1.4 Power supply
The menu shows the voltages and the
temperature measured by the power
management board (PMB Voltages) and the
main CPU board in the Display unit(DU Voltages).
The measurement starts about 100 ms after a
start-up. The values in the column under
Mean
are the mean values of the last one second, the
Min
column shows the minimum mean value,
and the
Max
column the maximum mean value
of the voltages and temperature measured
during the current power ON.
The following voltages are measured by the
PMB in the Frame Unit:
Raw DC
+15V
14.65….15.35
–15V
-14.65...-15.35 V
+15VD
14.65...16.00 V
+5V
4.85...5.25 V
Temp (°C)
value corresponds with the Frame
Unit internal temperature measured by the PMB.
The numbers on this page are only directive and not absolute values.
The following voltages are measured by the Central Processing Board in the Display Unit:
+12V 11.50…12.50V
+3.3V 3.00…3.60V
VBUS 10.00…17.00V
Temp (°C)
value corresponds with the Display Unit internal temperature measured by the Central Processing
Board.
MPS input current
is the current fed to the Module Power Supply. The current should be <4A.
AC/DC capacity
in use is the capacity information achieved from the AC/DC unit by the PMB.
AC/DC voltage
is the AC/DC power unit output voltage measured by the PMB.
