Product Description:

The 07.F4.C1D-4A01 is a frequency inverter manufactured by KEB as part of the F4 Combivert Frequency Inverters series. Installed between a three-phase supply and an induction motor, it converts fixed mains power into a variable-frequency output that lets automation controllers dictate speed and direction. The device therefore fulfills the basic drive task in conveyors, mixers, and small process stations. Its cabinet-installable IP20 housing is intended for sheltered machine rooms rather than exposed factory floors, and it provides the electrical interface that links control logic to mechanical motion. It can be used where process speed must change during operation without requiring mechanical ratio changes.

Electrical throughput is based on a three-phase input and a nominal line draw of 2.8 A. With a motor rating of 0.75 kW, the inverter can deliver continuous shaft power through an output stage rated for 1.8 kVA. The rated output current reaches 2.6 A, while upstream protection may use a maximum line fuse of 10 A. Both the rated and maximum carrier frequencies are limited to 4 kHz, a value that balances acoustic noise against switching losses. This switching limit helps keep heat generation predictable in a compact enclosure. Power enters through conductors no smaller than 1.5 mm², satisfying the minimum cable cross-section requirement and helping maintain terminal stability.

Thermal behavior is anchored by a heat sink that may rise to 85 °C when the inverter is fully loaded, during which internal dissipation is about 45 W. An integrated brake transistor channels regenerated energy into external resistors; the braking circuit accepts a minimum resistor of 160 Ω but is optimized around a typical value of 680 Ω. This braking arrangement supports repeated stopping cycles where the motor returns energy to the drive. These limits help protect semiconductor junctions while maintaining deceleration torque. The unit is classified in climatic category 3K3, so it tolerates filtered control-cabinet air with moderate humidity and dust.
