The
Power Consumption Factor (PCF) of contribution units connected
to a CCU has a bearing on the total number of such units that
can be connected. The maximum number of units quoted for a
CCU on this website and in the pdf downloads is based on all
units having a PCF of 1. This means that, for example, a stand-alone
DCN CCU LBB 3500/05, which can accommodate 90 units of power
of PCF can also accommodate 180 units of PCF 0.5.
