Product Description:

The 09.F0.R11.3429 control unit belongs to the F0 Combivert Control Cabinets series produced by KEB. Housed as a compact cabinet, it integrates a frequency inverter that interfaces with three-phase mains supplies to regulate asynchronous and synchronous motor speed. In automated production lines, this product supplies variable voltage and frequency so pumps, conveyors, or process drives can match load demand while remaining inside the electrical limits established for the machine group.

The cabinet operates from a three-phase network nominally rated at 400 V, and KEB specifies a mains fuse of 10 A to coordinate upstream protection with its internal components. When driven at that supply, the inverter can deliver a continuous output current of 4.1 A, corresponding to a rated apparent power of 2.8 kVA at the motor terminals. Mechanical work is supported up to 1.5 kW of shaft power, adequate for small fans or feed rollers. For process tasks that need high spindle speed, the modulation stage produces carrier-based output up to 408 Hz, far above mains frequency. All electronics sit inside an enclosure verified to IP20, so the unit must be mounted in a panel where operators cannot touch energized parts, but no additional dust sealing is required. Wire terminations accept 1.5 mm² conductors, and a minimum 100 mm vertical air gap is recommended to aid convection.

Thermal and environmental limits frame how the cabinet is placed. Heat generated by switching losses reaches 65 W at a 4 kHz carrier, and that heat is removed passively provided the available airflow is not restricted. The assembly weighs only 3 kg, so it can be fixed on light-gauge backplates without reinforcement. Operation is permitted from -10 °C up to 45 °C with ambient humidity to 95%, and performance remains stable up to 3000 m above sea level before derating is needed.
