Product Description:

The 05.F0.R21-1228 is a compact drive control cabinet manufactured by KEB as part of the F0 Combivert Control Cabinets series. Designed for low-power automation, it combines an inverter stage, protective fusing, and terminal wiring in one IP-rated housing so a single induction motor can be energized from a single-phase mains line. This arrangement streamlines installation in conveyors, small pumps, and laboratory equipment by providing a ready-wired enclosure that maintains clearances for heat dissipation and field wiring access.

The enclosure carries a protection rating of IP20, meaning it blocks accidental finger contact while remaining open to panel-mount cooling airflow. It delivers up to 0.9 kVA of apparent power and accepts a supply at the standardized 50/60 Hz network frequency through one phase conductor. Internal safeguarding starts with a 0.4 A time-lag control fuse, while upstream protection may use a 10 A mains fuse matched to the cabinet's input terminals. Operation is permitted up to 3000 m altitude, after which output derating is required. For field wiring, the power block accommodates conductors down to 1.5 mm², and the cabinet profile measures 90 mm in width and 340 mm in height so it can fit standard switchboard rails.

Continuous load current is limited to 2.3 A, aligning with a maximum motor power of 0.37 kW in the 200-volt class. The inverter can switch devices up to 4 kHz, enabling smoother torque production at slow speeds without excessive switching losses. Its voltage category of 200 V suits small IEC-frame motors commonly found in material-handling carts. A relay contact rated 250 VAC at 0.2 A is available for run feedback, and humidity tolerance reaches 95% non-condensing for installation in production areas. Wiring should be routed so ventilation paths inside the cabinet remain unobstructed during operation.
