7.1 Introduction
FFE200 • Fundamental Front End Regenerative Power Supply Unit

FFE200 series is the Gefran solution for regenerative
power supply to be used as an alternative to traditional brak-
ADV200 - 4 • Basic
ing resistors.
Everytime there is no stringent harmonic distortion require-
ments, which by the way can be addressed by the AFE200
series, the Fundamental Front End technology allows to
supply the high power drive through the DC bus.

How the FFE200 application can provide benefits:
• Cabinet size Reduced
• No Complex filters required being the sole AC
• Choke enough to guarantee a sufficient level of har-
monic distortion.
• Efficiency enhancement of the internal power module
• Limited internal dissipative losses.
