Product Description:

The 09.F4.C3D-4M00 is a frequency inverter manufactured by KEB for the F4 Combivert Frequency Inverters series. It converts fixed-frequency mains power into a variable output for closed-loop speed and torque regulation in industrial drives. A compact control insert is fitted inside housing type D, allowing shallow panel depth while providing direct access to terminals and parameter keys. Used on conveyors, pumps, or ventilation fans, the unit modulates motor voltage and frequency to match load requirements and support long service life.

It delivers an output nominal power of 2.8 kVA, so the inverter can supply 2.8 kilovolt-amperes of apparent power to the connected load. The rated motor power of 1.5 kW indicates the continuous shaft rating the drive can handle without derating. The input frequency range is 50/60 Hz ±2, allowing one model to operate in regions that use either standard frequency. For short-circuit protection, KEB specifies a maximum mains fuse of 10 A, which limits fault current energy delivered to the input rectifier. An enclosure protection rating of IP20 provides touch-safe construction, but the drive must be installed in a clean, ventilated cabinet away from water spray.

Supply conductors up to 1.5 mm² can be connected to the power terminals, matching the stated line cross section. Full electrical performance is maintained up to a site altitude of 2000 m, so the unit remains suitable for most indoor industrial installations. The drive is intended for climatic category 3K3, which covers indoor locations with moderate temperature, dust, and low condensation. An integrated filter and braking transistor suppresses conducted emissions and dissipates regenerative energy during fast deceleration, removing the need for an external RFI filter or a separate braking chopper while preserving the compact form factor.
