Product Description:
The 10.F4.C3D-5000 is an AC frequency inverter produced by KEB and belongs to the F4 Combivert Frequency Inverters series. The unit converts fixed-frequency mains power into a variable voltage and frequency output for a three-phase induction motor, giving closed-loop speed control without mechanical gear changes. In material handling, pump, and fan installations, the drive maintains required torque while lowering energy use during partial-load operation. A compact footprint and an integrated cooling path simplify placement in crowded control cabinets. By adjusting output to the motor instead of throttling the driven machine, the inverter supports smoother process control across changing loads.
The drive stage relies on an internal IGBT bridge, switching at high frequency to synthesize a sinusoidal waveform for the motor phases. A built-in braking transistor routes regenerated DC-bus energy into a resistor during quick stops to keep the link voltage within safe limits. Continuous shaft work is supported up to 2.2 kW. Line protection must be provided with a 20 A mains fuse. Supply conductors with a cross-section of 2.5 mm² can be clamped directly to the terminal block. Cooling duties are handled by an integrated fan, which moves air through the heat sink channels to stabilize internal semiconductor temperature during full-current modulation.
The inverter supplies an apparent output power of 4 kVA, giving electrical headroom for acceleration peaks and flux-weakening operation. The cast aluminum heat sink may reach 85 °C before thermal derating begins, and a sensor tied to the control board trips the unit if this limit is exceeded. An onboard line filter suppresses conducted interference, allowing the installation to meet industrial EMC requirements without extra external components. Phase current sampling is optimized for standard three-phase motors, and the clean output waveform helps maintain stable motor operation on long cable runs.
