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 24.1.
Peak current voltage dips typ. from 24V to 18V at 10A for 50ms, resistive load
typ. from 24V to 15V at 20A for 2ms, resistive load
typ. from 24V to 11.5V at 20A for 5ms, resistive load
