Peak current capability (up to several milliseconds)

The power supply can deliver a peak current which is higher than the specied 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 power supply. During this event, the capacitors will be

discharged and causes a voltage dip on the output. Detailed curves can be found in section 22.1.

Peak current voltage dips typ. from 12V to 7V at 9A for 50ms, resistive load
