Variable Frequency Drive (VFD) / Frequency Converter · Frequency Converters & Drives
Siemens Marine SINAMICS G120 15kW 440V Marine is a marine Frequency Converter within the Frequency Converters & Drives group. Equipment of this type is typically installed in an electrical room, switchboard, motor-control centre or dedicated cabinet serving the connected shipboard load. Its primary duty is electrical power conversion, switching, protection or energy management associated with the Frequency Converter, and it depends on healthy incoming power, protection devices, internal power electronics or contactors, control logic, cooling and correctly terminated outgoing circuits. These stated values should be retained when the unit is identified or compared with neighboring variants. It normally interfaces with the vessel distribution system, connected motors or loads, control and alarm networks, protection circuits and cooling or ventilation arrangements.
