Product Description:
KEB manufactures the 10.F4.S1D-4A11, a frequency inverter in the F4 Combivert Frequency Inverters series. Its role in industrial automation is to modulate the voltage and frequency delivered to an AC motor so machine speed can be matched to process demand while reducing electrical stress on the mechanical load. The inverter integrates drive logic, protective functions, and a braking stage in a compact enclosure. It is well suited for variable-speed machinery that benefits from controlled acceleration, stable running speed, and reduced mechanical shock during stopping.
The electronics comply with the electromagnetic compatibility limits of EN 61800-3, and operation is governed by a standard control platform that accepts typical analog or fieldbus commands. A built-in brake transistor diverts regenerated energy into a resistor to protect the DC link during rapid deceleration. For connected machines, the drive can deliver up to 4 kVA of apparent power and can operate motors rated as high as 2.2 kW. Thermal monitoring supervises heat-sink temperature during continuous operation. The enclosure carries an IP20 rating that helps prevent accidental contact with live parts when the unit is installed in a ventilated control panel.
The mechanical package measures 250 mm deep, 240 mm high, and 90 mm wide, so the unit fits shallow cabinets or densely packed machine frames. Its narrow width also leaves room for wiring ducts and adjacent components in compact panel layouts. Continuous service is supported as long as the heat sink remains at or below 85 °C, and installation is permitted at elevations up to 2000 m above sea level. A maximum relative humidity of 95% is tolerated without condensation, and the terminals accept 0.5 Nm of tightening torque to secure power and control conductors. With a unit weight of 3.5 kg, the inverter adds minimal mass to sliding or swing-out panel sections.
