Peak current capability (up to several milliseconds)
The DC/DC converter can deliver a peak current, which is higher than the specified short term current. This helps to
start current demanding loads or to safely operate subsequent circuit breakers.
The extra current is supplied by the output capacitors inside the DC/DC converter. During this event, the capacitors will
be discharged and causes a voltage dip on the output. Detailed curves can be found in chapter 21.1.
