Product Description:

The 09.F0.200-1229 cabinet is built by KEB and belongs to the F0 Combivert Control Cabinets series. It is a self-contained inverter assembly that delivers variable-frequency power to induction motors used in automated machinery. The enclosure ships with line protection and drive electronics already wired, so the cabinet can be mounted and connected with less panel work. This design simplifies installation for conveyors, small process pumps, and indexing stations that need reliable speed control from a compact package.

The cabinet connects to a three-phase AC supply rated at 230 V AC, and the drive section can source up to 7.0 A while delivering a continuous apparent power of 2.8 kVA. For applications that demand fast spindle or blower operation, the inverter can raise the output to a maximum of 408 Hz; at that frequency, it can still support a motor with a nominal output of 1.5 kW. Circuit protection uses a 0.4 A control fuse for the logic circuit, a 16 A intermediate fuse on the DC link, and a 20 A mains fuse as the upper limit for branch protection. The overcurrent trip activates at 200% of rated current, while DC bus monitoring disconnects the drive above 400 V and below 250 V to prevent overvoltage and undervoltage conditions. All components are enclosed to an IP20 rating, permitting safe installation inside a ventilated control room or panel.

Thermal and site limits are stated clearly. Continuous operation is allowed up to 45 °C, and the inverter stage releases about 70 W of heat at a 4 kHz switching frequency, so cabinet ventilation must accommodate that load. Power wiring must be at least 2.5 mm² to handle current and fault levels, and the complete assembly can be mounted at altitudes as high as 3000 m without derating. These values support cooling-air calculations, conductor sizing, and site planning.
