Peak current capability (up to several ms)
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 cause a voltage dip on the output. Detailed curves can be found in chapter 27.1.
