Keb F4 15kW F4 Series Inverter
KEB F4 15kW inverter overview: The KEB COMBIVERT a frequency inverter with DC-voltage link. It works according to the principle of the pulse-width modulation and serves exclusively for the stepless speed control of three-phase AC motors. The unit developed subject to the relevant safety standards and manufactured with the highest demands on quality. Condition for an unobjectionable operation the function-conform configuring of the drive and correct transport and storage as well as careful installation and connection.
The power circuit of a frequency inverter consists basically of a mains rectifier. The DC-link and an inverter at the output. The mains rectifier consists of an uncontrolled single or three-phase bridge connection, the single-phase design restricted to small powers. It converts the AC-voltage of the mains into a DC-voltage, which smoothed by the DC-link capacitor, thus in the ideal case.
The actual task of the frequency inverter, to produce an output voltage variable in frequency and amplitude for the control of the three-phase AC motor. Took over by the converter at the output. It makes available a 3-phase output voltage according to the principle of the pulse-width modulation. Which generates a sinusoidal current at the three-phase asynchronous motor.
