Product Description:
The 10.F4.F1D-3440 is a frequency inverter manufactured by KEB within the F4 Combivert Frequency Inverters series. The COMBIVERT F4 unit is engineered for closed-loop speed and torque regulation of three-phase induction motors in automated machinery. The device employs a field-oriented control algorithm to modulate motor flux in real time, and its compact D-size housing allows dense cabinet layouts while maintaining full access to terminals and diagnostic ports. A built-in braking transistor supports dynamic deceleration without external chopper hardware, providing a self-contained solution for conveyor, pump, or tooling axes that require rapid stops.
The inverter delivers a nominal output power of 4 kVA and a continuous output current of 5.8 A. These values establish the thermal load on drive wiring and the upper limit for sustained motor torque. Incoming mains power can range from 305–500 V in a symmetrical three-phase network, matching the 400 V class distribution common in plant switchboards. Motors rated up to 2.2 kW can be operated from this frame size without additional step-down transformers. Carrier pulses are generated at 8 kHz, which minimizes current ripple and reduces acoustic noise in motor windings. This switching frequency also guides the selection of compatible EMC filters and cable shielding.
The enclosure has an ingress protection rating of IP20, making it appropriate for installation inside a protected cabinet. Internal components can operate within an ambient temperature range of -10 to 45 °C, so forced ventilation may be required when the drive is mounted near heat-producing equipment. The power section belongs to the 400 V class, which aligns fuse choices and contactor clearances with standard IEC guidelines. Continuous operation is allowed at relative humidity levels up to 95% without condensation. Suitable cabinet protection remains necessary when the inverter is used in washdown zones or humid production areas.
