Product Description:
The 10.F4.C3D-3460 is a frequency inverter manufactured by KEB for the F4 Combivert Frequency Inverters series. It receives fixed-frequency three-phase power, reconstructs the waveform internally, and feeds an adjustable AC output to induction motors used in conveying, pumping, and positioning tasks on automated lines. By matching motor speed to real-time load requirements, the device improves energy use and removes the need for mechanical speed-changing components inside modern control cabinets. Electronic speed control also helps reduce mechanical shock during acceleration and deceleration.
This inverter is built for the 400 V supply class and connects to three input phases through conductors with a 2.5 mm² line cross section. Under rated conditions, it draws a nominal input current of 6.4 A and converts that to an output capable of delivering 4 kVA of apparent power. The corresponding output nominal current is 5.8 A, providing adequate headroom for motors that must track process speed commands precisely. Steady operation dissipates 80 W of power loss, while an internal sensor ensures the heat sink never exceeds 85 °C. To protect the power stage, an over-current trip activates at 12.7 A, and that threshold is coordinated with the recommended upstream fuse to avoid unnecessary shutdowns during normal switching.
The drive can propel motors up to 2.2 kW continuously and still tolerate transient load peaks by sourcing a short-time current of 10.4 A. Rapid deceleration is supported by an integrated brake chopper that routes up to 15 A into an external resistor; the resistor must be no lower than 82 Ω, with 270 Ω given as a typical value for frequent stops. The external resistor absorbs regenerated energy when the motor acts as a generator during braking, which helps support controlled stopping and protects the DC link.
