Product Description:
The 16.F4.C0G-4F03 is a frequency inverter manufactured by KEB for the F4 Combivert Frequency Inverters series. This cabinet-mount unit sits between the mains supply and an induction or synchronous machine. It rectifies and modulates line energy so that motor speed and torque can be matched to process demands in conveyors, pumps, and general automation lines.
Designed for 400 V class networks, the inverter accepts a three-phase supply and draws a nominal input current of 36.5 A under rated conditions. A maximum upstream fuse rating of 50 A protects the installation, and copper conductors up to 10 mm² connect to the terminals without supplementary lugs. The carrier frequency is factory set to 8 kHz, matching the drive’s rated switching pattern, and full modulation bandwidth allows vector control of motors up to 15 kW. Within this window, the control electronics monitor thermal stress while the power stage switches through insulated-gate modules to sustain the commanded waveform. Passive losses are minimized by laminated busbars and a DC link choke, helping to maintain efficiency across the working envelope.
The output section delivers 23 kVA of apparent power with a nominal motor current of 33 A, and short-term peaks of 49.5 A allow acceleration without derating. If current rises to 59.4 A, the inverter issues an overcurrent trip to protect the semiconductor bridge. When the switching frequency is elevated to 16 kHz, the internal algorithm caps stall current at 9.7 A; at the default 8 kHz it reaches 21.5 A, providing extra breakaway torque for high-inertia loads. Total conduction and switching losses reach 310 W at full load, and that heat must be removed by the panel ventilation system. A shielded motor cable length of 100 m is supported, enabling the drive to be sited remotely from the machine while maintaining EMC compliance.
