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 22.2.
