Product Description:

The 10.F4.C1D-4L20 frequency inverter is produced by KEB and belongs to the F4 Combivert Frequency Inverters series. As an AC drive, it converts fixed mains voltage into a variable three-phase output so that induction motors can be started smoothly and run at the required speed in automated conveyors, pumps, and positioners. This model is intended for cabinet-mounted machinery that needs a space-saving drive solution for motors in the low-kilowatt class, allowing energy savings and process consistency across diverse industrial tasks.

The drive is supplied in housing size D, a footprint that aligns with KEB rails inside 250 mm deep panels. Its electronics follow the Compact control architecture, which integrates braking and interface functions without add-on modules. Electrically, the inverter supports up to 2.2 kW of rated motor power, while its output stage is dimensioned for 4 kVA apparent power. Thermal management is critical because the heat sink may reach 85 °C before derating occurs, so adequate airflow must be provided. An IP20 protection rating allows finger-safe access yet requires installation in a clean, dry enclosure.

For ambient endurance the unit is assigned climatic category 3K3, suitable for workshops with moderate dust and temperature variations. Field terminals use screw clamps that should be fastened to 0.5 Nm to maintain reliable contact. The control board offers extensive user-configurable I/O: 2 analog inputs accommodate speed references, one analog output transmits diagnostic values, 4 digital inputs accept run and preset commands, one digital output provides status signaling, and two programmable relay contacts can indicate run or fault states. These resources minimize the need for external interface modules and allow direct connection to simple sensors, switches, and control relays.
