Product Description:
The 14.F4.050-2009 inverter is produced by KEB and belongs to the F4 Combivert Frequency Inverters series. Designed for motor control in automated machinery, the unit modulates DC-bus energy to supply adjustable voltage and frequency to an induction or synchronous motor. This operation allows precise speed regulation and supports consistent processes on the factory floor. As part of a modular drive platform, the inverter fits into cabinet systems where compact installation and standardized wiring are priorities.
With a maximum rated motor power of 7.5 kW, the drive covers midrange conveyor, pump, and fan axes. It draws its input from a DC supply, so it can connect directly to a shared intermediate bus or rectifier stage without requiring a second mains bridge. The enclosure carries an IP20 rating, providing protection against finger contact while requiring installation inside a protective panel. Reliable electronic operation is supported at ambient temperatures from -10 to 45 °C; operation above this range requires derating or forced ventilation. Integrated dynamic-braking hardware includes a braking transistor, resistor, and filter. This package dissipates regenerated energy and attenuates conducted emissions without requiring separate braking components.
The unit is classified as COMBIVERT F4, placing it within the corresponding drive platform and parameter structure. It tolerates ambient relative humidity of up to 95%, provided condensation is prevented. This moisture tolerance supports operation in humid production areas when the inverter is installed in a sealed cabinet. Suitable cabinet cooling must maintain the permitted operating temperature around the electronic components, particularly when the drive operates near its rated motor power. Cabinet heaters may also be needed where temperature changes could create condensation after shutdown or during startup. The DC-bus connection supports centralized rectification and permits regenerated energy from one connected axis to be used by another axis when the system design allows energy sharing.
