Product Description:
The 15.F4.C1G-4A02 is a frequency inverter manufactured by KEB within the F4 Combivert Frequency Inverters series. It modulates the voltage and frequency supplied to an induction or synchronous motor so that speed, torque, and energy use match real-time process demands. Because the power stage is fully transistorized, the module replaces mechanical speed-control methods in conveyors, pumps, and general-purpose machinery. This arrangement allows the drive to respond quickly to changing load conditions while serving as a compact interface between the plant mains and the connected machine axis.
The inverter accepts a three-phase AC source in the 400 V class and draws a nominal input current of 26.5 A. Control flexibility is provided by 2 analog channels for continuous references and 4 digital lines for binary commands. An integrated braking transistor converts regenerated energy into heat so the DC link remains stable during rapid deceleration. This mix of interfaces supports simple start, stop, reference, and status functions in stand-alone equipment or larger control systems. Carrier switching occurs at a rated 8 kHz and can be increased to 16 kHz when lower acoustic noise is needed. These pulses are synchronized with the 50/60 Hz mains input to create a sinusoidal output waveform. Within these operating limits, the drive can deliver up to 11 kW of mechanical power to the motor while staying within the thermal capacity of its IGBT stack.
The output stage provides a nominal current of 24 A, which corresponds to an apparent power of 17 kVA at the motor terminals. Armored or shielded cable up to 100 m can be routed between the inverter and the motor, and a conductor cross-section of 6 mm² helps limit voltage drop. Shielding also helps reduce electrical interference between the inverter cable and nearby control wiring. Internal heat loss is limited to 290 W, which helps keep enclosure temperatures manageable when the unit is mounted in a ventilated cabinet. An IP20 housing protects the internal circuitry against accidental finger contact and settled dust, but it should be installed away from moisture or direct spray. The unit is intended for protected indoor mounting rather than exposed field installation.
