Product Description:
The 14.F2.R10-4009 is a three-phase AC drive inverter produced by KEB within the F2 Combivert Drive Inverters series. As a mains-powered frequency converter, it modulates voltage and frequency to regulate motor speed and torque, enabling precise conveyor, pump, and fan control inside automated equipment racks and machine tools. The model integrates an internal braking transistor so regenerated energy from decelerating loads can be dissipated without separate hardware.
It draws a three-phase input line within the voltage window of 305 to 500 V, permitting operation on common 400 V industrial grids. Supply frequency is 50/60 ±2 Hz, so the inverter tolerates either domestic or export mains standards without retuning. Pulse-width modulation is generated at carrier rates up to 16 kHz, and a higher switching frequency reduces audible noise while smoothing motor current. At the output, the unit can deliver a continuous phase current of 16.5 A, corresponding to an apparent power of 11.0 kVA under nominal conditions. The associated upstream protection device should be sized no larger than 25 A, matching the maximum mains fuse rating given for this unit.
With an enclosure rated at IP20, the drive is intended for installation inside a control cabinet where finger-safe touch protection is sufficient and no direct liquid exposure exists. When connected to appropriately cooled machines, it can support motors up to 7.5 kW, aligning its output range with medium-size production machinery and HVAC equipment. During logistics or spare-part stocking, the electronics withstand ambient extremes from -25 to 70 °C, reducing the risk of condensation or thermal damage before installation. Additional design details such as a permissible wire cross-section of 4 mm² and an output voltage that tracks the mains amplitude across all three phases help simplify panel layout and support predictable motor behavior across the operating speed range.
