Product Description:

The 07.F4.S2C-M220 is a frequency inverter manufactured by KEB within the F4 Combivert Frequency Inverters series. It converts fixed-frequency AC supply power into a variable AC output so that small induction motors in conveyors, dosing pumps, and positioning stages can start, stop, and run at controlled speeds without mechanical gear changes. The compact housing fits small control cabinets, and the unit connects directly to simple speed-control circuits used in single-axis machinery. This type of drive is useful where basic motor speed adjustment is needed without a large panel footprint.

The drive is designed for single-phase input and operates in the 230 V class. Under rated conditions, it supplies 4 A of output current, which corresponds to 1.6 kVA of apparent power at the motor terminals. Its IGBT output stage can switch at up to 8 kHz, which helps produce smoother motor torque at low speed and can reduce audible motor noise compared with lower switching rates. Supply protection uses a 20 A fast-acting fuse, and the terminals accept 2.5 mm² conductors. The unit is compatible with standard 50 or 60 Hz utility power, which suits small machines connected to common single-phase branch circuits.

For short acceleration or braking intervals, the inverter can reach a peak current of 8.0 A. Its motor capacity is limited to 0.75 kW, making it appropriate for compact low-power installations where available panel space and thermal headroom are limited. The enclosure carries an IP20 rating for protected cabinet mounting, and the drive can operate at ambient humidity up to 95 % without condensation. It should be installed in a dry indoor enclosure rather than exposed directly on open machinery. Noncondensing operation is important in panels where temperature changes could otherwise lead to moisture on live components.
