Product Description:

The 09.F0.R01-3429 is a pre-assembled drive controller cabinet manufactured by KEB as part of the F0 Combivert Control Cabinets series. The unit combines a three-phase rectifier, inverter stage, protective fusing, and low-voltage supplies in one enclosure, so variable-speed motor control can be added without designing a separate panel. Its role in industrial automation is to deliver regulated AC power to a motor while providing convenient mounting and wiring points for auxiliary I/O and safety devices.

The power section supplies a continuous output of 4.1 A, corresponding to a nominal apparent power of 2.8 kVA at the drive terminals. With a maximum connected motor rating of 1.5 kW, the cabinet can operate small induction motors from a three-phase mains network. Internal losses are limited to 65 W, so standard forced-air ventilation is sufficient for most installations. Operation is permitted up to 3000 m above sea level, beyond which additional derating is required. A control-level fuse rated at 0.4 A protects the logic supply, and the minimum field wiring cross-section is 1.5 mm² to keep conductor temperature within limits. Total mass is 3 kg, allowing wall or frame mounting without heavy support hardware.

Low-voltage services for sensors and potentiometers are delivered through a stabilized auxiliary rail of +15 V at 30 mA and a reference rail of +10 V at 6 mA. Both rails share the same protective earth as the power stage and are isolated through optocouplers. Overcurrent protection is provided by a mains fuse and an intermediate DC link fuse, each rated at 10 A, to coordinate with the cabinet’s short-circuit capacity. The housing meets the IP20 ingress rating, meaning live parts are finger-safe when the door is closed, but the unit must be installed in a clean, dry environment.
