Product Description:

The 13.F4.C1E-3220 is a frequency inverter manufactured by KEB as part of the F4 Combivert Frequency Inverters series. It serves as the power electronics stage between a three-phase AC supply and a motor, delivering regulated voltage and frequency so induction or synchronous motors can match changing load demands in automated equipment. By replacing mechanical speed control with electronic modulation, the device can improve energy use and support stable closed-loop motor performance in industrial cells. The regulated output also lets the connected motor accelerate, decelerate, and hold commanded speed without relying on fixed-speed operation.

The electrical interface accepts a mains supply of 180 to 260 V AC at the standard 50/60 Hz ±2 line frequency. Under nominal load, the inverter draws 26.5 A and delivers 24 A to the motor. Short-time current can rise to 36.5 A, and the overcurrent trip level is 43 A. Cable lugs up to 6 mm² can be connected to the terminals, and a 35 A upstream fuse can be used to coordinate protection with the converter. The power stage switches at 4 kHz, and transistor losses of 165 W are transferred to an aluminum heat sink that may operate at 73 °C. This switching behavior helps the inverter regulate motor current while the heat sink removes the thermal load created during operation.

For dynamic braking events, the unit uses an integrated transistor so returned energy can be dissipated without external braking hardware. It supports motor ratings up to 5.5 kW when ambient temperature remains within -10 to 45 °C. The enclosure is rated IP20, which provides protection against accidental contact with live parts but does not protect against liquid ingress. Because of that housing type, the inverter should be installed in a ventilated cabinet where dust, moisture, and other airborne contaminants are controlled.
