Product Description:
The 15.F4.CEE-3420 is a frequency inverter manufactured by KEB for the F4 Combivert Frequency Inverters series. Classified as a COMBIVERT F4 unit, it is built in the E-size housing and operates in the 400 V voltage class. The product uses Compact control mode, and a Standard fieldbus option is present for basic networked drive functions. In automation cells, the inverter sits between the plant’s mains supply and an induction motor, modulating output frequency and voltage so that conveyor, fan, or pump speeds can be matched precisely to process demands.
The power section is designed for a three-phase supply and accepts line voltages from 305 to 500 V. Within this range, the drive can deliver a continuous output of 24 A, which corresponds to a nominal apparent power of 17 kVA at the motor terminals. When matched with correctly cooled machines, its output supports motors with up to 11 kW of rated shaft power. A fixed carrier frequency of 4 kHz controls the pulse-width-modulated signal that reconstructs the desired sine wave, balancing acoustic noise against switching losses. The accepted voltage range and continuous current must be considered when selecting cables, fuses, and upstream protection. The available motor output also helps determine whether the inverter is suitable for the connected load and its expected operating duty.
The enclosure carries an IP20 protection rating, so it must be mounted inside a cabinet to limit exposure to contaminants and prevent accidental contact. Continuous operation is permitted at ambient temperatures from -10 to 45 °C, and the design tolerates relative humidity up to 95% without condensation. These operating limits are suitable for typical control rooms and enclosed machinery installations where temperature and moisture remain controlled. The E-size frame uses the hole pattern found throughout the series, supporting orderly installation when multiple axes require units with identical mounting dimensions and performance. Adequate cabinet ventilation should be provided so heat from the inverter can escape while the unit operates continuously under load.
