So that the Industrial PC still has a monitor output in case of a power failure, a Control Panel can be
connected to the UPS output of the power supply unit. Even after a power failure there is a voltage of 24 V
DC
between the UPS output and the negative pole of the battery pack. The maximum load is 1.4 A (max. 2.5 A
from year of manufacture 2016).
Once the PC has been de-energized via the UPS software, the UPS output is switched to 0 V. A connected
panel is switched off.
