Product Description:
The 14.F4.C3E-4M00 frequency inverter is produced by KEB as part of the F4 Combivert Frequency Inverters series. This unit converts fixed-frequency three-phase mains power into a variable voltage and frequency output so that induction or permanent-magnet motors can be regulated for speed and torque in automated machinery, conveyors, and process equipment. By embedding the control electronics and power stage in a single IP20 housing, the device fits directly inside a switch cabinet without external modules. Its integrated layout keeps the drive package compact and supports use in equipment where cabinet space is limited.
It draws a maximum input current of 18.1 A from a three-phase line in the 400 V voltage class at standard 50/60 Hz mains frequency. For pulse-width modulation, the power stage uses a rated carrier frequency of 8 kHz. When fully loaded, the inverter can deliver 11 kVA to the motor terminals, which matches its intended thermal capacity and conductor sizing. Internal conformal coating and finger-safe terminals support IP20 protection, limiting access to hazardous parts while relying on the surrounding enclosure for additional protection. These input and enclosure features suit installation in enclosed industrial control cabinets.
On the motor side, the converter provides an output current of 16.5 A, suitable for driving machines that need up to 7.5 kW of shaft power. For dynamic or acoustically sensitive applications, the carrier can be raised to a maximum of 16 kHz, which can improve running smoothness while increasing switching losses. Those losses amount to 240 W at nominal operation and must be removed by panel airflow. Wiring guidelines call for 4 mm² conductors, 0.5 Nm terminal torque, and a 25 A gG upstream fuse so the drive operates within its short-circuit protection limits. This combination supports stable installation and dependable operation under normal cabinet cooling conditions.
