Product Description:

The 16.F4.C1G.M441 inverter is produced by KEB and belongs to the F4 Combivert Frequency Inverters series. It is an AC drive that modulates the voltage and frequency supplied to an induction motor so that speed and torque follow the command values set by a PLC or local keypad. In material-handling lines, pump systems, or fan applications, the unit serves as a compact controller that converts the factory’s three-phase mains into a regulated output waveform for dynamic process control.

Its control hardware uses a 10 bit analog input and a 15 bit digital encoder interface, giving fine resolution for speed references and feedback. The integrated braking transistor channels excess regenerative energy to an external resistor, avoiding DC-link overvoltage during rapid deceleration. The compact construction accepts motor leads up to 10 mm² and permits shielded cable runs as long as 100 m. With a rated output current of 33 A, the drive supplies up to 23 kVA of apparent power, while the input side draws 36.5 A at the plant bus bars. Frequency synthesis ranges from 0 Hz to 816 Hz, so high-speed spindles can be driven directly. The inverter aligns with 50/60 Hz utility grids and is protected by a maximum 50 A mains fuse specified for its input terminals.

For transient events, the inverter can deliver a peak phase current of 49.5 A for 30 seconds, enabling acceleration of machines that briefly need more torque than the continuous rating allows. When matched to a motor rated at 15 kW, the unit operates within its thermal range while still using the 400 V class DC link. The housing carries an IP20 protection class, so it must be installed inside a suitable cabinet with controlled airflow. Compliance with the 400 V voltage category allows connection to typical European and Asian power systems without a step-down transformer.
