Product Description:

The 16.F4.C2H-4G01 frequency inverter is produced by KEB as part of the F4 Combivert Frequency Inverters series. It functions as a speed-controlling AC drive that converts fixed-frequency mains power into a variable-frequency output, enabling closed-loop regulation of three-phase induction motors in automated machinery. By adjusting motor speed instead of restricting mechanical output, the unit allows process equipment such as conveyors, mixers, and pumps to maintain throughput while reducing energy consumption and mechanical wear. This method also gives the connected machinery more precise control over acceleration, deceleration, and operating speed under changing process demands.

The inverter uses the Compact control mode, with regulation algorithms and parameters organized into a straightforward menu structure. For plant networks that exchange setpoints and status bits digitally, a built-in InterBus interface provides deterministic fieldbus connectivity. The mechanical envelope uses an H-size housing, so mounting clearances, cooling airflow, and terminal spacing correspond to other H-class Combivert drives. Electrical output supports motors up to 15 kW, giving the device enough capacity to run medium-power machinery without an external step-up transformer. The permitted ambient operating temperature ranges from -10 to 45 °C, within which the rated current, switching frequency, and overload values remain valid. The enclosure has an ingress protection rating of IP20, which prevents accidental contact with live parts but requires installation inside a control cabinet for protection against dust and water.

An integrated EMI filter is included, reducing conducted electrical interference and eliminating the need for a separate external EMI filter in suitable installations. During storage or operation, the electronics tolerate relative humidity levels up to 95% without condensation, supporting use in facilities where cooling or dehumidification may be intermittent. The product designation COMBIVERT F4 places this model among inverters that use a common control architecture, parameter numbering system, and diagnostic structure. These shared controls allow consistent configuration and fault analysis across compatible power classes without changing the basic operating workflow.
