Attribute Description
Input voltage Nom 24V DC
Input voltage ranges Nom 22.5…30V DC Continuous operation, see Figure 3
.
30…35V DC Temporarily allowed, no damage to the DC-UPS.
(2)
35V DC Absolute maximum input voltage with no damage to the DC-UPS.
0…22.5V DC The DC-UPS changes to Buffer mode and delivers output voltage
from the battery if the input is above the turn-on level before and
all other buffer conditions are fulfilled.
Allowed input voltage ripple Max 1.5V pp
1V pp
Bandwidth < 400 Hz
Bandwidth 400 Hz to 1 kHz
Allowed voltage between input and
earth (ground)
Max 60V DC or 42.4V AC
Turn-on voltage Typ 22.8V DC The output does not switch On if the input voltage does not
exceed this level.
Max 23V DC

Internal current consumption
Current consumption for battery charging in constant current
mode at 24V input. See Figure 13.

External capacitors on the input No limitation
(1) The unit shows ‘Check Wiring’ with the red LED and buffering is not possible.
(2) The total input current is the sum of the output current, the current that is required to charge the battery during the charging process and the current that is needed to supply the
DC-UPS itself. See Figure 4
. This calculation does not apply in overload situations where the DC-UPS limits the output current. See Figure 5.
(3) This is the input current and not the current that flows into the battery during charging. See for the battery current.
