2.3 ABOUT THE CFW-11M G2 RB AND CFW-11W G2 RB

The CFW-11M G2 RB and CFW-11W G2 RB regenerative frequency converters are the second generation of the
CFW-11M RB and CFW-11W RB regenerative frequency converter line respectively. The main differences in relation
to the previous generation are the following:
Smaller. The CFW-11M G2 RB is shorter and slimmer than the CFW-11M RB, allowing the installation of three
„
UP11 G2 RB in a panel with columns 800 mm wide and 2000 mm high. The CFW-11W G2 RB is shorter, slimmer
and less deep than the CFW-11W RB, allowing the installation of three UP11W G2 in a panel with columns 800
mm wide, 2000 mm high and 600 mm deep.
More modern. State-of-the-art components have increased the power of the converters.
„
The CFW-11M G2 RB and CFW-11W G2 RB regenerative frequency converters are high-performance products
that enable the rectification of three-phase lines with the following advantages:
Low harmonic distortion in the input current.
„
Capacity to return energy to the line (regeneration), enabling high braking torques.
„
The CFW-11M G2 RB and CFW-11W G2 RB regenerative frequency converters have a modular design, with
configurations containing one to five power units (UP11 G2 or UP11W G2), one control unit (UC11RB G2) and
wiring cables. The modular assembly increases the converter reliability and simplifies its maintenance. There is a
single control unit (UC11RB G2) which can control up to five UP11s G2 or five UP11Ws G2.
