Discharge current of output capacitors is not included.

**) The extra current to charge network capacitors is available as soon as power comes on and immediately after the end of an output short

circuit or output overload.

Peak current capability (up to several milliseconds)

The power supply 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 power supply. 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.
