load
Maritime SFC Highlights
- 50Hz ↔ 60Hz Frequency Conversion
- Pure Sine Wave Output
- Three-Phase AC Power Conversion
- Transformer-Isolated Output
- Low Harmonic Distortion
- Continuous-Duty Operation
- Marine & Shipboard Applications
- IP54 Enclosure Options
Maritime SFC Description
Powertek’s Maritime Static Frequency Converters provide reliable, regulated AC power for shipboard, marine and offshore applications where the available electrical supply does not match the voltage or frequency requirements of the connected equipment. Powertek Maritime Static Frequency Converters use IGBT PWM technology to provide precise control of the output voltage and frequency. Transformer isolation can also be incorporated to provide electrical separation between the input supply and connected loads.
Built for Demanding Marine Environments
For installations where environmental conditions are a consideration, the converters can be supplied with options including IP54 enclosures, conformal coating and enhanced protection against humidity, condensation, salt spray and dust. Protection and monitoring features help provide safe and dependable operation, with options available for remote control, monitoring and communications.
Maritime SFC Applications
