QC-CM-75
The QC-CM-75 commercial model is used to store energy that is returned
during the electric motor braking processes.
The are also appropriate for systems that sporadically demand high
current peaks from the power DC BUS, which in turn increases the
capacity of the DC BUS.
From the energy point of view, installing a capacitor module is more
efficient than installing external braking resistors.
