Product Description:

The 10.F4.C1D-6L10 frequency inverter is built by KEB and belongs to the F4 Combivert Frequency Inverters series. This unit sits between the plant’s three-phase mains and an AC motor, modulating voltage and frequency so that speed and torque can be matched to process demands in industrial automation. It replaces mechanical throttling with electronic regulation, improving energy use and extending motor life in conveyor lines, packaging equipment, and ventilation systems. The unit integrates control logic, power electronics, and braking circuitry in a compact chassis to simplify cabinet layouts.

Electrical ratings define how the inverter connects to the network and the driven machine. It is designed for a 400 V supply and accepts a 3-phase line, drawing a nominal input of 6.4 A. Internally, the converter delivers 4 kVA of apparent power, corresponding to an output current of 5.8 A under continuous duty. Compliance with the EMC standard EN 61800-3 limits conducted and radiated noise, while a shielded motor cable can extend up to 100 m without jeopardizing emissions or control accuracy. The inverter follows a voltage-source PWM topology, so line fusing and grounding must align with regional electrical codes.

The output stage can briefly energize loads up to 2.2 kW, supported by a short-time current of 10.4 A for acceleration peaks before the overcurrent trip activates at 12.7 A. A braking chopper routes excess energy to external resistors; the typical value is 270 Ω, with 82 Ω as the minimum allowed, and the circuit can sink 15 A to keep the DC bus within limits. Upstream protection calls for a 20 A mains fuse that matches the converter’s semiconductor rating. The housing carries an IP20 designation for cabinet mounting and weighs only 3.5 kg, easing installation on DIN rails or backplates.
