FPP M quayside and onboard frequency converters

Frequency converters are designed to supply receivers with different voltage and frequency parameters than the main power network. They are used in the power infrastructure of ports, airports, military and offshore installations. Two-way energy flow and power flow adjustment are also possible. They are made using the state-of-the-art IGBT technology. They are characterized by high stability of output voltage, low interference, resistance to overload. Their other features include: resistance to external interference and changes in power supply parameters, protection against short circuits, too low and too high voltage, galvanic isolation of the output circuit from the power circuit, automatic operation, fully maintenance-free operation, high efficiency and Power Factor close to 1.


Our equipment is manufactured in accordance with the requirements of Ship Classification Societies.
