Peak current capability (up to several ms)
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 25.1.
Peak current voltage dips typ. from 48V to 38 V at 10A for 50ms, resistive load
typ. from 48V to 35V at 25A for 2ms, resistive load
typ. from 48V to 28V at 25A for 5ms, resistive load
