1. When the AD board is in DPMS state:
1.1 The IP has been designed so that it operates with a power consumption of less than 0.6W of.
1.2 The Scaler consumes power up to 37mA
1.3 The power to the panel is switched off
2. When the AD board is operating normally:
2.1 The maximum power consumption of the panel lamps is described below (It may vary depending on
the panel manufacturer)
17" : 4*(7.0mA*650Vrms)=4* 4.55W=18.2W
2.2 The power consumption of the Panel Control board is as follows: 5V*645mA=3.23W
2.3 The power consumption of the Scaler is as follows: 3.3V*204mA + 1.8V*145mA = 0.93W
