15.F4.C0G-3420 by KEB

The KEB 15.F4.C0G-3420 is a robust member of the F4 Combivert Frequency Inverters series, designed for precise speed and torque control in three-phase motor applications. This inverter delivers an Output Nominal Power of 17 KVA and supports a Max. Rated motor power of 11 kW, making it ideal for medium-duty industrial drives. Housed in a compact, IP20-rated enclosure, the device integrates an air blower to maintain optimal thermal conditions. Its primary function is to convert DC link voltage into a high-frequency AC output, providing pulsating current intervals to drive three-phase motors with accuracy and reliability.

In terms of technical specifications, the 15.F4.C0G-3420 operates over a Mains Voltage range of 305–500 V and a Mains Frequency of 50–60 Hz, accommodating global power standards. It features a nominal input current of 26.5 A and supports an output frequency range of 0–100 Hz for versatile speed variation. The inverter’s internal inductance of 0.50 mH mitigates current ripple, while the shielded motor line accommodates runs up to 100 m without performance degradation. Environmental resilience is ensured by its Climatic Category 3K3 in accordance with EN 50179, allowing operation in moderate industrial atmospheres.

Additional features include a maximum relative humidity tolerance of 95% and a protective system rated IP20, safeguarding internal electronics from accidental contact. A standard 12-month warranty underscores the manufacturer’s confidence in product durability. The integrated DC-link capacitor and inrush-current-limiting resistor ensure smooth start-up and reliable operation under varying load conditions. Compatible exclusively with three-phase AC motors, this frequency inverter adheres strictly to industrial safety norms. In industrial automation contexts, the 15.F4.C0G-3420 delivers enhanced efficiency, reduced maintenance, and consistent performance, offering end users significant productivity gains and operational reliability.
