Product Description:

The 16.F2.R30-4006 drive inverter is produced by KEB within the F2 Combivert Drive Inverters series. It is an AC-input, variable-speed controller that supplies modulated power to induction or synchronous motors in automated machinery, allowing speed and torque adjustment without mechanical throttling. The unit installs in control cabinets and interfaces with external motor protection components to form the electrical axis of conveyors, pumps, or process equipment.

The inverter handles a three-phase supply and delivers a continuous output of 23 kVA while drawing a nominal line current of 33 A. It can operate motors rated up to 15 kW when its parameters are set to match the motor’s impedance. The internal IGBT stage switches at carrier frequencies up to 8 kHz, and upstream protection can use a maximum mains fuse of 50 A. At the maximum switching frequency, thermal dissipation reaches 770 W, so the cabinet must provide sufficient ventilation. Connection lugs accept conductors with a cross-sectional area of 10 mm², helping keep copper loss within acceptable limits. Line output must be reduced by 1% for every 100 m above the reference altitude. The 27 kg housing mounts vertically to maintain the required airflow paths.

The converter has an ingress protection rating of IP20, so live parts are guarded against finger contact, but the enclosure requires a clean, dry cabinet. It can start from a cold condition at −10 °C and operate continuously at ambient temperatures up to 45 °C without an output reduction, provided relative humidity does not exceed 90%. Its operating altitude extends to 3000 m, with the stated reduction in power and current applied as elevation rises above the reference altitude. These operating limits help protect the insulation, semiconductor junctions, and electrolytic capacitors from excessive electrical or thermal stress. The cabinet should prevent moisture, conductive dust, and other contaminants from reaching the inverter. Adequate spacing around the vertically mounted housing also supports natural airflow and allows internally generated heat to leave the enclosure.
