Product Description:
The 15.F4.S1E-4A01 is a frequency inverter produced by KEB as part of the F4 Combivert Frequency Inverters series. This E-housing model is built for panel mounting and converts fixed three-phase mains power into a variable voltage and frequency supply so that induction or synchronous motors can be speed-controlled in conveyors, mixers, and other automated equipment. By regulating both parameters simultaneously, the drive supports smooth acceleration, efficient operation, and controlled deceleration that are important for repeatable machine cycles. Its panel-mounted format also helps keep wiring centralized inside the control cabinet, which supports orderly integration with other drive and control components.
An integrated brake transistor diverts regenerated energy into an external resistor with a typical value of 56 Ω, keeping the DC bus within safe limits during rapid stops. On the supply side, the unit draws a nominal current of 26.5 A, while its inverter section can deliver 24 A continuously to the motor windings. The apparent output capability reaches 17 kVA, matching motors rated up to 11 kW when operated on standard 400 V networks. Protective coordination is supported by a maximum permissible line fuse of 35 A. A standard control section provides start, stop, and speed reference functions, and the power electronics are housed in a format suited to compact cabinet layouts without adding unnecessary external components.
Total installation mass is 3.5 kg, and a front width of 130 mm helps conserve rail space in multi-axis panels. The enclosure carries an IP20 protection rating, meaning live parts are finger-safe but the drive should be installed in a clean, closed cabinet for protection from dust and moisture. Heat is removed through natural convection, so the unit can operate without a separate cooling fan when the cabinet layout provides appropriate airflow around the housing. The integrated braking function also supports applications with frequent stopping, where returned motor energy must be managed in a controlled way.
