Product Description:

The 09.F0.R31-3429 control cabinet is produced by KEB within the F0 Combivert Control Cabinets series. It houses drive-control electronics that distribute regulated power and feedback signals to variable-speed motor inverters in automated lines. By combining supply conditioning, protective components, and reference networks in one enclosure, the unit simplifies wiring and supports compact machine layouts often found in packaging, conveying, and light processing equipment. The cabinet is one rack unit high, which allows placement above or below adjacent drive modules.

The cabinet supplies a rated output of 2.8 kVA, enough to energize motors up to 1.5 kW without exceeding its thermal design. A maximum output frequency of 408 Hz supports fine speed resolution for high-pole machines, while a control fuse rated at 0.4 A time-lag protects the internal logic against inrush and short circuits. The protection class of IP20 permits installation in closed panels where accidental contact is limited by the host enclosure. Proper airflow is maintained by mounting the rack vertically and leaving 50 mm of clearance at the front, 50 mm at the sides, and 100 mm above. Reference inputs are routed through precision dividers that present 500 Ω to the current channel, 56 kΩ to the first voltage channel, and 4.4 kΩ to the secondary voltage channel, which helps match the sensing range of standard KEB drives while minimizing signal loading.

An overheat trip activates at 70 °C, so cabinet ventilation must keep internal components below this setpoint during continuous duty. Operation is permitted up to 3000 m above sea level, where reduced air density lowers cooling effectiveness, and up to an ambient relative humidity of 95% without condensation. The steel rack weighs 3 kg, which reduces mounting load on the panel structure. These installation limits are intended for enclosed industrial cabinets that provide the necessary physical protection and airflow space.
