Output Current
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 23.1.
Peak current voltage dips typ. from 12V to 7V at 16A for 50ms, resistive load
typ. from 12V to 7V at 40A for 2ms, resistive load
typ. from 12V to 3.7V at 40A for 5ms, resistive load
