Product Description:

The 13.F4.C3D-3410 is a frequency inverter produced by KEB for the F4 Combivert Frequency Inverters series. In an automation cell, it modulates the voltage and frequency supplied to an AC motor, allowing process-specific speed control while maintaining torque. Its compact design simplifies cabinet layout, and the unit serves as the active interface between a three-phase mains supply and asynchronous or synchronous motors used on conveyors, pumps, and positioning stages. By adjusting the output waveform to the motor, it supports controlled acceleration, steady running, and deceleration in variable-speed systems.

This inverter is wired to a three-phase grid in the 400 V voltage class and draws a nominal input current of 13.2 A. At the output terminals, it supplies 12 A of continuous current, which corresponds to 8.3 kVA of nominal apparent power for the connected motor. A factory-installed braking transistor handles regenerated energy during fast deceleration, and an integrated RFI filter reduces conducted emissions on the supply side. The control electronics use a compact topology that helps reduce panel depth, and the housing is the D type that matches F4 frame dimensions. Power conductors up to 4 mm² can be clamped directly, which keeps the power connection layout compact. The protective path includes a 25 A fuse for severe fault currents.

The power stage supports motors up to 5.5 kW. For intermittent overloads, it can operate at a carrier frequency of 2 kHz without derating and deliver up to 21.6 A during startup surges. This overload capacity supports short acceleration events and temporary load peaks. Hardware monitoring trips the inverter when phase current rises to 26.4 A, and a heat sink sensor supervises the temperature limit so switching losses stay within operating limits.
