Product Description:

The 16.F4.COG.M441 is a frequency inverter produced by KEB within the F4 Combivert Frequency Inverters series. Designed for integration into motor-driven machinery, it converts fixed mains voltage into a variable AC output so that induction or synchronous motors can be started smoothly, run at regulated speed, and stop under controlled deceleration. This flexibility allows the inverter to match motor torque and speed to changing load conditions while keeping electrical and mechanical stress low.

The drive supplies an output nominal current of 33 A, giving sufficient RMS amperage to energize motors up to the listed mechanical limit of 15 kW. At that loading, the electrical side delivers 23 kVA of apparent power, which helps with upstream protection and cable sizing. A rated switching frequency of 8 kHz minimizes audible noise and current ripple in standard duty, while a ceiling of 16 kHz is available for applications that require finer torque resolution at the cost of higher dissipation. Even with these higher pulse rates, the enclosure maintains the IP20 protection class, so it must be mounted inside a panel. Internal conduction and forced-air cooling paths limit conversion losses to 310 W, and the climatic category 3K3 rating indicates suitability for typical control-cabinet dust levels and temperature variations.

Mechanical installation is simplified by a depth of 255 mm, a height of 330 mm, and a width of 170 mm, dimensions that fit common 300 mm deep enclosures. The inverter weighs 10 kg, which keeps handling straightforward during panel installation, and 7 mm mounting holes line up with standard M6 hardware. Motor leads can be routed up to 100 m when shielded, maintaining EMC compliance across extended cable runs. Continuous operation is permitted in atmospheres up to 95% relative humidity, provided condensation is prevented.
