UPSI-1208DPx
Revision 2-0
29
F12 Dynamic Powerboost
Valid from firmware version 2.2.1
With the dynamic power boost function, it is possible to temporarily draw a higher output power (overload)
from the UPS. As soon as an overload is detected when the threshold value is exceeded, this is possible in a
dynamic overload range of up to 58 seconds, before the output is disconnected.
During operation, the device constantly measures the output energy drawn over the last 58 seconds
(1 reading / second). This measured output energy is compared with the maximum possible output energy
(max. 5.57 kJ). If the value is smaller, the device continues to run and the output remains unlocked. If the value
is larger, the output is disconnected. The output energy will continue to be recorded and the output will not
be released again until the value falls below the maximum value.

Note:
The output power is determined by output current and output voltage. A current-dependent voltage drop can reduce the output voltage, which is why the output power varies
in some cases.

Example 1
E = 12 W · 2 sec + 48 W · 4 sec + 120 W · 8 sec + 84 W · 2 sec + 108 W · 13 sec + 60 W · 16 sec + 48 W · 4 sec + 120 W · 6 sec + 96 W · 2 sec + 72 W · 1 sec = 4884 Ws ≈ 4.88 kJ
UPS output keeps unlocked after second 58 because the output energy does not exceed 5.57 kJ.
