Product Description:
KEB manufactures the 09.F4.C3D-3420 as part of the F4 Combivert Frequency Inverters series. The unit is a cabinet-mounted AC drive intended to regulate induction or synchronous motors in small process machines and material-handling stations. By controlling voltage and frequency simultaneously, it matches motor torque to load and improves efficiency in compatible motor applications. Its design suits industrial automation systems that need compact drives with field-adjustable parameters and integrated analog or digital command inputs. This arrangement supports flexible speed control without requiring a large standalone drive package.
The inverter is fed by a three-phase mains connection and draws 4.5 A of input current under rated conditions. Internally, it can deliver a continuous motor current of 4.1 A and an apparent power throughput of 2.8 kVA. A carrier signal at 4 kHz governs the IGBT output, producing a synthesized sine wave whose frequency can be swept up to 816 Hz. This range supports high-speed operation in suitable spindle or blower applications. The control section samples references with 10-bit analog and 15-bit digital resolution, helping the drive follow process commands with adequate granularity. These electrical limits set the available range for speed regulation and torque boost without exceeding thermal ratings.
During short overloads, the current may rise to 7.4 A for 30 seconds, allowing the drive to start high-inertia loads or ride through brief transients. The connected motor may be rated up to 1.5 kW, and steady operation is supported at ambient temperatures up to 45 °C. Storage is permissible to 70 °C when the cabinet is de-energized. The enclosure is rated IP20, which provides basic finger protection once installed. The housing measures 90 mm wide, 210 mm deep, and 264 mm high, allowing dense panel layouts while preserving the airflow space the drive needs.
