Product Description:

The 09.F0.C000-1229 is a pre-wired drive cabinet supplied by KEB as part of the F0 Combivert Control Cabinets series. Designed for small motor-driven processes, the enclosure consolidates power electronics, line protection, and reference circuitry into a single panel that can be mounted near the machine. In factory automation, this cabinet serves as the interface between the 230 V supply network and an AC motor, allowing adjustable speed control while providing coordinated short-circuit and thermal protection for connected loads. The integrated arrangement reduces the amount of external wiring needed between the incoming supply, the protective devices, and the motor control section.

The cabinet is rated for a supply of 230 V and delivers a continuous output of 7.0 A, which is equivalent to 2.8 kVA at the inverter terminals. With a maximum carrier frequency of 408 Hz, the integrated drive can operate high-speed induction or synchronous motors across a broad speed range. The housing is rated IP20, so the panel must be installed in a closed electrical enclosure or protected machine compartment. A 20 A line fuse, a 16 A intermediate fuse, and a 0.4 A control fuse separate fault currents across the power path. Reference circuits are monitored through 56 kΩ voltage and 500 Ω current feedback resistors, and the design requires 100 mm of clearance above and below the enclosure for convection cooling.

During operation, the inverters dissipate 70 W of heat, so 50 mm of side clearance is required to maintain airflow. The power stage can energize motors up to 1.5 kW, and it retains full output at elevations up to 3000 m without derating. The unit can operate in environments with ambient moisture up to 95% relative humidity, provided condensation is avoided. These operating limits suit enclosed machine sections where ventilation space is controlled and non-condensing moisture may be present during normal use.
