Product Description:
The 14.F4.C1E-4A02 is an AC frequency inverter built by KEB for the F4 Combivert Frequency Inverters series. The unit modulates the voltage-to-frequency ratio delivered to an induction motor, allowing closed-loop speed regulation and controlled acceleration in conveyors, pumps, and other automation axes. As part of an industrial drive chain, it converts fixed mains power into a variable output profile that the motor can follow, providing energy savings and smoother mechanical motion.
For electrical performance, the inverter delivers a continuous output apparent power of 11 kVA, matching motors whose rated mechanical demand reaches 7.5 kW. It accepts line supplies at 50/60 Hz, and KEB integrates a braking transistor so excess regenerative energy is diverted to an external resistor during rapid deceleration. The protective system is rated IP20, so the unit must be mounted inside a cabinet, but no extra sealing is required around the electronics. Electromagnetic compatibility follows EN 61800-3, and the compact control insert simplifies parameter entry without adding width to the E-class housing. The aluminum chassis marked Housing Design E attaches with 7 mm mounting holes that align with standard back-plate patterns.
Thermal and environmental limits align with automation cabinets in light industrial spaces. Continuous operation is permitted up to 45 °C, while storage is allowed up to 70 °C provided condensation is avoided. The inverter meets climatic category 3K3 and tolerates a relative humidity of 95 % without functional degradation when the air is non-condensing. Installation sites may be placed as high as 2000 m above sea level before derating becomes necessary. At 275 mm tall, the chassis fits vertically inside shallow enclosures, and its compact footprint leaves clearance for airflow around adjacent drives.
