Product Description:
The 15.F4.CMG-4F04 frequency inverter is manufactured by KEB and belongs to the F4 Combivert Frequency Inverters series. This drive converts fixed three-phase line power into an adjustable output that controls motor speed and torque, allowing conveyors, pumps, and machine tools to run at the precise rate required by the application. By providing closed-loop regulation and programmable ramps, the unit supports consistent production quality and extends mechanical component life in industrial automation cells.
Electrically, the inverter is designed for the 400 V voltage class and connects to a three-phase mains network. Under continuous duty, the line draws a nominal input current of 26.5 A, while the inverter delivers an output nominal current of 24 A to the motor. This corresponds to a nominal output power of 17 kVA, giving the drive sufficient capacity for medium-sized production equipment. During dynamic events such as acceleration, the power section can tolerate a short-time current of 30 A, enabling temporary overload without triggering protective shutdowns. Conductors up to 6 mm² can be landed on the line terminals, and the installed mains fuse must coordinate with the inverter’s overcurrent trip threshold of 36 A.
Environmental and thermal limits affect cabinet placement. Its housing carries an IP20 protective rating, so the enclosure must be installed in a clean compartment. The climatic category 3K3 and permissible relative humidity of 95% without condensation describe ambient conditions typical of factory floors. A heat-sink temperature ceiling of 90 °C sets the basis for airflow calculation, and an integral sensor monitors internal thermal conditions. For branch-circuit protection, KEB specifies a maximum fuse size of 35 A; combined with the drive, this supports a motor rated up to 11 kW. The unit is intended for installation in a clean control cabinet with appropriate airflow and proper branch protection.
