3.2.1 DC main power supply
The Power unit (figure 5) is energizing all internal components, the display and its backlight. Thereby
the power supply can vary in between 14 to 32 VDC. The emVIEW-12T/D has a power dissipation
with less than 9 W. Before connecting the DC main power supply the protective bonding conductor
(PE) must be connected. table 2 shows the measured power dissipation.
