NOTE: DC-AC inverter is used to generate very high AC voltage, then support to LCD CCFT backlight user,
and is also responsible for the control of LCD brightness. Avoid touching the DC-AC inverter area while
the system unit is turned on.
NOTE: There is an EEPROM in the inverter, which stores its supported LCD type and ID code. If you replace
a new inverter or replace the LCD with a different brand, use Inverter ID utility to update the ID
information .

The maximum inrush current will be less than 50A and 100A when the adapter is
connected to 115Vac and 230Vac respectively.
It should provide an efficiency of 80% minimum, when measured at maximum
load under 115Vac.
