Product Description:

The 10.F0.R11-4003 control cabinet is part of the F0 Combivert Control Cabinets series produced by KEB. It functions as the power interface between the plant mains and a matched inverter stage, enabling regulated motor operation in automated lines. By integrating protective fusing, power conversion circuitry, and system I/O in a single rack, the cabinet simplifies installation and ensures that downstream drive components receive stable DC power and control signals required for precise motion and process control. This arrangement separates line-side power handling from the inverter section, which helps organize wiring and keeps power and control connections grouped in one location.

Incoming power is supplied on three phases at 400 V, and the cabinet can deliver up to 4.0 kVA of apparent power to the connected inverter. Under rated conditions, the output current reaches 5.8 A, supporting motors up to 2.2 kW. Thermal losses are limited to 75 W, maintaining internal temperatures within component tolerances when mounted inside a larger panel. Overcurrent events are restricted by an intermediate fuse of 16 A, and the mains side must be protected with a 10 A fuse together with a separate 0.4 A control circuit fuse. This layout supports drive systems that need both a main power path and low-level reference connections inside the same cabinet.

The housing carries a protection rating of IP20, so the cabinet must be mounted inside a sealed machine enclosure when airborne dust or dripping fluids are present. An integrated auxiliary rail supplies 15 VDC at 30 mA for encoder excitation or small control relays, avoiding the need for an external power module. Operation is permitted up to 3000 m above sea level without output derating. The enclosure weighs 4 kg, and reference channels provide 10 VDC and 6 mA for analog speed or torque commands. The auxiliary supply and reference outputs let the cabinet support small feedback devices and command circuits without requiring another low-power source nearby.
