Product Description:
The 09.F4.C1D-4A02 inverter is produced by KEB for the F4 Combivert Frequency Inverters series. It is an AC variable-frequency drive that converts a fixed 400 V supply into a controlled output waveform so that three-phase induction motors in automation cells can run at process-specific speeds. The product fits into Housing Type D, and the built-in brake transistor lets the drive route regenerative energy into an external resistor, allowing rapid, electrically damped motor stops without external chopper hardware.
The drive is assigned to the 400 V class, so its power components and insulation distances match the stresses found on standard European three-phase mains. During full operation it draws an input current of 4.5 A and delivers an output current of 4.1 A to the connected motor. At that current the apparent output power reaches 2.8 kVA, while the mechanical rating of the inverter tops out at 1.5 kW. A line cross-section of 1.5 mm² is sufficient for both mains and motor terminals, and upstream protection should be provided by a 10 A fuse that coordinates with the inverter’s stated oc trip current of 9 A. Internal semiconductor switching and control electronics dissipate 60 W, heat that is removed through the rear fin stack so forced cabinet ventilation is advised.
The braking path handles up to 10 A of DC, with a short-time current limit of 7.4 A on the motor side to clear heavy inertia loads. Safe energy dissipation requires a minimum brake resistor of 160 Ω; in most applications KEB recommends the typical 390 Ω element for balanced thermal cycling. The heatsink temperature rating of 79 °C defines the upper threshold at which the unit will derate to protect IGBTs. Power loss remains below the specified figure as long as ambient airflow keeps the sink below that point, ensuring stable service life for gate drivers and filter capacitors.
