DC POWER INPUT REQUIREMENTS
5.1 DC Power Input Lines
The DC Power Input Connector consists of two (2) positions wired numerically and supplied attached
to the Monitor as a chassis mounted connector per definitions listed in.

Figure 10. DC Power Input Connector- Pin Assignments
The DC Power Input Connector is a 2 pin MAT-N-LOK type with male pin contacts
AMP 1 480699
.
Pin number assignments are defined in Figure 11; shown below is the physical layout as seen by the
interface cable from the DC power source.

5.2 DC Input Voltage / Current
DC Input Voltage: 12 vdc nominal, + 0.4 vdc.
Over the specified input voltage range:
-
No loss of image synchronization occurs.
-
White display luminance level is within 10% of luminance at nominal input voltage.
-
DC Input Current: 4.3 amp maximum current draw (12.4-vdc applied) steady state
conditions.
Refer to Figure 12 for required current profile characteristics at “power–up” conditions.
The Monitor is not damaged by input voltages ranging from 0-vdc to 12.4-vdc".
