4 System energy consumption
and dimmer setting
Because there is a largely linear relationship between the power
consumption of the DALI/DIM systems (lamp and ECG) and the dim-
mer setting, the power consumption PN(d) can be calculated for
each dimmer setting d (in percent) from the values PN100 % (100 %
nominal power, PN = Power Nominal) and PN1 % (nominal power of
1 %) (depending on ECG lamp combination, available on request):
