Product Description:

The 10.F4.F3D-A015 frequency inverter is manufactured by KEB within the F4 Combivert Frequency Inverters series. Classified as a COMBIVERT F4 unit, it converts fixed-frequency mains power into a variable output that matches the torque and speed demands of asynchronous or synchronous AC motors used in conveyors, pump stations, and general machinery. By modulating voltage and frequency, the device enables precise closed-loop motion control, reduces mechanical stress, and supports energy-efficient operation across a broad range of industrial automation installations.

The inverter employs field-oriented control, so the drive processor calculates stator and rotor flux vectors in real time to maintain linear torque even at low speeds. Installation is simplified by the compact size D housing, which fits densely populated control panels. At the motor terminals, it can supply up to 2.2 kW of mechanical shaft power, while the converter section is rated for an apparent output of 4 kVA. An enclosure rating of IP20 allows installation in clean electrical cabinets where protection against accidental contact with internal components is required. The operating ambient temperature range of -10 to 45 °C supports continuous service on factory floors that are neither refrigerated nor exposed to elevated heat sources.

Built-in safeguards supplement the electrical capabilities of the inverter. An integrated filter and braking transistor attenuates conducted emissions and manages regenerative energy through the connected braking circuit during controlled deceleration. The pulse-width-modulated output operates at a carrier frequency near 2 kHz, balancing acoustic noise with switching losses for mid-power applications. The inverter can function at up to 95% relative humidity without condensation, permitting service in seasonally humid production areas when it is installed inside a suitable electrical cabinet.
