Product Description:

The 09.F4.C1D-1200 is a frequency inverter manufactured by KEB and supplied within the F4 Combivert Frequency Inverters series. Designed as a compact drive module, it converts constant mains power into a variable three-phase output that matches motor speed requirements. In automated conveyor lines, packaging machinery, and material-handling cells, the device provides torque control, soft starts, and energy savings by adjusting motor parameters without mechanical gear changes.

On the supply side, the inverter accepts a single-phase line in the 230 V class and draws a nominal input current of 14 A through terminals sized for 2.5 mm² conductors. Internally, the compact control platform drives the IGBT bridge and integrates a braking transistor so regenerated energy can be dissipated safely during rapid deceleration. At the motor terminals, the device supplies a nominal output current of 7 A, which corresponds to an apparent power of 2.8 kVA. Within this operating range, the unit can run motors up to 1.5 kW, while the D-style housing directs airflow across the heat sink and allows DIN-rail or panel mounting in small cabinets. Drive shutdown is initiated when phase current exceeds the 15 A overcurrent trip threshold, protecting semiconductors and connected machinery.

During intermittent overloads, the inverter can supply a short-time current of 12.6 A, supporting torque surges without violating thermal limits. Continuous dissipation is limited to a power loss of 70 W, and reliable operation is maintained while the heat sink temperature stays below 85 °C. Upstream protection is achieved with a maximum mains fuse rating of 20 A, matching the input current capability. The IP20 housing protects the electronics against solid objects larger than 12 mm, which is suitable for mounting inside enclosed control panels. Wiring uses the stated line cross section, and the single-phase architecture reduces the number of supply conductors needed.
