Note: To calculate the total power consumption, add the power consumption of the
controller, output devices and readers connected. For example, if you connect 4 GV-EL202B
and 8 GV-DFR1352 to the GV-AS2120, the total power consumption will be 25.16 W.
z Each GV-EL202B uses 3.6 W * 4 = 14.4
W
z Each GV
-DFR1352 uses 0.72 W * 8 = 5.76 W
z GV-AS2120 uses 5 W
Total power consumption: 14.4 + 5.76 + 5 = 25.16 W
