Product Description:
The 05.F4.S0C-M220 is a compact frequency inverter manufactured by KEB and supplied within the F4 Combivert Frequency Inverters series. Designed for a single-phase power connection, it delivers three-phase motor power at its output. It modulates voltage and frequency to regulate induction motor speed in automated conveyors, pumps, and small machine axes. This approach lets the motor follow changing process demands without relying on mechanical speed-changing devices. It is intended for compact automation equipment where adjustable motor speed improves process control and reduces unnecessary motor stress. Because the inverter creates a controlled output waveform, it can support smoother starts than a direct line connection.
This inverter accepts an input frequency of 50/60 Hz, and the line side uses one input phase protected by a 10 A fuse. Internally, the pulse-width-modulated stage can switch up to 8 kHz, allowing fine torque control while limiting audible noise during normal operation. At the output, it delivers a nominal apparent power of 0.9 kVA and supplies up to 2.3 A across three phases, matching fractional-kilowatt motors without oversizing the power stage. Short-term load demands are supported by an overload reserve of 200%, which helps the drive tolerate brief acceleration peaks and temporary load changes. The electronic assembly remains finger-safe with an enclosure rating of IP20, and continuous operation produces about 35 W of heat loss, so the cabinet must provide enough airflow to remove that heat. Using a single input phase also helps where a full three-phase supply is not available at the installation point.
During startup or sudden load surges, the drive can produce a peak output of 4.6 A for up to 30 seconds, providing additional torque without exceeding semiconductor limits. It has a rated motor match of 0.37 kW, which suits many light industrial actuators and small conveyor drives. The housing measures 90 × 230 × 115 mm and weighs 1.5 kg, so it can be mounted on a DIN rail or plate in tight control cabinets where available panel space is limited. Reliable operation is specified up to an installation altitude of 2000 m, because thinner air at higher elevations reduces cooling effectiveness. The compact enclosure also helps the unit fit beside contactors, filters, and terminal blocks in shallow cabinets.
