Product Description:
The 05-F0.R03-1228 is a compact inverter cabinet manufactured by KEB for the F0 Combivert Control Cabinets series. It combines power conversion and basic motor control so that a single-phase utility feed can run a small three-phase induction motor with adjustable speed. Such self-contained units are integrated into conveyors, pumps, and positioning axes where space inside larger control enclosures is limited. Because the cabinet includes the inverter hardware, it can supply variable-frequency output to motors used in light-duty transport and positioning tasks.
Internal electronics run from a dedicated control supply of +15 V DC, separating logic power from the main drive section. The cabinet accepts one input phase and generates three output phases, delivering a rated output current of 2.3 A to the motor. Its power channel is limited to 0.9 kVA, and protection on the DC link is provided by a 6.3 A intermediate fuse; the upstream service should be fitted with a 10 A mains fuse. For fine speed resolution, the inverter can produce fundamental output frequencies up to 408 Hz, while carrier modulation can be raised to 4 kHz to reduce audible noise. All terminations sit on a rack-style housing that slides into multi-axis frames, and the minimum wire size is 1.5 mm² for the stated current range. No cooling fan is installed, so heat is removed by natural convection through the card guides and vent slots. This passive cooling arrangement reduces moving parts inside the cabinet and keeps airflow requirements simple.
An ingress rating of IP20 prevents finger access to internal parts and requires installation inside a closed panel. The drive can energize motors up to 0.37 kW, and larger motor loads require a different unit in the series. Continuous operation is allowed at ambient humidity as high as 95% RH when condensation is avoided, and installation heights up to 3000 m are permitted without derating. The unit is intended for protected indoor cabinet mounting rather than direct exposure on the machine.
