Product Description:

The 13.F6.K1D-39MA is an AC inverter drive produced by KEB for the F6 Combivert Inverter Drives series. As a mains-fed power stage, it converts three-phase supply energy into a variable-frequency, variable-voltage output so motion controllers can regulate induction or synchronous motors in automated machinery. The unit operates between the facility power bus and the connected motor, where it adjusts torque and speed to match process demands while providing electronic protection and monitoring.

The input section is rated at 400 V and remains functional within a ±10% line tolerance, allowing stable operation on typical European or international utility grids. At the motor terminals, it delivers a continuous phase current of 12 A, which corresponds to a usable apparent power of 8.3 kVA and supports a mechanical output of 5.5 kW under nominal conditions. The drive’s switching devices operate at a base frequency of 4 kHz. This carrier rate can be used when calculating harmonic content and cable shielding requirements. Short-term overloads are handled by a peak phase current of 21.6 A, providing headroom for acceleration cycles without causing a trip. The standby state draws only 20 W, conserving energy during plant downtime, while the control logic continuously supervises thermal and electrical limits.

When tighter dynamic performance is needed, the switching frequency can be raised to 16 kHz. This higher carrier frequency lowers motor acoustic noise but produces additional switching losses. The housing has an IP20 protection rating, so it must be installed inside a clean control cabinet but does not require special gasketing. Its dimensions of 250 mm in height, 90 mm in width, and 181 mm in depth support high-density installation, while the compact footprint leaves room for external EMC filters and braking resistors without requiring a larger enclosure.
