1.1 Electrical
Power Requirements
Auto-ranging - 12V to 80V DC ± 25% (9V to 100V DC).
Operating Current
Total system current entering the V+ pin is a function of system volt-
age, LED alert/warning icons, backlight, LCD heater and sender loads.
The table below illustrates the typical and maximum operating current
for a panel with a V+ voltage of 12V with the sender inputs left as
open circuit. The LCD heater circuit typically consumes 310mA when
active. The backlight circuit typically consumes 30mA. For higher
V+ voltages the operating current is reduced accordingly.
