Product Description:
The 19.F4.C0H-3420 frequency inverter is produced by KEB and belongs to the F4 Combivert Frequency Inverters series. Intended for conveyor drives, pumps, and general motion tasks, the unit translates fixed-frequency mains power into an adjustable three-phase waveform so that motor speed follows real-time process demands. By embedding current, voltage, and temperature monitoring, it maintains stable operation while lowering energy use and mechanical wear. Its control method also supports smooth motor starting and controlled speed changes, which helps reduce shock on belts, couplings, and other driven components during normal operation.
Electrical connection is through three input phases with a nominal input current of 66 A, and conductors up to 25 mm² can be landed on the terminals. The recommended mains protection is an 80 A fuse, and semiconductor safeguarding is completed by an over-current trip that activates at 108 A. Internally, the power stage is clocked at a rated 4 kHz switching frequency, resulting in 540 W of total power loss that must be removed by the cabinet cooling system. On the output side, the inverter supplies a continuous current of 60 A and apparent power of 42 kVA, supporting motors up to 30 kW. Momentary load spikes are handled by a short-time capability of 90 A, which helps the drive maintain motion during brief acceleration or process disturbances.
The drive is assigned to the 400 V Class, allowing direct connection to standard industrial power systems in that voltage range. For quieter motor operation or highly dynamic positioning, the switching carrier can be increased to 16 kHz, provided thermal limits are respected. Shielded motor leads may run up to 100 m, and the enclosure carries an IP20 rating that requires installation inside a closed panel. Environmental suitability includes tolerance of up to 95% relative humidity under non-condensing conditions. Because the housing is not sealed against direct contact or debris, the surrounding enclosure should provide the necessary protection and airflow path for reliable service.
