Product Description:

The 12.F0.R11-4012 is a drive-integrated control cabinet delivered by KEB within the F0 Combivert Control Cabinets series. It is intended for three-phase induction or synchronous motor control in automated machinery, giving plant builders a compact enclosure that combines power electronics, control logic, and field wiring points for closed-loop speed regulation across a production line. Its integrated layout keeps the power stage and control functions in one cabinet assembly, which helps simplify installation in centralized machine systems.

The inverter section modulates its output with a switching clock of 4 kHz, so the generated voltage waveform has low harmonic distortion at the motor terminals. It is supplied from a three-phase mains network rated at 400 V, and upstream protection is achieved with a 20 A time-delay fuse. The unit can deliver a continuous output current of 9.5 A, which corresponds to an apparent power of 6.6 kVA. The output frequency can reach 408 Hz, which supports high-frequency spindle or blower operation. Conductors for the power stage must be at least 2.5 mm² to meet thermal limits under full load. Two reference outputs, one providing 10 V and the other sourcing up to 6 mA, allow analog setpoint or sensor supply functions. The control electronics accept three input phases and rely on the internal DC link to maintain regulation when mains fluctuations occur.

Cabinet integrity is classified at IP20, so installation inside a larger switchboard is necessary when environmental debris is present. The rack itself weighs 4 kg, which keeps handling manageable during service work. Thermal losses reach 115 W at rated load, so adequate panel airflow must be provided. The power stage is sized to operate motors up to 4 kW, matching many conveyor, pump, and fan duties. Two open-collector outputs rated for 30 V and 30 mA transmit status to remote PLC inputs.
