DW2-UPS-250-DC
5 External power LED
The external power LED indicates that there is an external power supply connected and the batteries in the
DW2-UPS-250-DC are charging. The LED is only active when the Charger Power ON/OFF switch (7) is switched to
position "I".
6 Cutout for LCD battery status
To have a quick look at the battery status at any given time, the DW2-UPS-250-DC provides some cutouts for the 5
segment LCD charge level indicator of the installed battery packs. Further information regarding the 5 segment LCD
charge level indicator please refer to chapter " Smart battery packs ".
7 Charger ON/OFF switch for vehicle testing
To prevent the vehicle battery from draining, the DW2-UPS-250-DC charger can be switched off manually. During the
charger is deactivated, the measurement system does not draw any power from the vehicle battery. This prevents
from deep discharging the car battery e.g. when parked during weekend.
