Product Description:
The 09.F4.C1D-4A03 frequency inverter is manufactured by KEB as part of the F4 Combivert Frequency Inverters series. Designed for installation between the incoming line supply and an asynchronous motor, it synthesizes variable voltage and frequency so motion sequences can be tailored to process demands without mechanical gear changes. Control terminals for a motor winding thermometer, marked OH and OH, allow the drive to monitor motor temperature and intervene before thermal limits are exceeded. Because the output frequency follows the commanded operating point, the inverter can adapt motor speed to changing load conditions without mechanical intervention.
The drive is dimensioned for motors up to 1.5 kW, while its converter stage can deliver an output apparent power of 2.8 kVA at rated conditions. A supply-side protection device no larger than 10 A is specified, so coordination with upstream circuit breakers remains simple. Field cabling connects to screw clamps that accept conductors with a cross section of 1.5 mm², matching common control-cabinet wiring practices. The enclosure is rated IP20, meaning live parts are guarded against touch and the unit is intended for installation inside a closed panel. Motor leads terminate on U, V, and W, and dynamic brake resistors can be wired to the dedicated PA and PB terminals for controlled deceleration during stopping.
The housing is compact at 240 mm high and 90 mm wide, so multiple inverters can be mounted in the same cabinet without taking excessive front-panel space. Four flange holes with a diameter of 5 mm provide a direct mounting option when DIN rail space is limited. The unit meets climatic category 3K3, which suits clean, dry control cabinets where condensation is not expected during normal operation. Its narrow profile also helps maintain clearance for cable routing and nearby components in shallow enclosures.
