Product Description:
The 12.F4.C1D-4001 is a frequency inverter manufactured by KEB within the F4 Combivert Frequency Inverters series. It serves as the interface between the plant supply and three-phase motors, converting fixed mains frequency into a regulated output that supports variable-speed control. By regulating motor voltage, current, and flux, the device supports accurate positioning, soft acceleration, and efficient operation in assembly lines, material-handling frames, and process equipment. The inverter is supplied in a compact drive package intended for cabinet mounting where space is limited.
At full load, the inverter supports a maximum rated motor power of 4 kW, making it suitable for induction machines used on conveyors and small process tools. Its continuous output current is 9.5 A, and this value sets the thermal sizing for busbars and motor leads during steady operation. The apparent power transferable to the motor terminals reaches 6.6 kVA. For transient starts or shock loads, the drive permits a short-time current of 17.1 A, delivering brief torque peaks without tripping. Deceleration energy is routed through an integrated braking transistor that can divert up to 10 A into an external resistor to help prevent DC-link overvoltage.
In addition to performance values, the drive’s mechanical and operating limits support reliable installation. Its open-frame housing carries a protection rating of IP20, so it must be installed inside a switchgear enclosure. Conducted and radiated emissions comply with EN 61800-3, which helps support system-level compliance. The D-size frame accepts a minimum braking resistor of 82 Ω, while KEB recommends 150 Ω for general duty cycles. Overcurrent trips occur at 20.9 A, and all power terminals are secured with a tightening torque of 0.5 Nm. The electronics remain fully supported at site altitudes up to 2000 m, and the compact control variant helps reduce required panel depth.
