Product Description:

The 17.F4.C0H-4K00 is a three-phase frequency inverter manufactured by KEB for the F4 Combivert Frequency Inverters series. The device converts a fixed industrial mains feed into a regulated AC output whose amplitude and frequency can be programmed by a controller or its local keypad. By placing this inverter between the supply and a standard asynchronous or synchronous motor, the system can provide closed-loop speed control, soft starting, and power delivery that matches the mechanical load in conveyor sections, pump skids, and general material-handling stations.

The power stage is designed for a wide DC link window and maintains operation from 420 VDC up to 720 VDC, a span that tolerates line fluctuations and braking energy. The rectifier is fed by a three-phase network whose phase-to-phase voltage should not exceed 500 V AC. At rated conditions, the unit draws 46 A of input current and delivers 42 A of sinusoidal output current to the motor. These figures correspond to thermal limits that must be respected when the ambient temperature approaches 45 °C, at elevations up to 2000 m and in environments with as much as 95% humidity. Mechanical integration is straightforward because the inverter weighs 14 kg and is cooled by natural airflow within a vented metal frame.

The control platform can supply a continuous apparent power of 29 kVA, and it can modulate the motor frequency up to 409.58 Hz to support high-speed spindles. When paired with machines that require elevated mechanical output, the drive supports motors rated to 18.5 kW while protecting them with an instantaneous overcurrent trip that activates at 75.6 A. Installation guidelines allow up to 100 m of shielded motor cable without additional output filters, which helps preserve signal integrity in electrically noisy cabinets. The enclosure’s IP20 classification means that fingers are guarded from live parts, but the unit must be mounted inside a closed panel to avoid dust or liquid ingress.
