7.1 Overcurrent protection
Each DC output connector can source up to a maximum rated current of 3.3 A.
If a short circuit occurs due to a damaged DIN plug DC cable or if a DC output connector is connected to a
device other than compatible products, 3.4 A or larger current may be output.
Once an overcurrent condition is detected, the PDU-1209 stops supplying power from the affected DC output
connecter temporarily. In order to notify you of the problem, the PDU-1209 outputs an alarm and it lights the
ALARM (DC12V) LED. When the overcurrent condition is corrected, the PDU-1209 re-establishes power to
the DC output connector automatically.
