POWER MEASUREMENT
The 3 factors to take a decision
Factor 1 :
Choice of Central Source Luminaires (CSL)
Ask your supplier abour their energy consumption.
Factor 2 :
Calculation of the power of a DC or AC energy sources
The power and voltage are defined by the specifications; then follow the methods below :
DC energy
Evacuation unit example consumption 3.6W = 25 Luminaires
Ambien unit = consuming 11W = 15
Evacuation : 25 x 3.6 W = 90 W + Ambient : 15 x 11 W = 165 W = Total power : 255 W
AC energy
Evacuation unit = 15 luminaires
Ambient = consuming 30 VA = 12 luminaires
Evacuation : 15 x 3 VA = 45 VA + Ambient : 12 x 30 VA = 360 VA = Total power : 405 VA
Factor 3 :
Definition of a Energy source. After calculating the power of the central source, APS France offers two ranges of products depending on the voltage of use
DC Energy
Recommended power :
Recommended margin 20% -> 255 + 20% = 306 W, SEC 48/360W
AC Energy
Recommended power :
Recommended margin 20 % -> 405 + 20 % = 486 VA, soit une SEA 600 VA
