Product Description:
The 09.F4.S1D-3420 is an AC motor frequency inverter manufactured by KEB as part of the F4 Combivert Frequency Inverters series. In industrial automation this unit modulates a fixed-frequency mains supply to deliver a variable output frequency and voltage, allowing process machinery to adjust speed, torque, and energy consumption in real time. It is intended for installation inside a control cabinet, where its compact form factor integrates with other drive and PLC components that supervise three-phase induction motors on conveyors, pumps, and small production cells.
The inverter operates on a three-phase mains feed in the 400 V class and is housed in an IP20 enclosure, so it requires a clean, ventilated environment. During steady operation it draws a nominal input current of 4.5 A and switches at a carrier frequency of 4 kHz. The internal power stage supplies a nominal output of 2.8 kVA with 4.1 A of continuous current. For transient demands it can deliver up to 7.4 A, while an overcurrent trip activates at 9 A. A 10 A mains fuse is recommended to coordinate with this threshold and isolate the drive during a fault. Heat generated by the IGBTs is conducted to an integral heat sink, and the design limits switching losses to 60 W so the power devices remain within safe thermal margins.
The mechanical side of the design is sized for motors up to 1.5 kW, and the heat sink temperature may rise to no more than 85 °C. A factory-installed braking transistor works with a minimum external resistor of 160 Ω to absorb regenerative energy, and the circuit regulates deceleration currents up to 5 A without exceeding its short-time rating. This arrangement supports repeated stops during cycles that mix acceleration, constant speed, and controlled braking.
