09.F0.R01-3429 by KEB

The 09.F0.R01-3429 is produced by KEB as part of the F0 Combivert Control Cabinets series. It functions as a cabinet-mounted inverter that conditions three-phase mains power for precise motor control in automated machinery. By integrating power electronics, fuses, and low-voltage interfaces in a single enclosure, it simplifies installation where compact variable-speed control is required on production lines, conveyors, or packaging stations.

This cabinet accepts a three-phase supply and protects the incoming path with matched mains and intermediate fuses rated at 10 A, while a 0.4 A control fuse protects the low-energy logic path. Under continuous load, the drive section delivers a rated output current of 4.1 A and a corresponding apparent power of 2.8 kVA. The drive supports a motor output of up to 1.5 kW, making it suitable for small induction or synchronous motors used in auxiliary axes. Thermal losses are limited to 65 W, allowing cabinet air to be managed with basic convection when ambient temperatures remain moderate. Wiring to the terminals must use conductors with a cross-sectional area of at least 1.5 mm². The housing has an IP20 enclosure rating, which provides protection against finger contact but does not protect against liquids.

The control section provides a stabilized auxiliary rail of +15 V at 30 mA and a reference rail of +10 V at 6 mA for sensors or potentiometers that provide speed commands. Operation is permitted at elevations up to 3000 m without output derating, supporting installation in high-altitude facilities. The unit has an overall mass of 3 kg, so it can be mounted on lightweight panels or added to mobile equipment frames. The coordinated fuse arrangement separates protection for the incoming supply, intermediate circuit, and low-energy control electronics.
