Introduction
The 42X3* panel is LGE’s HD successor for the year 2007 of
the 42V7* panel.
9.2
Power Supply Unit (PSU)
9.2.1
Purpose
•
To convert an input voltage of 100
~
240 Volt AC to
voltages that the different boards and the panel need.
•
Output voltages: Vcc (5 V), Vs (180
~
200 V), and Va (60
~
65 V), all DC.
•
The PSU switches
“
OFF
”
automatically, when it detects
errors like short circuits.
Warning:
Voltages on the PSU reach 390 Volt maximum, so
be very careful when handling it!
