Product Description:

The 10.F0.220-4009 is a drive-ready cabinet assembled by KEB for the F0 Combivert Control Cabinets series. Designed for installation inside a larger machine frame, this product combines a line rectifier, DC link, inverter stage, and protective wiring into one IP20 metal enclosure. Its role in industrial automation is to convert fixed mains power into a variable-frequency, variable-voltage output so that connected AC motors can accelerate, decelerate, and hold target speeds with minimal energy loss.

The cabinet interfaces with plant power through protected line-side circuits. A control circuit protected by a 0.4 A miniature fuse powers the logic boards, while the main DC link is safeguarded by a 16 A intermediate fuse and a supply fuse limited to 10 A. The cabinet expects a three-phase input and tolerates line voltages up to 500 V, with its nominal operating point set at 400 V. Internally, the inverter can deliver 5.8 A of continuous motor current and up to 4.0 kVA of apparent power. The power stage is sized for mechanical loads requiring up to 2.2 kW of shaft output. For field wiring, conductors down to 1.5 mm² are accepted, which simplifies connection to smaller motors. Installation is permitted up to 3000 m above sea level, and the enclosure has an IP20 rating for use inside closed panels.

The cabinet operates across a broad ambient and output-frequency range. It starts reliably at temperatures as low as -10 °C and operates continuously up to 45 °C when adequate airflow is provided. Its inverter section modulates the output frequency from zero up to 408 Hz, which supports motor applications that run above standard 50/60 Hz operation. When utility conditions sag, the electronics remain functional down to 305 V, providing added tolerance for distribution drops. This operating range suits applications such as pumps, fans, and conveyors that require stable motor control under varying supply and load conditions.
